Any way to find orphaned styles?

Monaghan · 08-19-2026, 06:54 AM

Is there any way to find style classes that are present in the html pages, but are not defined in the stylesheet? I'm thinking specifically of overridden InDesign styles from print files, but this would be useful in a bunch of cases.

A forum search didn't yield any answers, but perhaps I didn't use the right terms.

Have you tried Sigil Reports?

There is a Classes in HTML Report that searches the html for class attributes creating a list with a field indicating if that selector was matched in a stylesheet. You can export it to CSV to examine in detail if so desired. It should be sortable on that field.

You can also try the cssUndefinedClasses plugin which reports any styles in the html files that do not exist in a stylesheet or in the html file.

Excellent. Covered on all fronts then! Thank you.
