Abstract:

The question of whether or not to use frames within a Web site's design can be a hot topic of debate. Many people don't like framed Web sites because they 'get stuck in someone's frames,' they can't bookmark a particular page within a framed Web site, the search engines don't list their Web sites, and some browsers can't read framed Web sites at all. Clearly these are legitimate problems. This article's intent is to help clarify some of the advantages and disadvantages of using frames and provide resources for further information.
