Appropriate menu labels for sidebar menu controlling background of component

I am working on the app which has the following sidebar element which does two things

  1. Size - It contains for controlling the background size of an element's background image. As per https://tailwindcss.com/docs/background-size/ this can be auto, contain and cover.

  2. Movement - It allows the user to specify whether or not the background should be parallax or fixed.

I do not think any of these terms are user friendly. I was wondering what would be the best way to communicate them to the user?

P.S. please ignore the typo, it should have been fixed now.
