Bootstrap 4 - Modals


Add a stylized tooltip with the Bootstrap tooltip functionality. Bootstrap provides tooltip functionality that allows a stylized tooltip to appear when the user hovers over an item. The text of the tooltip comes from the title attribute.

Basic Modal

Create a modal by using the .modal class and attribute data-toggle = "modal" on a element, like a button or link, along with a data-target = "#identifier" or href = "#identifier" to target a specific modal to toggle.
