title: Legacy Attributes Extension # Legacy Attributes ## Summary The Legacy Attributes extension restores Python-Markdown's original attribute setting syntax. Older versions of Python Markdown (prior to 3.0) included built-in and undocumented support for defining attributes on elements. Most users have never made use of the syntax and it has been deprecated in favor of [Attribute Lists](attr_list.md). This extension restores the legacy behavior for users who have existing documents which use the syntax. ## Syntax Attributes are defined by including the following within the element you wish to assign the attributes to: ```md {@key=value} ``` For example, to define a class to a paragraph: ```md A paragraph with the attribute defined {@class=foo}anywhere within. ``` Which results in the following output: ```html
A paragraph with the attribute defined anywhere within.
``` The same applies for inline elements: ```md Some *emphasized{@id=bar}* text. ``` ```htmlSome emphasized text.
You can also define attributes in images: ```md ![Alt text{@id=baz}](path/to/image.jpg) ``` ```html
