If you are running lgsl blocks on your site and u want to change the background color to integrate with your template you will have to edit the lgsl_style.css file. There is a small typo in the dl that u must fix in order to do this.
body
{
margin:0px;
color: #c0C0c0;
color should be background-color
it should look like this:
body
{
margin:0px;
background-color: #c0C0c0;
