Setting margins to 0px either with 'margin-top', 'margin-bottom', etc. or the 'margin:' shortcut has no effect on the BODY element. Works fine on other block elements (ie. paragraphs touch when margins are set to 0px). The URL above points to a page with the margin set to 0px on all four sides of the BODY element, yet there is a white gap on the canvas around the colored element. In this example, the blue paragraph should be touching the browser chrome. Adding the nonstandard marginwidth and marginheight attributes on the BODY tag give the desired effect...

the default style rule for BODY in the ua.css has this in it: padding: 8px; so setting the margin to 0px did work, but the BODY isn't using a margin to achive the boundary around it. we should be able to convert back over to using a margin once the rendering issues with the HTML area inheriting the BODY's background appropriately are fixed. Since troys on that one, I'm reassigning it to him.

Changed ua.css to use margin and not padding
