We recommend that you be judicious in using extensions to HTML. They are not part of the current HTML standard so many browsers do not support them, and some of them may not become part of the next standard and so will not work in the future.
That said, presumably you came to this page because you wanted to use them. So...
The primary Netscape extensions are described at Netscape's Web site:
We allow you to insert such HTML tags in the following ways:
Netscape allows a slew of related options, many of which have beenincorporated into the HTML 3.2 standard. The ones AOLpress supports may be edited with the Body Attributes dialog.
Netscape created a special tag called <CENTER> that was incorporated into the HTML 3.2 proposed standard. Currently, Netscape supports only Align Left and Align Center. With AOLpress you can align text in any paragraph, heading, or list using all HTML 3.0 options. Align text to: Left, right, centered, or justified on both the left and right. In fact, you can even align text that wraps next to an image. Not all browsers support all of these alignments.
HTML 3.2 and Netscape use a different mechanism for specifying font size. Netscape uses things like <FONT SIZE=+1> to make the font bigger while HTML 3.0 has a tag <BIG>. AOLpress will generate either one, depending on the setting of "Conform to:" in the preferences dialog.
Tables are part of the HTML 3.2 standard, but again Netscape's version is slightly different. You can create tables with the AOLpress Table menu item. The setting of "Conform to:" in the preferences dialog will control whether default table behavior is like Netscape or HTML 3.2.
To put Netscape attribute extensions on a list: create the list with AOLpress
(Format menu), place the cursor inside the list, and then bring up the Show
HTML window. For example, to set the start value on a numbered list
and the numeric type, type
<OL START=3 TYPE=I>
To change the bullet type of un unnumbered list
<UL TYPE=square>
To change the number of a List line, type
<LI VALUE=8>
HTML 3.2 has slightly different ways of doing many of these.
In general, if you want to insert an extended HTML tag you should bring up the Show HTML window and type the tag directly into the HTML.
