I read the "boilerplate" in that comment as "basic" meaning "I don't know how to center a div" or "I do not know how to remove duplicates from a collection"

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

[queenkjuul]

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.
