Please see the synopsis of LibWeb::HTML::Default to see how those HTML constructs can be displayed.

This class provides several common table templates for HTML display. This allows Web application designers focus their efforts on the logic of programs; while Web page designers spend their efforts on customizing this default by ISAing this class, say LibWeb::Themes::Futuristic, and writing different themes. A sample MyTheme.pm is included in the distribution for your hacking pleasure.

The current version of LibWeb::Themes::Default is available at

   http://libweb.sourceforge.net

Several LibWeb applications (LEAPs) have be written, released and are available at

   http://leaps.sourceforge.net

Variables in all-caps (e.g. SITE_BG_COLOR) are those variables set through LibWeb's rc file. Please read LibWeb::Core for more information. Method's parameters in square brackets means optional.

This release does not provide a lot of table templates and only a default theme is available. Hopefully more people can write more themes for LibWeb and make them available at http://libweb.sourceforge.net.
