Markdown: Syntax

+ + + +

Note: This document is itself written using Markdown; you +can see the source for it by adding '.text' to the URL.

+
+

Overview

+ +

Philosophy

+ +

Markdown is intended to be as easy-to-read and easy-to-write as is feasible.

+

Readability, however, is emphasized above all else. A Markdown-formatted +document should be publishable as-is, as plain text, without looking +like it's been marked up with tags or formatting instructions. While +Markdown's syntax has been influenced by several existing text-to-HTML +filters -- including Setext, atx, Textile, reStructuredText, +Grutatext, and EtText -- the single biggest source of +inspiration for Markdown's syntax is the format of plain text email.

+

To this end, Markdown's syntax is comprised entirely of punctuation +characters, which punctuation characters have been carefully chosen so +as to look like what they mean. E.g., asterisks around a word actually +look like *emphasis*. Markdown lists look like, well, lists. Even +blockquotes look like quoted passages of text, assuming you've ever +used email.

+

Inline HTML

+ +

Markdown's syntax is intended for one purpose: to be used as a +format for writing for the web.

+

Markdown is not a replacement for HTML, or even close to it. Its +syntax is very small, corresponding only to a very small subset of +HTML tags. The idea is not to create a syntax that makes it easier +to insert HTML tags. In my opinion, HTML tags are already easy to +insert. The idea for Markdown is to make it easy to read, write, and +edit prose. HTML is a publishing format; Markdown is a writing +format. Thus, Markdown's formatting syntax only addresses issues that +can be conveyed in plain text.

+

For any markup that is not covered by Markdown's syntax, you simply +use HTML itself. There's no need to preface it or delimit it to +indicate that you're switching from Markdown to HTML; you just use +the tags.

+

The only restrictions are that block-level HTML elements -- e.g. <div>, +<table>, <pre>, <p>, etc. -- must be separated from surrounding +content by blank lines, and the start and end tags of the block should +not be indented with tabs or spaces. Markdown is smart enough not +to add extra (unwanted) <p> tags around HTML block-level tags.

+

For example, to add an HTML table to a Markdown article:

+
This is a regular paragraph.
+
+<table>
+    <tr>
+        <td>Foo</td>
+    </tr>
+</table>
+
+This is another regular paragraph.
+
+

Note that Markdown formatting syntax is not processed within block-level +HTML tags. E.g., you can't use Markdown-style *emphasis* inside an +HTML block.

+

Span-level HTML tags -- e.g. <span>, <cite>, or <del> -- can be +used anywhere in a Markdown paragraph, list item, or header. If you +want, you can even use HTML tags instead of Markdown formatting; e.g. if +you'd prefer to use HTML <a> or <img> tags instead of Markdown's +link or image syntax, go right ahead.

+

Unlike block-level HTML tags, Markdown syntax is processed within +span-level tags.

+

Automatic Escaping for Special Characters

+ +

In HTML, there are two characters that demand special treatment: < +and &. Left angle brackets are used to start tags; ampersands are +used to denote HTML entities. If you want to use them as literal +characters, you must escape them as entities, e.g. &lt;, and +&amp;.

+

Ampersands in particular are bedeviling for web writers. If you want to +write about 'AT&T', you need to write 'AT&amp;T'. You even need to +escape ampersands within URLs. Thus, if you want to link to:

+
http://images.google.com/images?num=30&q=larry+bird
+
+

you need to encode the URL as:

+
http://images.google.com/images?num=30&amp;q=larry+bird
+
+

in your anchor tag href attribute. Needless to say, this is easy to +forget, and is probably the single most common source of HTML validation +errors in otherwise well-marked-up web sites.

+

Markdown allows you to use these characters naturally, taking care of +all the necessary escaping for you. If you use an ampersand as part of +an HTML entity, it remains unchanged; otherwise it will be translated +into &amp;.

+

So, if you want to include a copyright symbol in your article, you can write:

+
&copy;
+
+

and Markdown will leave it alone. But if you write:

+
AT&T
+
+

Markdown will translate it to:

+
AT&amp;T
+
+

Similarly, because Markdown supports inline HTML, if you use +angle brackets as delimiters for HTML tags, Markdown will treat them as +such. But if you write:

+
4 < 5
+
+

Markdown will translate it to:

+
4 &lt; 5
+
+

However, inside Markdown code spans and blocks, angle brackets and +ampersands are always encoded automatically. This makes it easy to use +Markdown to write about HTML code. (As opposed to raw HTML, which is a +terrible format for writing about HTML syntax, because every single < +and & in your example code needs to be escaped.)

+
+

Block Elements

+ +

Paragraphs and Line Breaks

+ +

A paragraph is simply one or more consecutive lines of text, separated +by one or more blank lines. (A blank line is any line that looks like a +blank line -- a line containing nothing but spaces or tabs is considered +blank.) Normal paragraphs should not be intended with spaces or tabs.

+

The implication of the "one or more consecutive lines of text" rule is +that Markdown supports "hard-wrapped" text paragraphs. This differs +significantly from most other text-to-HTML formatters (including Movable +Type's "Convert Line Breaks" option) which translate every line break +character in a paragraph into a <br /> tag.

