How do I display a background image in my sidebar gadget?
When your gadget is docked, it displays a background image, which is allowed to be alpha-transparent.
This is controlled by the CSS for your gadget:
body {
background-image: url(GadgetBackground.png);
background-repeat: no-repeat;
}
Your background should be 130 pixels wide when docked, but the height can vary. The size is controlled by another CSS rule:
body.docked {
width: 130px;
height: 113px;
}
Note that this assumes that you’re using different class names for the docked and undocked state of your gadget.
The background image should be a .PNG file (because you’ll want alpha-transparency).
