I am working on a template for joomla , not that it matters in the end. I am trying different 3 column layouts.... In this particular layout my header (#mast ID) has a bottom margin in FF and I am not sure why. I am also curious why the left column will flow behind the text but the right margin does not.....i never quite understood that. the template test site is at www.mychemistrytutor.com/index.php it is hidden behind a .html file thanks a bunch
