One thing to be aware of is PNG color-shifting in IE. If you try to use a non-transparent PNG with non-square edges and "fill in" the background color, then place it inside a region with a CSS background-color, they may not match up exactly, even with supposedly the same hex values. Even when opening the PNG in Photoshop, it will show the PNG as having the correct hex value. In these circumstances, it's best just to use a 10x10 pixel flat color PNG as your background-image for the container region. Don't use smaller tiles than 10x10 (i generally go for at least 20x20 myself) as this puts a lot of strain on the client and you may get strange rendering glitches, especially on older machines. Of course, similar problems arise with JPEGs, especially when saved at low-quality, but at least with JPEGs you can validate the hex value shift in Photoshop. david ______________________________________________________________________ css-discuss [EMAIL PROTECTED] http://www.css-discuss.org/mailman/listinfo/css-d IE7b2 testing hub -- http://css-discuss.incutio.com/?page=IE7 List wiki/FAQ -- http://css-discuss.incutio.com/ Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
