			<h2>(Almost) Static Background</h2>
	        <p>This section has a background that moves slightly slower than the user scrolls. This is achieved by changing the top position of the background for every pixel the page is scrolled.</p>

	            <h2>Multiple Backgrounds</h2>
	            <p>The multiple backgrounds applied to this section are moved in a similar way to the first section -- every time the user scrolls down the page by a pixel, the positions of the backgrounds are changed.</p>

	//inertia - speed to move relative to vertical scroll. Example: 0.1 is one tenth the speed of scrolling, 2 is twice the speed of scrolling
	//outerHeight (true/false) - Whether or not jQuery should use it's outerHeight option to determine when a section is in the viewport
