I decided to make my own framework to gain a better understanding of how it all works and test my CSS skills. I also used it in some of my react projects to test its usability, check this project where I ended up using it.

Have you run into this problem where the footer on your site does not stay at the bottom of the page, even if it is the last tag in your html body. Especially if you are new to web development, you'll run into this problem. There are ways of making sure your footer stays at bottom, but most of those methods have some kind of caveat.
