What does the 'sticky nav' plugin do that is different from doing it with CSS (fixed position, z-index)?

I think I'm learning things out of order. I learned to do the sticky nav plugin, and now I'm learning how to basically do the same thing with CSS. Why did they make the sticky nav plugin if it's so easy to do it without JavaScript?

I guess one reason is because JavaScript allows you to add animations on scroll, which you can't with only css.

It is easy to do with css and you can add some basic animation etc, but using JavaScript plugins allows you to do extra things like tell the nav to become sticky only after you've scrolled past a banner, or start at the bottom of the window (on screen but below a banner) and then smoothly scroll to become a fixed top header. Also it used to be harder to do everything with css, and still can be if you're trying to support older browsers.
