Quick Reference: Adding Animation

Animation is tricky to use but, if done tastefully, can enhance your site. Animated GIFs are the simplest and most common forms of animation on the Web. However, you can also add animation through Java applets and Flash animation. HTML animations such as <marquee> and <blink> are discouraged because they are presentational elements. In the transitional world of XHTML 1.0, they are discouraged; in the strict world of XHTML 1.1 and even stricter world of XHTML 2.0, they are not permitted. The following table lists some of the basic code you will need to add animations to your Web pages:
