S2, here I come

I managed to get S2 to give me a back to top link on each entry. Yay, customization!

S2's rigidly-defined layers are a little annoying, but I'm glad it's reasonably hackable. I'm a little disappointed CSS2 has a content element on :before and :after that can't represent a link (text, image, bullet, counter, but not a link!), but it got me poking around S2, so something good came of the W3C's omission.
