Ok this is driving me up the wall. I know it has be be such an easy fix but what is stoping me from having auto height. I know its a lot of code and I know that there is alot of things I can do to it to make it better and smother. Thanks for the help in advance! If it makes any difference, this site was written in HTML5 and I used some CSS3 attributes
