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=...)

Change span to div due to div being in the whitelisted tags per @waylan's comment under @chris's answer.
It appears that Firefox and Chrome don't render any style attributes any more at all.
