This question comes up periodically, so I made a cheat sheet based on the latest information I could find from Apple (last updated in 2016).
When you get a sec, please look at that post in dark mode. It’s very hard to read.
Will do. It also has problems on iOS Safari with word wrapping (which is something I’ve been trying to solve for a couple of weeks now).
Should be fixed now, thanks for pointing it out.
