Selectors decide which elements that USS rules affect.
USS supports a set of simple selectors that are analogous, but not identical, to simple selectors in CSS. A simple selector matches elements by element type, USS class, element name, and wildcard.
You can combine simple selectors into complex selectors, or append pseudo-classes to them to target elements in specific states. USS supports descendant, child, and multiple complex selectors.
