title: Make left and right screen widgets stay in the same place while user scrolls down the page with spacebar
body: <p>I have webpage with a large height attribute which displays products.  I want the user to hit space bar to move the page down to view more products, but I need my screen widgets (shopping cart &amp; categories) on the left and right to stay in the same place on the screen.  And I don't want to use scrollbars.  I assume this is a javascript request, can someone point me to a good resource for this?  </p>
