How to assign data-close attribute to closeBtn?
Steven Parker216,863 Points
In the quiz example, the attribute itself is not being assigned, but it is being used as a selector to assign a reference to the button element.
You can create an attribute selector by putting the attribute name in brackets (so in this case, "[data-close]").. This works in both CSS rules and for the querySelector method.
