Backgournd for certain sideboxes

[gjh42]

You have added a specification for the heading to be that size, so Firefox is only doing what you told it to do.

#searchHeading {
	margin-left: 20px;
	background-color: #CCCCFF;
    height:10px;

Delete the height property and it will show correctly:

#searchHeading {
	margin-left: 20px;
	background-color: #CCCCFF;
	}
