A week or so back I saw the upgraded New York Times home page and especially impressive to me was the top section where the rest of the page scrolled underneath it. It stuck in position where it was. Great idea, and I haven’t seen it on many other sites.
So I designed a WordPress theme that was similar (not in design, but with the static header). The result is the Digitalis WordPress Theme. It is a dark-/light-blue theme with a static header. The rest of the blog theme scrolls underneath it. It works well in FireFox, IE7, Opera, and presumably Safari but I can’t test that. It breaks in IE6/5 but then again, if you’re still using that you’re still probably using typewriters too (c’mon, upgrade people!)
It has the usual bells and whistles on it, widgets, gravatars, all the SEO upgrades built in, and the standard array of sidebar sections. It is built and tested on WP-2.6.2 and should withstand upgrades in the future.
