Size Change

My site is baaramewepasturedlamb.com I have a problem with the website when a user tries to change the size of the window. At one certain position it breaks, but if you keep going smaller it gets fine again. Looks fine on smaller screens also.
I have changed some css using a child theme, but don’t know what php even controls that.

Also, was wondering how the logo and container worked. Since making container width larger pushed logo more left. When screen is made smaller the logo centers and I would like it to stay left.
