The site is local at the moment.
Basically the <body> is set at 100% height, then I have a div set at min-height: 100%, position: relative and a slider div set with position: absolute and a z-index: -1. I have a couple of divs that contain content that floats over the slider.
All of the above works correctly. The footer is basically locked to the bottom of the browser window and everything grows correctly if the browser size is increased except the slider images won't continue to fill vertically down to the top of the footer. They size up horizontally correctly increasing with the screen size.
