please do away with presentation junk in the html!!

IMHO styling html elements using the style="" property is never a good idea not even if something is only used once.
Inline styles cannot be overridden by stylesheets, unless you use the !important 'hack'.
(I say hack, because it's a way to compensate for bad styling practices or browser failures)

Javascript animations use the style property a lot. Hopefully in the future when css animations are supported in more browser that will be a thing of the past too.
