Content container is spilling into part 2

Hello everyone, I am having trouble with my responsive website. At the most minimized window my content container starts to spill into part_2 of y website. Here is the link to my codepen

You don’t responsive less than 320px, in 2018 is not possible to have a mobile less than 320px

I am still having a problem where the content is spilling into part 2 of the section.

I believe it has something to do with that .cover-all class. Everything is wrapped into it, so there’s nothing to contain the elements within the section that has the background image.You could try moving the part_2+ sections of the code outside of that class so that only your content and image containers are inside of it. Then you could change the margins of part 2 so it doesn’t overlap possibly.
