This background shows piano keys down the border on the left side, with a vibrant green background in the main content area.
White background with the ebony and ivory of piano keys decorating the left side.
This left-side border shows aged piece of sheet music fading off into the darkness. Quite a nice subtle and elegant effect!
The subtle waves of music flowing from the left side of this border make for a very subtle and useable background.
I love the way the blue swirls with tiny music notes inside the left border repeat when it's tiled!