+

When you do want to insert a <br /> break tag using Markdown, you +end a line with two or more spaces, then type return.

+

Yes, this takes a tad more effort to create a <br />, but a simplistic +"every line break is a <br />" rule wouldn't work for Markdown. +Markdown's email-style blockquoting and multi-paragraph list items +work best -- and look better -- when you format them with hard breaks.

+ + +

Markdown supports two styles of headers, Setext and atx.

+

Setext-style headers are "underlined" using equal signs (for first-level +headers) and dashes (for second-level headers). For example:

+
This is an H1
+=============
+
+This is an H2
+-------------
+
+

Any number of underlining ='s or -'s will work.

+

Atx-style headers use 1-6 hash characters at the start of the line, +corresponding to header levels 1-6. For example:

+
# This is an H1
+
+## This is an H2
+
+###### This is an H6
+
+

Optionally, you may "close" atx-style headers. This is purely +cosmetic -- you can use this if you think it looks better. The +closing hashes don't even need to match the number of hashes +used to open the header. (The number of opening hashes +determines the header level.) :

+
# This is an H1 #
+
+## This is an H2 ##
+
+### This is an H3 ######
+
+

Blockquotes

+ +

Markdown uses email-style > characters for blockquoting. If you're +familiar with quoting passages of text in an email message, then you +know how to create a blockquote in Markdown. It looks best if you hard +wrap the text and put a > before every line:

+
> This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+> consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+> Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+> 
+> Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+> id sem consectetuer libero luctus adipiscing.
+
+

Markdown allows you to be lazy and only put the > before the first +line of a hard-wrapped paragraph:

+
> This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+> Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+id sem consectetuer libero luctus adipiscing.
+
+

Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by +adding additional levels of >:

+
> This is the first level of quoting.
+>
+> > This is nested blockquote.
+>
+> Back to the first level.
+
+

Blockquotes can contain other Markdown elements, including headers, lists, +and code blocks:

+
> ## This is a header.
+> 
+> 1.   This is the first list item.
+> 2.   This is the second list item.
+> 
+> Here's some example code:
+> 
+>     return shell_exec("echo $input | $markdown_script");
+
+

Any decent text editor should make email-style quoting easy. For +example, with BBEdit, you can make a selection and choose Increase +Quote Level from the Text menu.

+

Lists

+ +

Markdown supports ordered (numbered) and unordered (bulleted) lists.

+

Unordered lists use asterisks, pluses, and hyphens -- interchangably +-- as list markers:

+
*   Red
+*   Green
+*   Blue
+
+

is equivalent to:

+
+   Red
++   Green
++   Blue
+
+

and:

+
-   Red
+-   Green
+-   Blue
+
+

Ordered lists use numbers followed by periods:

+
1.  Bird
+2.  McHale
+3.  Parish
+
+

It's important to note that the actual numbers you use to mark the +list have no effect on the HTML output Markdown produces. The HTML +Markdown produces from the above list is:

+
<ol>
+<li>Bird</li>
+<li>McHale</li>
+<li>Parish</li>
+</ol>
+
+

If you instead wrote the list in Markdown like this:

+
1.  Bird
+1.  McHale
+1.  Parish
+
+

or even:

+
3. Bird
+1. McHale
+8. Parish
+
+

you'd get the exact same HTML output. The point is, if you want to, +you can use ordinal numbers in your ordered Markdown lists, so that +the numbers in your source match the numbers in your published HTML. +But if you want to be lazy, you don't have to.

+

If you do use lazy list numbering, however, you should still start the +list with the number 1. At some point in the future, Markdown may support +starting ordered lists at an arbitrary number.

+

List markers typically start at the left margin, but may be indented by +up to three spaces. List markers must be followed by one or more spaces +or a tab.

+

To make lists look nice, you can wrap items with hanging indents:

+
*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+
+

But if you want to be lazy, you don't have to:

+
*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+viverra nec, fringilla in, laoreet vitae, risus.
+*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+Suspendisse id sem consectetuer libero luctus adipiscing.
+
+

If list items are separated by blank lines, Markdown will wrap the +items in <p> tags in the HTML output. For example, this input:

+
*   Bird
+*   Magic
+
+

will turn into:

+
<ul>
+<li>Bird</li>
+<li>Magic</li>
+</ul>
+
+

But this:

+
*   Bird
+
+*   Magic
+
+

will turn into:

+
<ul>
+<li><p>Bird</p></li>
+<li><p>Magic</p></li>
+</ul>
+
+

List items may consist of multiple paragraphs. Each subsequent +paragraph in a list item must be intended by either 4 spaces +or one tab:

+
1.  This is a list item with two paragraphs. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+    mi posuere lectus.
+
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+    vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+    sit amet velit.
+
+2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+
+

It looks nice if you indent every line of the subsequent +paragraphs, but here again, Markdown will allow you to be +lazy:

+
*   This is a list item with two paragraphs.
+
+    This is the second paragraph in the list item. You're
+only required to indent the first line. Lorem ipsum dolor
+sit amet, consectetuer adipiscing elit.
+
+*   Another item in the same list.
+
+

To put a blockquote within a list item, the blockquote's > +delimiters need to be indented:

+
*   A list item with a blockquote:
+
+    > This is a blockquote
+    > inside a list item.
+
+

To put a code block within a list item, the code block needs +to be indented twice -- 8 spaces or two tabs:

+
*   A list item with a code block:
+
+        <code goes here>
+
+

It's worth noting that it's possible to trigger an ordered list by +accident, by writing something like this:

+
1986. What a great season.
+
+

In other words, a number-period-space sequence at the beginning of a +line. To avoid this, you can backslash-escape the period:

+
1986\. What a great season.
+
+

Code Blocks

+ +

Pre-formatted code blocks are used for writing about programming or +markup source code. Rather than forming normal paragraphs, the lines +of a code block are interpreted literally. Markdown wraps a code block +in both <pre> and <code> tags.

