The Editor recognizes JavaScript code in stand-alone JavaScript files
as well as in HTML, RHTML, and JSP files.
The visual CSS editor allows you to edit CSS rules and preview the results.
JavaScript Debugger
View and navigate source artifacts, and add and delete breakpoints in JavaScript code
be it in HTML files, JavaScript files, or generated URL sources.
You can view window and frame structure, view and navigate the JavaScript Callstack,
view local variables, set and delete watches.
The debugger also allows you to view (static) browser DOM in the IDE.
The JavaScript debugger requires the Firefox 2.0.0.X browser
with the Firebug 1.1beta plugin, or Internet Explorer (6 or 7).
You can also debug JavaScript code in Java EE and Ruby projects
(to debug client sessions and for source mapping).
