TIL that in CSS, if you want to position an item relative to its parent, you tell the parent to position relative and the child item to position absolute. 🤷 Noob life. (Mostly tweeting so I have a better chance of remembering next time I need it.)

The CSS box model is very simple and intuitive but you need to read it first 🤪BTW z-index also doesn’t work if you don’t have position set on the element.
