If your blog template is rendered entirely in CSS, and you have a float inside a float, please apply a line-height to the container to solve IE’s Peekaboo Bug. People have known about this bug since 2003, and I guess Microsoft isn’t going to fix it anytime soon. I personally discovered the solution via Google, as I was trying to make an all-CSS design and running into the same problem.
Yes, yes, IE blows. But a lot of people still use it (including me), so suck it up!
