Conditional CSS files for IE6 are hacks, so are the png fixes and the suckerfish js. They're all things we use to make the layout display in a way that isn't native to the browser. It's things we use to fix up IE6's problems, hence, they are hacks. I code... like 20 to 30 sites a month, and you just need the hacks. Not on everything, but the strict minimum.

It's everywhere, from display:inline to fix double margin, to adding a height:1% on elements.

So, I agree with rochow, unless your page is composed of 'hello world", you're gonna need hacks.