+

To produce a code block in Markdown, simply indent every line of the +block by at least 4 spaces or 1 tab. For example, given this input:

+
This is a normal paragraph:
+
+    This is a code block.
+
+

Markdown will generate:

+
<p>This is a normal paragraph:</p>
+
+<pre><code>This is a code block.
+</code></pre>
+
+

One level of indentation -- 4 spaces or 1 tab -- is removed from each +line of the code block. For example, this:

+
Here is an example of AppleScript:
+
+    tell application "Foo"
+        beep
+    end tell
+
+

will turn into:

+
<p>Here is an example of AppleScript:</p>
+
+<pre><code>tell application "Foo"
+    beep
+end tell
+</code></pre>
+
+

A code block continues until it reaches a line that is not indented +(or the end of the article).

+

Within a code block, ampersands (&) and angle brackets (< and >) +are automatically converted into HTML entities. This makes it very +easy to include example HTML source code using Markdown -- just paste +it and indent it, and Markdown will handle the hassle of encoding the +ampersands and angle brackets. For example, this:

+
    <div class="footer">
+        &copy; 2004 Foo Corporation
+    </div>
+
+

will turn into:

+
<pre><code>&lt;div class="footer"&gt;
+    &amp;copy; 2004 Foo Corporation
+&lt;/div&gt;
+</code></pre>
+
+

Regular Markdown syntax is not processed within code blocks. E.g., +asterisks are just literal asterisks within a code block. This means +it's also easy to use Markdown to write about Markdown's own syntax.

+

Horizontal Rules

+ +

You can produce a horizontal rule tag (<hr />) by placing three or +more hyphens, asterisks, or underscores on a line by themselves. If you +wish, you may use spaces between the hyphens or asterisks. Each of the +following lines will produce a horizontal rule:

+
* * *
+
+***
+
+*****
+
+- - -
+
+---------------------------------------
+
+_ _ _
+
+
+

Span Elements

+ + + +

Markdown supports two style of links: inline and reference.

+

In both styles, the link text is delimited by [square brackets].

+

To create an inline link, use a set of regular parentheses immediately +after the link text's closing square bracket. Inside the parentheses, +put the URL where you want the link to point, along with an optional +title for the link, surrounded in quotes. For example:

+
This is [an example](http://example.com/ "Title") inline link.
+
+[This link](http://example.net/) has no title attribute.
+
+

Will produce:

+
<p>This is <a href="http://example.com/" title="Title">
+an example</a> inline link.</p>
+
+<p><a href="http://example.net/">This link</a> has no
+title attribute.</p>
+
+

If you're referring to a local resource on the same server, you can +use relative paths:

+
See my [About](/about/) page for details.
+
+

Reference-style links use a second set of square brackets, inside +which you place a label of your choosing to identify the link:

+
This is [an example][id] reference-style link.
+
+

You can optionally use a space to separate the sets of brackets:

+
This is [an example] [id] reference-style link.
+
+

Then, anywhere in the document, you define your link label like this, +on a line by itself:

+
[id]: http://example.com/  "Optional Title Here"
+
+

That is:

+ +

The link URL may, optionally, be surrounded by angle brackets:

+
[id]: <http://example.com/>  "Optional Title Here"
+
+

You can put the title attribute on the next line and use extra spaces +or tabs for padding, which tends to look better with longer URLs:

+
[id]: http://example.com/longish/path/to/resource/here
+    "Optional Title Here"
+
+

Link definitions are only used for creating links during Markdown +processing, and are stripped from your document in the HTML output.

+

Link definition names may constist of letters, numbers, spaces, and punctuation -- but they are not case sensitive. E.g. these two links:

+
[link text][a]
+[link text][A]
+
+

are equivalent.

+

The implicit link name shortcut allows you to omit the name of the +link, in which case the link text itself is used as the name. +Just use an empty set of square brackets -- e.g., to link the word +"Google" to the google.com web site, you could simply write:

+
[Google][]
+
+

And then define the link:

+
[Google]: http://google.com/
+
+

Because link names may contain spaces, this shortcut even works for +multiple words in the link text:

+
Visit [Daring Fireball][] for more information.
+
+

And then define the link:

+
[Daring Fireball]: http://daringfireball.net/
+
+

Link definitions can be placed anywhere in your Markdown document. I +tend to put them immediately after each paragraph in which they're +used, but if you want, you can put them all at the end of your +document, sort of like footnotes.

