Issue
I have been searching the web for a while now for an answer to my question. I would like to extend a div background-color beyond the div (and the container div as well) so it reaches the width of the browser. Like so http://vinnusal.is/ The problem with the example above is I'm using a padding/margin fix which creates an annoying scroll to the right. I have tried overflow without any luck.
I know this could be done with a container div that is 100% and nesting divs that are smaller. However I would like to use another way if possible, because this is my first shot at a fluid site with all complications that follow.
Thanks in advance, Helgi
Here is the HTML markup:
<body>
<div class="gridContainer clearfix"> <!-- Container -->
<div class="gridContainer clearfix header" id="header"> <!--Header begins-->
<img src="pics/hvitt.png" alt="VFI Logo" name="logo" id="logo">
<!-- Menu Horizontal -->
... irrelevant markup for menu...
</div>
<!-- Header ends -->
<div class="gridContainer clearfix submenu" id="submenu"> <!-- Submenu begins -->
<h1><!-- InstanceBeginEditable name="title" -->Articles<!-- InstanceEndEditable --></h1>
And the CSS:
/* Mobile Layout: 480px and below. */
.gridContainer {
margin-left: auto;
margin-right: auto;
width: 88.626%;
padding-left: 1.1869%;
padding-right: 1.1869%;
}

Solution
You can use the :before
pseudo element with absolute positioning and negative z-index to extend the background color of a contained div the entire way to the edge of the page.
#container {
width: 100px;
margin: 0 auto;
background-color: #FFFFCC;
}
.stripe {
background-color:#CCFFFF;
height: 100px;
position: relative;
}
.stripe:before {
content:"";
background-color:#CCFFFF;
position: absolute;
height: 100%;
width: 4000px;
left: -2000px;
z-index: -1;
}
<div id="container">
<div>one</div>
<div class="stripe">two</div>
<div>three</div>
</div>
