tiene (ademas de ser un excelente editor CSS y XHTML)una opción para esto y lo llama
orphan classes
El texto a continuación está extraído del manual de este programa:
Cita: 9.1. Orphan Classes
The Orphan Classes report displays style sheets which contain definitions for classes that
aren't used in any HTML documents which link to those style sheets. For example, if your
style sheet contains the class .warning but none of the HTML documents which link to that
style sheet contain class="warning", then .warning will appear in this report.
If any orphan classes exist in the current site, this report will show an expandable list of
style sheets which contain the orphans. Clicking a style sheet in this list will display its
contents in the read-only editor. To edit the style sheet, simply click the Edit toolbutton to
the left of the editor.
When a style sheet is expanded, a list of its orphan classes will appear below it. Clicking an
orphan class will locate it in the read-only editor. If that class is used in more than one
selector (ex: .caption, h2.caption, h3.caption), then the "Next" and "Previous"
toolbuttons to the left of the editor will be enabled so you can quickly navigate through
each usage.
a ver que tal te va.
