Google released the technology acquired by JotSpot as the new Sites tool in the Google Apps suite. The Sites tools provides the interface you see here for modifying the appearance of your site, using pre-defined themes as a starting place, allowing you to modify the layout of content modules in the left column, and the colors used in the layout.

1. Selecting a theme.
2. Modifying page elements.
3. Configuring a module.
4. Setting colors.
5. Setting background images.
6. The modified site appearance.
