About cascading style sheet compatibility

Microsoft FrontPage enables you to design your web site for compatibility with an array of different browsers and technologies, among which are cascading style sheet (CSS) features.

If you design a web site for compatibility with a Web browser that doesn't support CSS, the commands that use CSS will be unavailable on menus (that is, they will appear dimmed) when authoring web pages. This is to prevent you from accidentally using features that won't be compatible with the Web browsers used by your desired audience.
