Broken Solution, Help Please!!!

What are you most proud of, and what would you do differently next time?

Okay so this challenged sucked. I'm really lost when it comes to the images and for some reason my page keeps breaking out of the viewport and creating a horizontal scroll. I even tried to re-write the entire challenge over again and still got the same issues so I'm pretty fed up and just going to come back to it another time.

What challenges did you encounter, and how did you overcome them?

a lot.

What specific areas of your project would you like help with?

I would love any advice on why the hero images and the 4 image group could also be ruining the viewport width and what I could be doing wrong with my css. Honestly at this point I'm so lost so I don't know how to even ask for the right help.

Thanks for any advice!
