Huddle landing page (junior) using HTML and CSS

Hello everyone !

I tried (for a long time) to put the same height for the 3 middle sections, I couldn't figure how to do it because of the pictures, sooo I gave up x)

I asked for help about that on Discord, someone replied saying that I have loads of position relative, transform, many width in % etc and that it is nearly impossible to debug my code. I put the width in % because of the responsive ? Isn't a good thing ? Is it because of all those things that I can't put the same height on my sections ?

Feedback will be greatly appreciated :) Thanks in advance
