Using built‑in behaviors

The behaviors included with Dreamweaver have been written to work in modern browsers. The behaviors fail silently in older browsers.

Note: The Dreamweaver actions have been carefully written to work in as many browsers as possible. If you remove code from a Dreamweaver action by hand, or replace it with your own code, you may lose cross-browser compatibility.

Although the Dreamweaver actions were written to maximize cross-browser compatibility, some browsers do not support JavaScript at all, and many people who browse the web keep JavaScript turned off in their browsers. For best cross-platform results, provide alternative interfaces enclosed in <noscript> tags so that people without JavaScript can use your site.
