I have a centered wrapper with a background image that partially flows over to the main bg...
The problem is that the centering judders around between 1 pixel depending on whether the window size is an odd or even number of pixels (I assume that's what's going on.. it makes sense for that to happen).
I am just not sure if there's any way for the centered div to always line up precisely with the main background based on the nature of centering things.
the code i have is like so:
background: #e1e1e1 url(images/bggrad.gif) repeat-x top;
background: url(images/bg.jpg) top no-repeat;
margin: 108px auto 20px;
background: #FFF url(images/bg.jpg) -172px -108px no-repeat;
Hope that made sense!