+

Here's an example of reference links in action:

+
I get 10 times more traffic from [Google] [1] than from
+[Yahoo] [2] or [MSN] [3].
+
+  [1]: http://google.com/        "Google"
+  [2]: http://search.yahoo.com/  "Yahoo Search"
+  [3]: http://search.msn.com/    "MSN Search"
+
+

Using the implicit link name shortcut, you could instead write:

+
I get 10 times more traffic from [Google][] than from
+[Yahoo][] or [MSN][].
+
+  [google]: http://google.com/        "Google"
+  [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+  [msn]:    http://search.msn.com/    "MSN Search"
+
+

Both of the above examples will produce the following HTML output:

+
<p>I get 10 times more traffic from <a href="http://google.com/"
+title="Google">Google</a> than from
+<a href="http://search.yahoo.com/" title="Yahoo Search">Yahoo</a>
+or <a href="http://search.msn.com/" title="MSN Search">MSN</a>.</p>
+
+

For comparison, here is the same paragraph written using +Markdown's inline link style:

+
I get 10 times more traffic from [Google](http://google.com/ "Google")
+than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+[MSN](http://search.msn.com/ "MSN Search").
+
+

The point of reference-style links is not that they're easier to +write. The point is that with reference-style links, your document +source is vastly more readable. Compare the above examples: using +reference-style links, the paragraph itself is only 81 characters +long; with inline-style links, it's 176 characters; and as raw HTML, +it's 234 characters. In the raw HTML, there's more markup than there +is text.

+

With Markdown's reference-style links, a source document much more +closely resembles the final output, as rendered in a browser. By +allowing you to move the markup-related metadata out of the paragraph, +you can add links without interrupting the narrative flow of your +prose.

+

Emphasis

+ +

Markdown treats asterisks (*) and underscores (_) as indicators of +emphasis. Text wrapped with one * or _ will be wrapped with an +HTML <em> tag; double *'s or _'s will be wrapped with an HTML +<strong> tag. E.g., this input:

+
*single asterisks*
+
+_single underscores_
+
+**double asterisks**
+
+__double underscores__
+
+

will produce:

+
<em>single asterisks</em>
+
+<em>single underscores</em>
+
+<strong>double asterisks</strong>
+
+<strong>double underscores</strong>
+
+

You can use whichever style you prefer; the lone restriction is that +the same character must be used to open and close an emphasis span.

+

Emphasis can be used in the middle of a word:

+
un*fucking*believable
+
+

But if you surround an * or _ with spaces, it'll be treated as a +literal asterisk or underscore.

+

To produce a literal asterisk or underscore at a position where it +would otherwise be used as an emphasis delimiter, you can backslash +escape it:

+
\*this text is surrounded by literal asterisks\*
+
+

Code

+ +

To indicate a span of code, wrap it with backtick quotes (`). +Unlike a pre-formatted code block, a code span indicates code within a +normal paragraph. For example:

+
Use the `printf()` function.
+
+

will produce:

+
<p>Use the <code>printf()</code> function.</p>
+
+

To include a literal backtick character within a code span, you can use +multiple backticks as the opening and closing delimiters:

+
``There is a literal backtick (`) here.``
+
+

which will produce this:

+
<p><code>There is a literal backtick (`) here.</code></p>
+
+

The backtick delimiters surrounding a code span may include spaces -- +one after the opening, one before the closing. This allows you to place +literal backtick characters at the beginning or end of a code span:

+
A single backtick in a code span: `` ` ``
+
+A backtick-delimited string in a code span: `` `foo` ``
+
+

will produce:

+
<p>A single backtick in a code span: <code>`</code></p>
+
+<p>A backtick-delimited string in a code span: <code>`foo`</code></p>
+
+

With a code span, ampersands and angle brackets are encoded as HTML +entities automatically, which makes it easy to include example HTML +tags. Markdown will turn this:

+
Please don't use any `<blink>` tags.
+
+

into:

+
<p>Please don't use any <code>&lt;blink&gt;</code> tags.</p>
+
+

You can write this:

+
`&#8212;` is the decimal-encoded equivalent of `&mdash;`.
+
+

to produce:

+
<p><code>&amp;#8212;</code> is the decimal-encoded
+equivalent of <code>&amp;mdash;</code>.</p>
+
+

Images

+ +

Admittedly, it's fairly difficult to devise a "natural" syntax for +placing images into a plain text document format.

+

Markdown uses an image syntax that is intended to resemble the syntax +for links, allowing for two styles: inline and reference.

+

Inline image syntax looks like this:

+
![Alt text](/path/to/img.jpg)
+
+![Alt text](/path/to/img.jpg "Optional title")
+
+

That is:

+ +

Reference-style image syntax looks like this:

+
![Alt text][id]
+
+

Where "id" is the name of a defined image reference. Image references +are defined using syntax identical to link references:

+
[id]: url/to/image  "Optional title attribute"
+
+

As of this writing, Markdown has no syntax for specifying the +dimensions of an image; if this is important to you, you can simply +use regular HTML <img> tags.

