Hello, I'm trying to understand CSS in general and some of the CSS used by a downloaded prebuilt theme which has a Style.css. Is it using CSS 2.1? My VS 2010 environment shows the style.css as CSS 2.1 and some of the properties have a green squiggly line under them with a hover message of "Validation (CSS 2.1): 'text-shadow' is not a known CSS property name". Those are CSS 3 properties. When I look at the body element in the Style.css, it seems to have two color properties for the background. It has the "background:#7692B9;" and then the "background: #bbc9dc url('img/background.png') top repeat-x;"body{font-family:Tahoma, Verdana, Arial, Helvetica, sans-serif;font-size:12px;background:#7692B9;color:#3A4045;background: #bbc9dc url('img/background.png') top repeat-x;} What is the purpose of having the background color property in both places when in fact the image "url('img/background.png')" for the background has it's own color? Or is my interpretation screwed up. Any help would be gratefully appreciated. Thanks,Tony
