I have a left column with a background image and another background image for the body so it fills the rest of the screen. I have content area to the right of the left column that will extend vertically past the browser window. With the left column set to 100% height, once I scroll down the background image for the left column will not extend past the original size of the screen. Is there a pure css way to have the left column extend past the original height of the browser window, to match the content area?
