Tooltips allow you to provide hover text, like a glossary. Hover on this text to see an example.
To create Tooltips, select some text, right-click, and choose Insert > Tooltip .
In the editor ribbon, update the Tooltip text with the desired pop-up text. Many elements, such as links, additionally have a tooltip option that can be enabled. Click on the Tooltip button to enable or disable the pop-up.
If you would like all tooltips styled in the same way, you can edit the book's custom CSS and access the tooltips with div#chapter-container [data-toggle=tooltip].
