<p id="box">
	This demo attempts to demonstrate how the CSS box model works. Try adjusting the <code>width</code>, <code>height</code>,
	<code>padding</code> or <code>border</code> and observe. You may also try using <code>box-sizing</code> 
	to see how it changes the way the box model works. The background grid is at 10px intervals and the darker lines at 50px intervals.
