What is a pseudo-class?

It’s a CSS method that changes the style of an element as its status changes. For example, style changes when the mouse hovers over, various styles for visited and unvisited links, and so on.

Pseudo-classes are divided into four categories:

  1. Links: These pseudo-classes are used to style links both in their default state and after they have been viewed.

  2. Dynamic pseudo-classes can be applied to any element to control how it appears when the cursor is over it, when it is clicked on, or when it is selected.

  3. Structural pseudo-classes enable the styling of components based on their exact numerical location.

  4. Others: Depending on the language or the kind of label, some components might be stylized differently.
