Working on a site using graphics that i built with fireworks cs4. I set up all my elements and content under a parent container div tag positioned relatively with auto margin. All of my elements inside are positioned absolute and should line up with the container tag. However when I expand the browser window all the elements underneath the tableHeader div shift left and the header remains centered. I am trying to keep everything centered under that header. Don't know what I am doing wrong. The url is http://www.tripleahomerepair.com if you maximize the browser window you can see. Also here is the code.
