Structure of the tooltip and how its internal parts are composed. These are the tooltip's semantic parts, so they are also what the classNames and styles objects accept. The trigger is your own element and is not one of them.
Name
Description
1
root
The positioned layer around the bubble and its arrow. It is portalled to <body> unless getPopupContainer says otherwise, so it is not inside the trigger.
2
container
The bubble: background, padding, radius and the text, from title. color repaints it here.
3
arrow
The notch pointing back at the trigger. placement moves it, and arrow={false} removes it.
