Mention all the various alignment options in documentation
Created by: Sire
There is a lot of confusion about alignment in bootstrap.
I suggest the page about vertical alignment also mention or link to all the other options for alignment. Especially since auto-margins usually work better now that Bootstrap 4 is flexbox by default.
At least add a link to auto-margins.
Even better, use some text from this excellent stack overflow post by Zim.
"There are many different approaches to vertical alignment using: auto-margins, flexbox utils, or the display utils along with vertical align utils. At first "vertical align utils" seems obvious but these only work with inline and table display elements. "
Thanks!
