Crop image on smaller breakpoints

Hello all,

I’m very new to Webflow. I’m looking for a way to crop (not just resize) images on the mobile breakpoint.

The image is large on desktop & tablet, which is fine but on mobile I want to crop out the bottom third of the image.

For now it’s set as a background to the section. Is there a way to crop it like that or do I need to add the image (instead of having it as BG) and if so how would I then crop for mobile?
