Close button

A generic close button for dismissing content like modals and alerts.

Example

Provide an option to dismiss or close a component with .btn-close. Default styling is limited, but highly customizable. Modify the Sass variables to replace the default background-image. Be sure to include text for screen readers, as we’ve done with aria-label.

Close button - 图1

html

  1. <button type="button" class="btn-close" aria-label="Close"></button>

Disabled state

Disabled close buttons change their opacity. We’ve also applied pointer-events: none and user-select: none to preventing hover and active states from triggering.

html

  1. <button type="button" class="btn-close" disabled aria-label="Close"></button>

White variant

Change the default .btn-close to be white with the .btn-close-white class. This class uses the filter property to invert the background-image.