+
+

Miscellaneous

+ + + +

Markdown supports a shortcut style for creating "automatic" links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:

+
<http://example.com/>
+
+

Markdown will turn this into:

+
<a href="http://example.com/">http://example.com/</a>
+
+

Automatic links for email addresses work similarly, except that +Markdown will also perform a bit of randomized decimal and hex +entity-encoding to help obscure your address from address-harvesting +spambots. For example, Markdown will turn this:

+
<address@example.com>
+
+

into something like this:

+
<a href="&#x6D;&#x61;i&#x6C;&#x74;&#x6F;:&#x61;&#x64;&#x64;&#x72;&#x65;
+&#115;&#115;&#64;&#101;&#120;&#x61;&#109;&#x70;&#x6C;e&#x2E;&#99;&#111;
+&#109;">&#x61;&#x64;&#x64;&#x72;&#x65;&#115;&#115;&#64;&#101;&#120;&#x61;
+&#109;&#x70;&#x6C;e&#x2E;&#99;&#111;&#109;</a>
+
+

which will render in a browser as a clickable link to "address@example.com".

+

(This sort of entity-encoding trick will indeed fool many, if not +most, address-harvesting bots, but it definitely won't fool all of +them. It's better than nothing, but an address published in this way +will probably eventually start receiving spam.)

+

Backslash Escapes

+ +

Markdown allows you to use backslash escapes to generate literal +characters which would otherwise have special meaning in Markdown's +formatting syntax. For example, if you wanted to surround a word with +literal asterisks (instead of an HTML <em> tag), you can backslashes +before the asterisks, like this:

+
\*literal asterisks\*
+
+

Markdown provides backslash escapes for the following characters:

+
\   backslash
+`   backtick
+*   asterisk
+_   underscore
+{}  curly braces
+[]  square brackets
+()  parentheses
+#   hash mark
++   plus sign
+-   minus sign (hyphen)
+.   dot
+!   exclamation mark

Overview

+ +

Philosophy

+ +Markdown is intended to be as easy-to-read and easy-to-write as is feasible. + +Readability, however, is emphasized above all else. A Markdown-formatted +document should be publishable as-is, as plain text, without looking +like it's been marked up with tags or formatting instructions. While +Markdown's syntax has been influenced by several existing text-to-HTML +filters -- including [Setext] [1], [atx] [2], [Textile] [3], [reStructuredText] [4], +[Grutatext] [5], and [EtText] [6] -- the single biggest source of +inspiration for Markdown's syntax is the format of plain text email. + + [1]: http://docutils.sourceforge.net/mirror/setext.html + [2]: http://www.aaronsw.com/2002/atx/ + [3]: http://textism.com/tools/textile/ + [4]: http://docutils.sourceforge.net/rst.html + [5]: http://www.triptico.com/software/grutatxt.html + [6]: http://ettext.taint.org/doc/ + +To this end, Markdown's syntax is comprised entirely of punctuation +characters, which punctuation characters have been carefully chosen so +as to look like what they mean. E.g., asterisks around a word actually +look like \*emphasis\*. Markdown lists look like, well, lists. Even +blockquotes look like quoted passages of text, assuming you've ever +used email. + + + +

Inline HTML

+ +Markdown's syntax is intended for one purpose: to be used as a +format for *writing* for the web. + +Markdown is not a replacement for HTML, or even close to it. Its +syntax is very small, corresponding only to a very small subset of +HTML tags. The idea is *not* to create a syntax that makes it easier +to insert HTML tags. In my opinion, HTML tags are already easy to +insert. The idea for Markdown is to make it easy to read, write, and +edit prose. HTML is a *publishing* format; Markdown is a *writing* +format. Thus, Markdown's formatting syntax only addresses issues that +can be conveyed in plain text. + +For any markup that is not covered by Markdown's syntax, you simply +use HTML itself. There's no need to preface it or delimit it to +indicate that you're switching from Markdown to HTML; you just use +the tags. + +The only restrictions are that block-level HTML elements -- e.g. `
`, +``, `
`, `
`, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) `
` tags around HTML block-level tags.
+
+For example, to add an HTML table to a Markdown article:
+
+    This is a regular paragraph.
+
+
+ + + +
Foo
+ + This is another regular paragraph. + +Note that Markdown formatting syntax is not processed within block-level +HTML tags. E.g., you can't use Markdown-style `*emphasis*` inside an +HTML block. + +Span-level HTML tags -- e.g. ``, ``, or `` -- can be +used anywhere in a Markdown paragraph, list item, or header. If you +want, you can even use HTML tags instead of Markdown formatting; e.g. if +you'd prefer to use HTML `` or `` tags instead of Markdown's +link or image syntax, go right ahead. + +Unlike block-level HTML tags, Markdown syntax *is* processed within +span-level tags. + + +

