EXTENSIONS TO HTML 2.0

This document explains the extensions to the HTML 2.0 specification. We're currently working on a document about extensions to HTML 3.0; in the meantime, you can get information about adding tables, backgrounds, and dynamic updating to documents - three important extensions in Netscape Navigator 1.1 and beyond that are being proposed for inclusion in HTML 3.0.

Netscape Communications will continue to work with the appropriate standards bodies, including W3C and the authors of other WWW browsers, in an attempt to have these extensions available in all browsers in the near future. All of the Netscape Navigator extensions to HTML take the form of additional tags and attributes added to the HTML specification and are specifically designed not to break existing WWW browsers.

ADDITIONS

<ISINDEX>
To the ISINDEX element we have added the PROMPT tag. ISINDEX indicates that a document is a searchable index. PROMPT has been added so the document author can specify what message they want to appear before the text input field of the index. The default is of course that unfortunate message:
This is a searchable index. Enter search keywords:
<HR>
The HR element specifies that a horizontal rule of some sort (The default being a shaded engraved line) be drawn across the page. To this element we have added 4 new tags to allow the document author some ability to describe how the horizontal rule should look.
<HR SIZE=number>
The SIZE tag lets the author give an indication of how thick they wish the horizontal rule to be.
<HR WIDTH=number|percent>
The default horizontal rule is always as wide as the page. With the WIDTH tag, the author can specify an exact width in pixels, or a relative width measured in percent of document width.
<HR ALIGN=left|right|center>
Now that horizontal rules do not have to be the width of the page we need to allow the author to specify whether they should be pushed up against the left margin, the right margin, or centered in the page.
<HR NOSHADE>
Finally, for those times when you really want a solid bar, the NOSHADE tag lets you specify that you do not want any fancy shading of your horizontal rule.
<UL>
Your basic bulleted list has a default progression of bullet types that changes as you move through indented levels. From a solid disc, to a circle to a square. We have added a TYPE tag to the UL element so no matter >
