<p>The CSS background properties allow you to control the background
color of an element, set an image as the background, repeat a background image
vertically or horizontally, and position an image on a page.</p>

<p>
<b>Browser support:</b> IE: Internet Explorer, F: Firefox, N: Netscape.</p>
<p>
<b>W3C:</b> The number in the &quot;W3C&quot; column indicates in which CSS recommendation 
the property is defined (CSS1 or CSS2).</p>
