sideboxes slightly off

[stevesh]

You also have 20px of padding here:

.leftBoxHeading, .rightBoxHeading {
margin: 0em;
background-image:url('../images/box000.gif');
background-repeat: no-repeat;
padding: 20px
}

Your div boxes do line up - the background images you have created for the columns include space at either side - giving the impression they are indented...

you could either edit those background images... or change the header to allow for those gaps...
