How does the Hero block work? What are Slides and Fixed Content?

A Hero has two parts. Slides are the backgrounds, and they move: add one for a still banner, or several and they rotate on their own like a carousel. Tick Add copy on a slide to give that one background its own words, which change along with it.

Fixed Content does not move. It stays in one place while the slides change behind it, so use it when you want the same words or buttons on every slide, like a headline or a Watch Now button that is always there. It is off until you press Add fixed content.
