How to Build a Website That Looks Good in All Browsers

We're pretty much stopping an IE 8 now unless someone specifically requests it. We know that I'm leaving gaps for no JavaScript, so all content is always available. There's on the freshtiltsoil.com, we just redid our homepage on the process section. And there's some panels that slide over and around one of those little moving cube games. But without the way I'm doing that, just adding and removing a class and then using a transition or an animation to move the block over. If you don't have that capability, the block just kind of snaps over and I'm fine with that.
