On my products page I have set the layout to be 2 columns with right bar. What I am trying to do is make the col-right sidebar border height to be the same as the col-main. I have tried doing this in the CSS and have been only able to do it by manually setting the pixel height. Obviously the main class and the col-main class heights are set by the content. I was just wondering if there is a way to set the col-right sidebar class border height to automatically be the same as the col-main class?
