问题
This gives a pretty thorough description of how HTML elements are interpreted by markdown. But it does not discuss styles.
So far, the only thing I can get to work is image width.
- I can't find a list anywhere of what is accepted/rendered
- It appears that the
style="....."attribute is completely ignored. - I can't even find a list of the old-fashioned style attributes (as opposed to the style attribute
style=...)

EDIT
Change span to div due to div being in the whitelisted tags per @waylan's comment under @chris's answer.
EDIT 2
It appears that firefox and chrome don't render any style attributes any more at all.
回答1:
After GitHub converts Markdown to HTML,
The HTML is sanitized, aggressively removing things that could harm you and your kin—such as
scripttags, inline-styles, andclassoridattributes. See the sanitization filter for the full whitelist.
You're right: style tags are not included in the whitelist. They are ignored.
The permitted attributes differ by tag. I recommend referring to the sanitization filter link above. It leads to a fairly readable Ruby source file.
