It doesn't matter if you do all the error checking in the world, or if you have the most beautiful graphics, if your site or application design isn't usable, it's not going to do well. Get input and advice on usability and user interface issues here.
The grey box on the left with the rounded corners should look like it does in FF. But in IE 6 and 7 the bottom of it has a flat edge as if the background is overflowing. Any clues?
Ah yeah, that's how I did that last one (which worked) but I was trying to be smart and make one that will stretch in all directions. Mine works when you put that code by itself, it's just breaking in its surroundings although the page validates.
I'll give it another look after I've eaten and if I can't solve it I'll just go back to the fixed-width version
shongaks, the code I showed is flexible and does work very good. And in all browsers. Only if you need a completely fluid box (expanding horizontally) you'll need a bit more code.
Yeah I've put it on the back-burner for now while I finsih the other bits of the site. I'll just use the same concept as matthijs posted though because it's in a fixed-width side bar.
