Is it possible to attach HTML classes to InDesign objects that export to HTML/EPUB

[Premiopolis]

Looking for way to embed a class or really any tag that that will pass to HTML / EPUB exports.  So far haven't found a way to do so.  Is it possible?

You can do this in Paragraph Styles (see screenshot).

You can also attach a Style Sheet via the ePub export dialogue box or alternatively, crack open the ePub and edit it there.

Thanks Derek, much appreciated.

Extending the above question:

Once you've grabbed an Element ID from an EPUB xhtml file, is there a way to reference back to the corresponding object in InDesign?

The overarching goal here: to be able to mutually correlate EPUB xhtml elements to their InDesign counterpart, in both directions.

So either embed some kind of unique tag in any (or every) INDD object such that way that appears and is accessible in EPUB, and conversely, any Element in EPUB can be traced back to its corresponding INDD object.

Is this possible?
