Ans. It is a CSS technique that sets the style when an element changes its state. E.g. style changes when mouse hover, different styles for visited or unvisited links, etc. There are four different types of pseudo-classes: Links: These pseudo-classes are used to style the link both in its normal state by default and when it has already been visited Dynamic: Dynamic pseudo-classes can be applied to any element to define how they are shown when the cursor is located on them, or by clicking on them or when they are selected Structural: Structural pseudo-classes allow to style elements based on an exact numerical position of the element Others: Some elements can be styled differently based on the language or what type of label they are not.
