Extending background color of Div in Grid System

Question

Note: I'm using the skeleton grid system.

I am looking to extend the background color of one of my divs to the right, past the 960px container, but I am having no success. Any suggestions?

Solution

One way of achieving this could be to add a new HTML element inside the #support and give it a 100% right padding and 100% negative right margin. Like this:

<div class="one-third column" id="support">
  <div class="inner">
  ...
  </div>
</div>

#support .inner {
  padding-right: 100%;
  margin-right: -100%;
  background-color: #000;
}

Then add a 'page' container with overflow hidden to make sure you don't get a scrollbar.

<div id="page">
  <div class="container">
  ...
  </div>
</div>

#page {
  overflow: hidden;
}

In the first step, the reason I added a new <div> rather than styling the existing #support is that I think it's best to leave <div>s that have grid structure styles alone. We don't want to affect their margins.

Here's a demo.
