Hi. I'm taking my very first shot at site building using Photoshop
CS3, and finding it quite easy and useful in getting the exact look I
want. There's just one remaining task....getting the background layer
(just a plain solid color) to have a variable width for anyone using a
screen res wider than 1024. Currently, if I look at the page on a
larger screen, the color stops at 1024 and the space to the right is
just plain white. I want that color layer to fill the browser window,
no matter how wide.

Do I need to somehow convert that layer to "CSS" (which I know nothing
about) to get that variable width? Is CS3 capable of getting this
result? [I'm not going to buy additional software for this, since I'm
not looking for a career in web design...I'm just building 2 sites for
myself and that's the end of it.]

Many thanks!

Rudy
