Does anyone know how to centre a div?

Last time I looked there were at least seven ways to do it.

I think "How to center a DIV" was at the top of HN way more times than it should have been :)

margin: auto, or flex align-items/justify-content are my go-tos

Flexbox, mate

Well both of them are easily retrieved from web search, it's not a problem if you forget one or two. I'll probably need some refreshment if I want to implement bubble sort again.

The topic refers to being on an airplane without internet....
