IE7.css is at 146 lines and counting…

How good is IE7? I was wondering about that today as I reloaded it to do another batch of bug fixing. The proof may be in your CSS pudding.

We are using conditional comments to import either ie6.css or ie7.css to control our hacks.



So far, the ie6 style sheet is 342 lines long, including lots of whitespace and comments. A good portion of that is for re-assigning gif background images instead of png. The rest is an assortment of invoking hasLayout, box model changes, and the ever-popular z-index bugs.

I copied this style sheet, commented everything out and began re-introducing the rules to build the IE7 style sheet. I ditched the gif and z-index hacks. The most common hacks are for hasLayout and double-margin float. I’m still using a set of hacks to re-configure my background images that are being measured from the bottom up.

So, how big is the IE7 style sheet? Right now, we are looking at 146 lines of code, including white space and comments. That’s still a hefty amount and I’m not done fixing bugs. Yes, IE7 is much better than IE6, but still a far cry from the others.
