more color required

[hamfast]

Hello people

I'm wondering if you could help. I've included the css of my website - could anyone tell me how best to alter it. The web content is concentrated in the middle third of the screen which I'm happy with - but the outer thirds could do with some colour because currently they are plain white.

Is there an easy way to achieve this that will work with all browsers?

Thanks
H

I see you tried to wrap your content in code tags, but the posts use BBC code not HTML so your <code> needs to drop the <> and use [ ] instead.

As for your bg-color you change it here:

body {
font-family: arial, tahoma, helvetica, verdana, sans-serif;
font-size:12px;
cursor:default;
color: #aaaaaa;
background-color:#FFFFFF;
}

Use Hex colors for best browser support, #FFF is white, #000 is black... you can find complete lists on google for Hex Color Codes as a search.
