So, for the past hour I’ve been trying to figure out why a website I’m working simply fails to render on IE 6. I finally traced it down to a rogue button element, which appeared to be well-constructed but was still making IE 6 barf spectacularly. In the off-chance this ever happens to anyone else, here’s a tip: ensure that your button elements are constructed with a real closing tag as opposed to the short form (or whatever the real name for it is).
i.e.: <button> </button> instead of <button />
