Is this because of Chrome? Every website is different now

Forgive me, if wrong flair

I use Chrome on my tablet, a Samsung one, if that's important, and the past few days, EVERY website I use looks completely different now

YouTube, Reddit, even Google, looks freaking weird and annoying now. It feels like someone messed around with all my settings, and dimensions and stuff

What on earth is going on? It's extremely obnoxious, and unnecessary. Who in God's name wanted this? This is the worst update I've seen in years, anyone know how to fix this?

If not Chrome, would appreciate it someone can point me in the right direction
