Close Button

The close button is a small, accessible "x" for dismissing alerts, toasts, modals, offcanvas panels, chips and list items. Always set an aria-label, use data-bs-dismiss to close Bootstrap components, and place it on dark surfaces with data-bs-theme="dark".

1Basic close button

A plain .btn-close; always give it an aria-label.

2Disabled

The disabled attribute fades the button and blocks clicks.

3On dark backgrounds

Inside data-bs-theme="dark" the icon turns white automatically.

4In an alert

data-bs-dismiss="alert" removes the alert when the close button is clicked.

5In a toast

The close button in a toast header uses data-bs-dismiss="toast"; the button below shows it again.

6In a modal header

A static modal preview: the close button sits at the end of the header.

Positioned in the top-right corner of a card to dismiss a tip.
