I'm using CSS to style a page.  The page has a heading block, two columns, 
and a footer.

Here's the css for the two columns:
#leftstuff {
  float: left;
  width: 44%;
  margin: 0;
  padding: 1em
}

#rightstuff {
  width: 44%;
  margin-left: 50%;
  padding: 1em
}

Using this I have to have two divs in the html.  So I have to balance the 
two columns using my skill and judgement - a sub optimal approach.

Is there any way I can get the two columns to 'flow'?
