The contents of the divs are filled by a program. Sometimes these divs have no content. IE7 displays
them as I want - an 'empty' section of space of the specified width. IE8 and FF ignore the width, however,
and render the divs as 0px wide.
What do I do to force the empty divs to be displayed at the specified width?
If I put an &NBSP; in the empty divs, they are rendered the way I want, but this is hokey.
