Placing div below an <iframe> video

I’m trying to place more content below my video I added in my page. But the div i add below the iframe video gets put behind the video, so i cant see it. I want all my content after the iframe video to go below it and not be obstructed by it. I’ve tried adding in a position: relative and position: absolute to the div below it and the iframe videos div but i’ve had no success. Any suggestions here? Thanks!

The code for this project i’m working on is on my codepen account (same username as this site) titled “Product Landing Page”.

Will be helpful if you add a link to your demo.

cant add links yet, says i’m too new
