Tooltips

Add tooltips built entirely in CSS to nearly any element. Just add a few classes and an aria-label attribute.

In addition, you’ll want to specify a direction:

  • .tooltipped-n
  • .tooltipped-ne
  • .tooltipped-e
  • .tooltipped-se
  • .tooltipped-s
  • .tooltipped-sw
  • .tooltipped-w
  • .tooltipped-nw

Remember, aria-label and tooltip classes must go directly on <button> and <a> elements. Tooltip classes also conflict with Octicon classes, and as such, must go on a parent element instead of the icon.
