When you use a Web page template, Word will make features that are not supported by your target browser unavailable so that you don't have to worry about how your formatting will look in a Web browser. Add a theme, insert link bars, and use frames to make your Web pages more dynamic and engaging. To apply formatting quickly to several pages, you can attach cascading style sheets (CSS).
