Parallax scrolling and fixed footer code causing width issues
<p>I bolted together some bits of code. One is parallax scrolling, and the other is a piece of fixed footer code I found here: <a href="http://codepen.io/madshaakansson/pen/CGjcH" rel="nofollow noreferrer">http://codepen.io/madshaakansson/pen/CGjcH</a></p>

<p>Though after bolting it together and fixing a few issues, I now have a problem with different widths. The header is a different width to the footer, and main content doesnt span the whole width of the page. I have tried adjusting the width of the content css to 100%, which made the main content span the whole width, but it ended up breaking the footer.</p>

<p>I am not sure what I need to change to make these different bits of code work together. Any advice would be greatly appreciated. </p>
