Possible values are `True` for yes, `False` for no and + `None` for auto.

Defaults to `True`. - >>> html = markdown.markdown(text, - ... extensions=['codehilite(guess_lang=False)'] - ... ) + Using `False` will prevent Pygments from guessing the language, and thus + highlighting blocks only when you explicitly set the language. -To assign a CSS class differant than the default ('codehilite') on the -code's wrapping div, define a custom class with the `css_class` setting. +* **css_class**: + Set CSS class name for the wrapper `<div>` tag. Defaults to + `codehilite`. - >>> html = markdown.markdown(text, - ... extensions=['codehilite(css_class=myclass)'] - ... ) +* **pygments_style**: + Pygments HTML Formatter Style (ColorScheme). Defaults to `default`. + + !!! Note + This is useful only when `noclasses` is set to `True`, otherwise the + CSS style shall be provided by the end user. +* **noclasses**: + Use inline styles instead of CSS classes.
