CSS Pseudo-classes

What are Pseudo-classes?

A pseudo-class specifies a special state of an element.

For example, it can be used to:

  • Style an element when a user mouses over it.
  • Style visited and unvisited links differently.
  • Style an element when it gets focused.

Syntax

The syntax of pseudo-classes:

selector:pseudo-class {

  property: value;

}

Anchor Pseudo-classes

Links can be showed in different ways

HTML
				
					<h2>Styling a link depending on state</h2>

  color: green;
}

/* mouse over link */
a:hover {
  color: hotpink;
}

/* selected link */
a:active {
  color: blue;
}

				
			

Output
