CSS Pseudo-classes
A CSS pseudo-class is a keyword that can be added to a selector, to define a style for a special state of an element.
Some common use for pseudo-classes:
- Style an element when a user moves the mouse over it
- Style visited and unvisited links differently
- Style an element when it gets focus
- Style valid/invalid/required/optional form elements
- Style an element that is the first child of its parent
Syntax
Pseudo-classes are always denoted by a single colon (:) followed by the pseudo-class name:
selector:pseudo-class-name {
