A friendly reminder to don't change the z-index like gambling with the highest value, if it doesn't work as expected check the stacking context of the early elements in the hierarchy.
`position` is just one of the attrs creating stacking contexts. e.g. check `isolation`. #webdev

This is basic stuff for a lot of developers but is often misused anyway. Yes, read this whole thing first or continue gambling. 😉
