A generic close button for dismissing content like modals and alerts.
											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 close buttons change their
											opacity
											. We’ve also applied
											pointer-events: none
											and
											user-select: none
											to preventing hover and active states from triggering.
										
<button type="button" class="btn-close" disabled aria-label="Close"></button>
											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
											.
										
<button type="button" class="btn-close btn-close-white" aria-label="Close"></button>
