The most common use case:
.avoid-clicks {
pointer-events: none;
}
Through CSS, you can make clicks not register events on elements that match that selector. Useful for something like disabling current page navigation.
There are many other possible values though. auto is the reset for it and it can inherit. The rest of them are for SVG.
pointer-events: auto | none | visiblePainted | visibleFill | visibleStroke | visible | painted | fill | stroke | all | inherit;
