Help! I can't figure out my boostrap error!

At least I think it’s a bootstrap error. Everything was working fine when I opened it on my phone and I went back in to clean up a couple of things and now it’s no longer mobile responsive. I went through all my closing tags and I don’t think I’m missing any. I’ve been going through it for hours and watched Youtube videos on bootstrap but I still don’t see what I’ve done wrong. Anyone?

Thanks in advanced!

I figured it out. Haha. Disregard!
