One thing that I have learned in over a decade developing web sites is that the Net is continually changing, and to keep up you need to change with it. One of the more recent developments in web design is the use of CSS and semantic markup. CSS and semantic web design has several benefits: clarity in code, browser and other web-enabled devices compatibility, seperation of content and presentation, smaller burden on bandwith, and better visibility to search engines.

supply information for Web search engines using web crawlers. This could be machine-readable information about the human-readable content of the document (such as the creator, title, description, etc., of the document) or it could be purely metadata representing a set of facts (such as resources and services elsewhere in the site). (Note that anything that can be identified with a Uniform Resource Identifier (URI) can be described, so the semantic web can reason about people, places, ideas, cats etc.)
