I'm trying to make a somewhat ghetto sidebar with my basic understanding of javascript. I have a list of links that will appear on the left against a solid color background, then an empty image of that color with a border which will extend to be parallel with the bottom of the center content, which varies between pages. Is it practical to use javascript to get the height of the <div> or <table> tag in the center content and use it to stretch the picture on the left to the appropriate height? If so what's a function I could use to find the height and then to apply it to the image size?
