Flex, pseudo, js.

For some reason(s), I couldn't get the width of this page to fit well. If I went full width for the html or body the images would look all weird and out of proportion, also if I placed everything in the center, I would had a lot of white space on both sides of the html, even though margin was set to 0. Any tips in regard to this would be appreciated. Other than that, at 1st glance this project seemed easy but I ended up having headaches through out it. Which helped me improved a bit tbh.
