It doesn't say "M C squared", but "M C and then a 2 that lives a little higher up than the rest of the text". HTML was never meant to mark up mathematical expressions...that's what MathML is for. I've seen <sup> used for referencing footnotes as well... so you see it's not that <sup> has semantic value, but it's purely describing the visual appearance. > W3C uses a hidden <hr> tag on > the home page to separate page content from the copyright info. The W3C site is not always the best example for the purest, most semantic use of markup, css, accessibility or anything else, so - regardless of this actual discussion on <hr> - I wouldn't use something found in their markup as an absolute proof.
