Dynamic HTML in Netscape Communicator

Netscape's implementation of Dynamic HTML is more limited than Microsoft's, and you can find information about it at http://developer.netscape.com/docs/manuals/communicator/dynhtml/index.htm.

Here are the key elements of Netscape's version of Dynamic HTML:

• Document Object Model (DOM). Microsoft's DOM is more extensive than Netscape's is, as we've seen in the previous chapters. Although you can access many elements in code, the support is not as full as in the Internet Explorer.

• Dynamic content. Like the Internet Explorer, you can change the content of elements in the Netscape Navigatorbut the options are more limited. Instead of using methods such as insertAdjacentHTML and insertAdjacentText , as well as properties such as innerText , innerHTML , outerText , and outerHTML , Netscape Navigator supports only the innerHTML property.

• Absolute positioning. As in the Internet Explorer, you can use style sheet positioning to move elements and even create animated effects.

• Downloadable fonts. In the Netscape Navigator, you can download fonts from the Internet and install them in your web pages, using downloadable fonts. However, these are not in widespread use.

As you can see, Netscape's implementation of Dynamic HTML is more restricted than Microsoft's. That means that many of the topics in this and the next chapter will apply to the Internet Explorer only.
