A deprecated tag is one that is being phased out and at some future point will no longer work on new browsers. You are encouraged to avoid using deprecated tags. You should use either newer tags that do the same operations or do some of your work using styles. This can be a little bit more complicated at first and involves learning how to use styles and style sheets, but the advantages outweigh the difficulties. Most properly designed web pages use styles for a lot of their design, and avoid the need to use deprecated tags. It makes your pages and sites a lot easier to maintain and means that your pages will function well on most browsers into the future.
