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.

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

disabled state

Disabled close buttons change their opacity. We've also applied pointer-events: noneand user-select: noneto preventing hover and active states from triggering.

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

White variant

Change the default .btn-closeto be white with the .btn-close-whiteclass. This class uses the filterproperty to invert the background-image.

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