XHTML CSS background not filling entire div
I've got a page that has a background color for the main container, but for some reason, the color ends just below the header div. The page and the CSS validate in the w3 validators, though, and I have no idea why and I've tried several different fixes.
CSS
body{
margin:0;
padding:0;
line-height: 1.5em;
background-color: #e5e5dc;
color: #000;
}
#maincontainer{
background-color: green;
width: 98%;
margin: 0 auto;
border: 1px solid black;
}
#topsection{
background-color: transparent;
height: 90px; /*Height of top section*/
}
#logo{
background-image: url();
text-align: center;
margin: 0 auto;
width: 100%;
}
#contentwrapper{
float: left;
width: 100%;
background-color: transparent;
}
#contentcolumn{
margin-right: 230px; /*Set right margin to RightColumnWidth*/
}
#rightcolumn{
float: left;
width: 230px; /*Width of right column in pixels*/
margin-left: -230px; /*Set left margin to -(RightColumnWidth) */
background-color: transparent;
}
#footer{
clear: left;
width: 100%;
background-color: transparent;
text-align: center;
padding: 4px 0;
border-top: 1px solid black;
}
.innertube{
margin: 10px; /*Margins for inner DIV inside each column (to provide padding)*/
margin-top: 0;
}
.error{
background-image: url("images/misc/scroll.jpg");
background-position: top left;
background-repeat: no-repeat;
}
a:link, a:visited{
color: #000;
text-decoration: none;
}
a:hover, a:active{
color: #000;
text-decoration: underline;
}

You are floating #contentwrapper which takes it out of the document flow so #maincontainer no longer contains it.
To contain it, you need to give #maincontainer an overflow attribute (auto should work).
FYI, adding borders to your elements are a good way to debug things like this.
If I understand correctly, this is a well addressed question. See CSS 100% height in ie or http://www.tutwow.com/htmlcss/quick-tip-css-100-height/
