You can delete a style by right-clicking it and clicking Delete.

 

 

This will, however, deletes any styles that were based on it.

 

As for the text, it will be returned to the style that the deleted style was based on. If there is no such style, it will be returned to the normal style.

 

Let’s look at the sample document we’ve been using. In that document, we had Heading 1. We modified that to create Heading 1 + Centered. We then modified that to create Heading 1 + Centered + Blue. If we delete Heading 1 + Centered, Heading 1 + Centered + Blue will be deleted as well, and our text will return to Heading 1 style.

 

Here’s a sample diagram that may help you out:

You can see how Heading 1 + Centered + Blue is dependent on both its preceding styles. We could delete that style, however, without affecting the other two.
