Site Looks Zoomed in

Site URL: https://www.deka.solutions/

Hey everyone, 

Recently viewed the site I created and everything is zoomed in. It is like the margins went to 0px and I do not know why? A good example is on deka.solutions/giving if you scroll down the the video animations, you will see that the video is zoomed in so much that it goes out of the code block it is supposed to be in. Here is a screenshot if what I am talking about.

Can anyone tell me why this is and/or how to fix it?

I'm experiencing the same thing on two sites that I manage. It's like the Content Width of every section was changed to "L" to span the entire browser window. Noticed it this morning.

same thing here both sites 90% of the pages were switch to L what is going on?

anyone get any answers to the mystery width change to L?
