Usage
Tooltips are used to help explain an icon button's meaning.
They can also be used with links and images.
Tooltips should be brief and contain a small amount of text. Lexicon recommends a maximum of 280 characters. If your description is longer than 280 characters, please use a popover instead.
The tooltip appears on hover state and disappears on mouse out. This pattern does not exist on mobile, as hover is not a possible state on mobile devices.
Make sure you properly position the arrow to point to the correct interface element. Improper placement can confuse the user.
When possible, try to not overlap other interaction elements in the same component.
Dos and Don'ts
Use tooltips on elements that trigger an action, such as button icons.
