Is there really any way to insure that the edge of the right <div> aligns with the edge of the top <div> when using percentages in sizing divisions? It tends to line up in Mozilla but not IE as you can see. Thank you! http://www.charlottes-saddlery.com/about.htm
What you could try is wraping the whole lot in a div and floating the right div to the right.
Then look into using negative margins to position the left column.
Hope that helps
