Having Issues with multiple background images

Hey gang. I’m having issues with my portfolio objective. I have unique images for each section (single page). The first two sections are fine but the third image takes over the second instead of displaying beneath. ??

Portfolio on CodePen

This is far from finished. Just wanting this fixed before I move on.

Several lookers but no advise.
I appreciate any help.
Thanks !!

I found the answer on my own. Added the following to each CSS background entry:

background-repeat: no-repeat;
overflow: hidden;

Thank you for this. This is the issue I’m facing as well. I’ll give it a try myself.