Automatic Escaping for Special Characters

+ +In HTML, there are two characters that demand special treatment: `<` +and `&`. Left angle brackets are used to start tags; ampersands are +used to denote HTML entities. If you want to use them as literal +characters, you must escape them as entities, e.g. `<`, and +`&`. + +Ampersands in particular are bedeviling for web writers. If you want to +write about 'AT&T', you need to write '`AT&T`'. You even need to +escape ampersands within URLs. Thus, if you want to link to: + + http://images.google.com/images?num=30&q=larry+bird + +you need to encode the URL as: + + http://images.google.com/images?num=30&q=larry+bird + +in your anchor tag `href` attribute. Needless to say, this is easy to +forget, and is probably the single most common source of HTML validation +errors in otherwise well-marked-up web sites. + +Markdown allows you to use these characters naturally, taking care of +all the necessary escaping for you. If you use an ampersand as part of +an HTML entity, it remains unchanged; otherwise it will be translated +into `&`. + +So, if you want to include a copyright symbol in your article, you can write: + + © + +and Markdown will leave it alone. But if you write: + + AT&T + +Markdown will translate it to: + + AT&T + +Similarly, because Markdown supports [inline HTML](#html), if you use +angle brackets as delimiters for HTML tags, Markdown will treat them as +such. But if you write: + + 4 < 5 + +Markdown will translate it to: + + 4 < 5 + +However, inside Markdown code spans and blocks, angle brackets and +ampersands are *always* encoded automatically. This makes it easy to use +Markdown to write about HTML code. (As opposed to raw HTML, which is a +terrible format for writing about HTML syntax, because every single `<` +and `&` in your example code needs to be escaped.) + + +* * * + + +

Block Elements

+ + +

Paragraphs and Line Breaks

+ +A paragraph is simply one or more consecutive lines of text, separated +by one or more blank lines. (A blank line is any line that looks like a +blank line -- a line containing nothing but spaces or tabs is considered +blank.) Normal paragraphs should not be intended with spaces or tabs. + +The implication of the "one or more consecutive lines of text" rule is +that Markdown supports "hard-wrapped" text paragraphs. This differs +significantly from most other text-to-HTML formatters (including Movable +Type's "Convert Line Breaks" option) which translate every line break +character in a paragraph into a `
` tag. + +When you *do* want to insert a `
` break tag using Markdown, you +end a line with two or more spaces, then type return. + +Yes, this takes a tad more effort to create a `
`, but a simplistic +"every line break is a `
`" rule wouldn't work for Markdown. +Markdown's email-style [blockquoting][bq] and multi-paragraph [list items][l] +work best -- and look better -- when you format them with hard breaks. + + [bq]: #blockquote + [l]: #list + + + + + +Markdown supports two styles of headers, [Setext] [1] and [atx] [2]. + +Setext-style headers are "underlined" using equal signs (for first-level +headers) and dashes (for second-level headers). For example: + + This is an H1 + ============= + + This is an H2 + ------------- + +Any number of underlining `=`'s or `-`'s will work. + +Atx-style headers use 1-6 hash characters at the start of the line, +corresponding to header levels 1-6. For example: + + # This is an H1 + + ## This is an H2 + + ###### This is an H6 + +Optionally, you may "close" atx-style headers. This is purely +cosmetic -- you can use this if you think it looks better. The +closing hashes don't even need to match the number of hashes +used to open the header. (The number of opening hashes +determines the header level.) : + + # This is an H1 # + + ## This is an H2 ## + + ### This is an H3 ###### + + +

Blockquotes

+ +Markdown uses email-style `>` characters for blockquoting. If you're +familiar with quoting passages of text in an email message, then you +know how to create a blockquote in Markdown. It looks best if you hard +wrap the text and put a `>` before every line: + + > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet, + > consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. + > Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. + > + > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse + > id sem consectetuer libero luctus adipiscing. + +Markdown allows you to be lazy and only put the `>` before the first +line of a hard-wrapped paragraph: + + > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet, + consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus. + Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus. + + > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse + id sem consectetuer libero luctus adipiscing. + +Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by +adding additional levels of `>`: + + > This is the first level of quoting. + > + > > This is nested blockquote. + > + > Back to the first level. + +Blockquotes can contain other Markdown elements, including headers, lists, +and code blocks: + + > ## This is a header. + > + > 1. This is the first list item. + > 2. This is the second list item. + > + > Here's some example code: + > + > return shell_exec("echo $input | $markdown_script"); + +Any decent text editor should make email-style quoting easy. For +example, with BBEdit, you can make a selection and choose Increase +Quote Level from the Text menu. + + +

Lists

+ +Markdown supports ordered (numbered) and unordered (bulleted) lists. + +Unordered lists use asterisks, pluses, and hyphens -- interchangably +-- as list markers: + + * Red + * Green + * Blue + +is equivalent to: + + + Red + + Green + + Blue + +and: + + - Red + - Green + - Blue + +Ordered lists use numbers followed by periods: + + 1. Bird + 2. McHale + 3. Parish + +It's important to note that the actual numbers you use to mark the +list have no effect on the HTML output Markdown produces. The HTML +Markdown produces from the above list is: + +
    +
  1. Bird
    2. +
  2. McHale
    3. +
  3. Parish
    4. +
+ +If you instead wrote the list in Markdown like this: + + 1. Bird + 1. McHale + 1. Parish + +or even: + + 3. Bird + 1. McHale + 8. Parish + +you'd get the exact same HTML output. The point is, if you want to, +you can use ordinal numbers in your ordered Markdown lists, so that +the numbers in your source match the numbers in your published HTML. +But if you want to be lazy, you don't have to. + +If you do use lazy list numbering, however, you should still start the +list with the number 1. At some point in the future, Markdown may support +starting ordered lists at an arbitrary number. + +List markers typically start at the left margin, but may be indented by +up to three spaces. List markers must be followed by one or more spaces +or a tab. + +To make lists look nice, you can wrap items with hanging indents: + + * Lorem ipsum dolor sit amet, consectetuer adipiscing elit. + Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, + viverra nec, fringilla in, laoreet vitae, risus. + * Donec sit amet nisl. Aliquam semper ipsum sit amet velit. + Suspendisse id sem consectetuer libero luctus adipiscing. + +But if you want to be lazy, you don't have to: + + * Lorem ipsum dolor sit amet, consectetuer adipiscing elit. + Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi, + viverra nec, fringilla in, laoreet vitae, risus. + * Donec sit amet nisl. Aliquam semper ipsum sit amet velit. + Suspendisse id sem consectetuer libero luctus adipiscing. + +If list items are separated by blank lines, Markdown will wrap the +items in `

