he theme is a set of colors, fonts, and decorative elements that provide a consistent appearance to your site. A site comes with a set of themes that enable you to quickly change the appearance, based on your organization's needs.

Applying a theme does not affect the layout or content of your site. It also does not change the theme of any specific pages that you applied a theme to by using a Web design program that is compatible with Microsoft Windows SharePoint Services, such as Microsoft Office SharePoint Designer 2007.
