Standards-based development is a recent movement in the web design community that seeks to standardize the way websites are built using the World Wide Web Consortiums (W3C) published specs. Essentially, this involves using well-formed HTML for content, cascading style sheets (CSS) for presentation and avoiding proprietary technology like browser-specific filters and HTML tags.
While this may sound complex, its simply a better way of doing things. Sites built with standards tend to perform better across different browsers and platforms (including hand-held devices like cellphones), are more easily indexed by search engines and lend themselves to accessibility.
