Common CSS Instructions - Which Is Faster?

[Chris77]

Sitepoint Members,

Which would be faster for loading a webpage:


CSS: div.firstimg{..presentation instruction here won't be used anywhere else on the page ....}

HTML: <div class="someimg" title=".." >....</a>

or

CSS: .firstimg{...presentation instruction here won't be used anywhere else on the page...}

HTML: <div class="someimg" title="..." >....</a>

Thanks,

Chris
