Netscape Extensions

Netscape Communications has developed its own set of extension that go beyond the HTML 2.0 specification. These extensions give you further flexibility over placement of text, images, color of background and text, among others. While theses extension a re nice, it must be remembered that only the Netscape Browser supports all of them. So if you use these extensions, it is important to develop documents that will look good no matter what browser one might be using. Some sites out there on the Web look great through Netscape, but can be unintelligible through other browsers.

The following list is not exhaustive, but covers some of the more commonly used Netscape Extensions. for a more thorough treatment of the subject go to Netscape Communication's own t utorial.
