<h1>A Simple Three Column Layout</h1>
<p><strong>Step x - bold text here...</strong> In this example, we are going to use
absolute positioning to create a three column layout, which is also a very common page
layout you will see on the web. This format enables you to follow the widely-adopted
convention of placing navigation in a vertical "stack" on the left side, and use the right
side for things like testimonials, promotions, ads or other links.</p>
<p>In this design, we'll fix the width of the side columns and let the content column
fill the rest of the browser's width.</p>
</div>
<div id="rightcolumn">
<p>This is temporary filler for the right column. We'll put something more interesting
in here later.</p>
