Putting a background image inside a shape with pseudo-elements

Question

I have a slanted div and I was wondering how I could get an image within the div that would fill it entirely. For example, it is a rectangle but there is a triangle added to each end to create the "slanted" part of the shape. I would like separate pictures for each div (so to fill the entire purple space), so being able to have different. Thanks for your help in advance.

Answer 1

I only did left one. Notice I added a background image to the "main" div element(<div class="rr rr-left">) and for the triangle part instead of the color purple I used transparent. Hopefully it's what you needed.
