I'm guessing that you're referring to the australiansmallbusiness.net site.
There are a few things between your style tags that need to be fixed.
You neglected to add the ound sign "#" before the hex code specifying your font color. It should read "color:#222222"
Additionally, it's probably better to specify the page background color by applying the style to the body tag instead of in a class called ".main".
Inside the style for the body tag, add "background-color: #F4F4F4;" Save the file and reload the page in your browsero
HTML Code:
<style type="text/css">
body { color: 222222;
font-family: Arial, Helvetica, sans-serif;
font-size: 10px;
}
.box{
width: 750px;
text-align: left;
border: 1px solid #6BB300;
background: #FFFFFF;
}
.main{
text-align: left;
border: 1px solid #6BB300;
background: #F4F4F4;
}
</style>
