Jesus!!!!, is that your real pic, your real pretty....
anyways back to the point
When i design sites i prefer them to use <div> only with no tables, so that all the sizes are controlled in the stylesheet.
But if i designed a page in photoshop, say a PSD, then sliced it up and saved it as xhtml, it would save the xhtml file with tables as the layout structure where as i want divs? does this help