` tags in the HTML output. For example, this input: + + * Bird + * Magic + +will turn into: + +

    +
  • Bird
    • +
  • Magic
    • +
+ +But this: + + * Bird + + * Magic + +will turn into: + +
    +

  • Bird

    • +

  • Magic

    • +
+ +List items may consist of multiple paragraphs. Each subsequent +paragraph in a list item must be intended by either 4 spaces +or one tab: + + 1. This is a list item with two paragraphs. Lorem ipsum dolor + sit amet, consectetuer adipiscing elit. Aliquam hendrerit + mi posuere lectus. + + Vestibulum enim wisi, viverra nec, fringilla in, laoreet + vitae, risus. Donec sit amet nisl. Aliquam semper ipsum + sit amet velit. + + 2. Suspendisse id sem consectetuer libero luctus adipiscing. + +It looks nice if you indent every line of the subsequent +paragraphs, but here again, Markdown will allow you to be +lazy: + + * This is a list item with two paragraphs. + + This is the second paragraph in the list item. You're + only required to indent the first line. Lorem ipsum dolor + sit amet, consectetuer adipiscing elit. + + * Another item in the same list. + +To put a blockquote within a list item, the blockquote's `>` +delimiters need to be indented: + + * A list item with a blockquote: + + > This is a blockquote + > inside a list item. + +To put a code block within a list item, the code block needs +to be indented *twice* -- 8 spaces or two tabs: + + * A list item with a code block: + + + + +It's worth noting that it's possible to trigger an ordered list by +accident, by writing something like this: + + 1986. What a great season. + +In other words, a *number-period-space* sequence at the beginning of a +line. To avoid this, you can backslash-escape the period: + + 1986\. What a great season. + + + +

Code Blocks

+ +Pre-formatted code blocks are used for writing about programming or +markup source code. Rather than forming normal paragraphs, the lines +of a code block are interpreted literally. Markdown wraps a code block +in both `
` and `` tags.
+
+To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:
+
+    This is a normal paragraph:
+
+        This is a code block.
+
+Markdown will generate:
+
+    
This is a normal paragraph:

+
+    
This is a code block.
+    

+
+One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:
+
+    Here is an example of AppleScript:
+
+        tell application "Foo"
+            beep
+        end tell
+
+will turn into:
+
+    
Here is an example of AppleScript:

+
+    
tell application "Foo"
+        beep
+    end tell
+    

+
+A code block continues until it reaches a line that is not indented
+(or the end of the article).
+
+Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:
+
+        

+            © 2004 Foo Corporation
+        

+
+will turn into:
+
+    
<div class="footer">
+        &copy; 2004 Foo Corporation
+    </div>
+    

+
+Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.
+
+
+
+
Horizontal Rules

+
+You can produce a horizontal rule tag (`
`) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:
+
+    * * *
+
+    ***
+
+    *****
+	
+    - - -
+
+    ---------------------------------------
+
+	_ _ _
+
+
+* * *
+
+
Span Elements

+
+
+
+Markdown supports two style of links: *inline* and *reference*.
+
+In both styles, the link text is delimited by [square brackets].
+
+To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an *optional*
+title for the link, surrounded in quotes. For example:
+
+    This is [an example](http://example.com/ "Title") inline link.
+
+    [This link](http://example.net/) has no title attribute.
+
+Will produce:
+
+    
This is 
+    an example inline link.

+
+    
This link has no
+    title attribute.

