The sidebar content will be displayed in other browsers at the top of the body of the web page. Many times, sidebars in the WebTV interface have a colored background. To provide a colored background for your web page, create a table the same size as the sidebar and set the bgcolor attribute for that table.
Possible values are center, left, and right.
The default value for align is left. The value for width can be a whole number of pixels or a percentage of screen width. The default value for width is 0.
