hover is not a pseudo element, but a pseudo class. Pseudo-classes are used to select a specific state or behavior of an element, while pseudo-elements are used to add styles to specific parts of an element. Because :hover is used to select a specific state of an element rather than adding styles to a specific part of the element, you can use the :hover pseudo-class to style the mouseover state of an element, and you can use the :hover pseudo-class to add hover effects to links. The link's color, background color, etc. can change when the mouse hovers over it.

hover is a pseudo-class in CSS, not a pseudo-element.

In CSS, pseudo-classes and pseudo-elements are two different concepts. Pseudo-classes are used to select a specific state or behavior of an element, while pseudo-elements are used to add styles to specific parts of an element.

Pseudo-classes are used to select elements based on their status or behavior. For example: the hover pseudo-class is used to select the status when the mouse is hovering over the element. Other common pseudo-classes include :active (the state when the selected element is activated), :focus (the state when the selected element receives focus), etc.

The pseudo-element is used to add styles to specific parts of the element. Pseudo elements are represented by using a double colon (::) in the selector. Common pseudo-elements include ::before (add content before element content), ::after (add content after element content), etc.

So, hover is called a pseudo-class, not a pseudo-element. Because :hover is used to select a specific state of an element, not to add styles to a specific part of the element.

Use the :hover pseudo-class to add styles to the mouse hover state of elements. For example, you can add a hover effect to a link through the :hover pseudo-class. When the mouse hovers over the link, the link's color, background color, etc. can change.

Here is a sample code that demonstrates how to use the :hover pseudo-class to add a hover effect to a link:

a {
  color: blue;
  text-decoration: none;
}
a:hover {
  color: red;
  background-color: yellow;
}
Copy after login

In the above code, when the mouse hovers over the link, the link The color will change to red and the background color will change to yellow.

In summary, hover is a pseudo-class in CSS, used to select the mouse hover state of elements. Pseudo-classes are used to select the state or behavior of an element, unlike pseudo-elements, which are used to add styles to specific parts of an element.