+
+If you're referring to a local resource on the same server, you can
+use relative paths:
+
+    See my [About](/about/) page for details.   
+
+Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:
+
+    This is [an example][id] reference-style link.
+
+You can optionally use a space to separate the sets of brackets:
+
+    This is [an example] [id] reference-style link.
+
+Then, anywhere in the document, you define your link label like this,
+on a line by itself:
+
+    [id]: http://example.com/  "Optional Title Here"
+
+That is:
+
+*   Square brackets containing the link identifier (optionally
+    indented from the left margin using up to three spaces);
+*   followed by a colon;
+*   followed by one or more spaces (or tabs);
+*   followed by the URL for the link;
+*   optionally followed by a title attribute for the link, enclosed
+    in double or single quotes.
+
+The link URL may, optionally, be surrounded by angle brackets:
+
+    [id]:   "Optional Title Here"
+
+You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:
+
+    [id]: http://example.com/longish/path/to/resource/here
+        "Optional Title Here"
+
+Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.
+
+Link definition names may constist of letters, numbers, spaces, and punctuation -- but they are *not* case sensitive. E.g. these two links:
+
+	[link text][a]
+	[link text][A]
+
+are equivalent.
+
+The *implicit link name* shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+"Google" to the google.com web site, you could simply write:
+
+	[Google][]
+
+And then define the link:
+
+	[Google]: http://google.com/
+
+Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:
+
+	Visit [Daring Fireball][] for more information.
+
+And then define the link:
+	
+	[Daring Fireball]: http://daringfireball.net/
+
+Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.
+
+Here's an example of reference links in action:
+
+    I get 10 times more traffic from [Google] [1] than from
+    [Yahoo] [2] or [MSN] [3].
+
+      [1]: http://google.com/        "Google"
+      [2]: http://search.yahoo.com/  "Yahoo Search"
+      [3]: http://search.msn.com/    "MSN Search"
+
+Using the implicit link name shortcut, you could instead write:
+
+    I get 10 times more traffic from [Google][] than from
+    [Yahoo][] or [MSN][].
+
+      [google]: http://google.com/        "Google"
+      [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+      [msn]:    http://search.msn.com/    "MSN Search"
+
+Both of the above examples will produce the following HTML output:
+
+    
I get 10 times more traffic from Google than from
+    Yahoo
+    or MSN.

+
+For comparison, here is the same paragraph written using
+Markdown's inline link style:
+
+    I get 10 times more traffic from [Google](http://google.com/ "Google")
+    than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+    [MSN](http://search.msn.com/ "MSN Search").
+
+The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.
+
+With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.
+
+
+
Emphasis

+
+Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
+emphasis. Text wrapped with one `*` or `_` will be wrapped with an
+HTML `` tag; double `*`'s or `_`'s will be wrapped with an HTML
+`` tag. E.g., this input:
+
+    *single asterisks*
+
+    _single underscores_
+
+    **double asterisks**
+
+    __double underscores__
+
+will produce:
+
+    single asterisks
+
+    single underscores
+
+    double asterisks
+
+    double underscores
+
+You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.
+
+Emphasis can be used in the middle of a word:
+
+    un*fucking*believable
+
+But if you surround an `*` or `_` with spaces, it'll be treated as a
+literal asterisk or underscore.
+
+To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:
+
+    \*this text is surrounded by literal asterisks\*
+
+
+
+
Code

+
+To indicate a span of code, wrap it with backtick quotes (`` ` ``).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:
+
+    Use the `printf()` function.
+
+will produce:
+
+    
Use the printf() function.

+
+To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:
+
+    ``There is a literal backtick (`) here.``
+
+which will produce this:
+
+    
There is a literal backtick (`) here.

+
+The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:
+
+	A single backtick in a code span: `` ` ``
+	
+	A backtick-delimited string in a code span: `` `foo` ``
+
+will produce:
+
+	
A single backtick in a code span: `

+	
+	
A backtick-delimited string in a code span: `foo`

+
+With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:
+
+    Please don't use any `` tags.
+
+into:
+
+    
Please don't use any <blink> tags.

+
+You can write this:
+
+    `—` is the decimal-encoded equivalent of `—`.
+
+to produce:
+
+    
&#8212; is the decimal-encoded
+    equivalent of &mdash;.

+
+
+
+
Images

+
+Admittedly, it's fairly difficult to devise a "natural" syntax for
+placing images into a plain text document format.
+
+Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: *inline* and *reference*.
+
+Inline image syntax looks like this:
+
+    ![Alt text](/path/to/img.jpg)
+
+    ![Alt text](/path/to/img.jpg "Optional title")
+
+That is:
+
+*   An exclamation mark: `!`;
+*   followed by a set of square brackets, containing the `alt`
+    attribute text for the image;
+*   followed by a set of parentheses, containing the URL or path to
+    the image, and an optional `title` attribute enclosed in double
+    or single quotes.
+
+Reference-style image syntax looks like this:
+
+    ![Alt text][id]
+
+Where "id" is the name of a defined image reference. Image references
+are defined using syntax identical to link references:
+
+    [id]: url/to/image  "Optional title attribute"
+
+As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML `` tags.
+
+
+* * *
+
+
+
Miscellaneous

+
+
+
+Markdown supports a shortcut style for creating "automatic" links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:
+
+    
+    
+Markdown will turn this into:
+
+    http://example.com/
+
+Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:
+
+    
+
+into something like this:
+
+    address@exa
+    mple.com
+
+which will render in a browser as a clickable link to "address@example.com".
+
+(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)
+
+
+
+
Backslash Escapes

+
+Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML `` tag), you can backslashes
+before the asterisks, like this:
+
+    \*literal asterisks\*
+
+Markdown provides backslash escapes for the following characters:
+
+    \   backslash
+    `   backtick
+    *   asterisk
+    _   underscore
+    {}  curly braces
+    []  square brackets
+    ()  parentheses
+    #   hash mark
+	+	plus sign
+	-	minus sign (hyphen)
+    .   dot
+    !   exclamation mark
+
