CSS, especially the box model, was not consistent across browsers.
replyTrue. Does not prevent the design from being responsive. Even with no CSS at all a design is responsive unless you specifically choose to break that
replyRight but how would you even display a vertical menu back then? `float: left` was rather bad, so you went back to using tables[0]. Good luck making these responsive.
reply[0]: and to using dozens of images sliced to fit your table cells, for that cool hover effect as well as round corners. :-)
