My page isn't mobile responsive

Site: All the Feels

Problem: When I test the site responsiveness in Dev Tools, all appears fine. The site appears responsive in mobile views and tablet views. However, when I test it on my actual mobile device or tablet, this is not the case. The section1 background is set to cover the entire background. In tablet and mobile, it appears zoomed in. Can someone please take a look and let me know what I am doing wrong? Thank you.
