Use a default popover in Bootstrap by adding the data-bs-toggle="popover" attribute to an element. Set the popover content with the data-bs-content attribute.

Set popover directions in Bootstrap with classes like data-bs-placement="top" or data-bs-placement="bottom". These classes control where the popover appears relative to the element.

Apply a custom color to your Bootstrap popover using the data-bs-custom-class="popover-*" attribute. This class sets a custom background color for the popover.
