I just created this site - http://luna-ext.di.fc.ul.pt/~pqsi020/ I tested it with Firefox and IE. But with IE6 at bottom appears some junk but i can't discover were is the problem - can someone help me?
The H2 are rendered with sIFR but i tested it with http://www.snugtech.com/safaritest/ and the result was that the headers didn't showed up. Could someone see if with mac it works?
There is a problem with you CSS .seccao { PADDING-RIGHT: 0px; PADDING-LEFT: 200px; FLOAT: left; WIDTH: 100%; PADDING-TOP: 200px } remove FLOAT:left: from here it wil fix you problem.
Also <DIV class=seccao id=tarefas> you can't do that. Use either class or ID not both it causing some problems too. Also all you HTML tags in Uppper case which is invalid XHTML. It will not validate it should be in a lower case.
