Make it full screen. The sidebar on the left is curvy at the top because I've used CSS to include that image at the top. It is also set to 200px wide using a CSS rule.
Now resize the window horizontally. Make it smaller in width. See how the sidebar shrinks and we lose that nice curve at the top? How can I make it always 200px wide, and simple use scroll bars when the window gets too small?
