Sidebar Reference Panels

Netscape 7 and Mozilla contain a sidebar panel (F9). This panel has a range of
utilities, such as search, with which the browsers ship, but there are also additional
sidebar panels that individuals have created. Some of these panels are extremely
valuable for Web designers to have as they offer immediate, in-browser access to
aspects of design.
Sidebar panels of immediate relevance to Web designers include the following:
CSS 2 and CSS 2.1 sidebar reference panels (available in French, too)
HTML 4.01 sidebar reference panel
Document Object Model 2 (DOM 2) sidebar reference panel (also
available in French)
JavaScript sidebar reference panels and guides (multiple versions)
XSLT 1.0 (Extensible Style Language with Transformations) sidebar
reference panel
Each of these panels is available completely free and install instantly. Once in
place, the panels act as references by both the information they contain within
them and the fact that references are linked to the specifications they represent.
If I’m working on a site using CSS 2, and I want to know how to use a certain
property, I simply open the CSS 2 side panel (shown in Figure 1-11), find the
property in question, and click the reference. My browser then takes me directly
to the topic within the specification
Currently, sidebar panels can be downloaded from the Netscape DevEdge site,
http://devedge.netscape.com/toolbox/sidebars/. It’s unknown at this
time whether AOL will continue to host that site indefinitely. If you cannot resolve
the site, visit the Web Standards Project, www.webstandards.org/, which has
committed to ensuring the location of these panels will always be made available.
