Is it worth writing CSS that plays nice with IE versions prior to 6? I took a look at my site stats and I do get a few visits from IE5 and IE5.5.

I was checking out the new blog's design in IE5 and the 2 column layout just wasn't working. I backed up my old CSS file, dug up a few tutorials, and started playing around with a clean slate. There are hacks to get IE5 playing nicely with a 2-column layout, but then I realised that something as simple as an overflowing PRE tag causes the whole thing to fall apart. Setting an overflow:hidden property for the wrapping DIV takes care of that but it's still something I'd rather not do, since I've already got the usual PRE word wrap cross-browser sludge in place. I feel like I'm slapping mud patties on top of mud patties just to keep some crufty old browser happy.

Is it worth it? I feel guilty/sloppy about not doing it, but it is a major PITA.
