## Hover Selector
The CSS `:hover` selector is one of many pseudo-classes that are used to style elements.
The :hover selector is used to select elements when you mouse over them.
The :hover selector can be used on all elements, not only on links.
Use the :link selector to style links to unvisited pages, the :visited selector to style links to visited pages, and the :active selector to style the active link.
Note: :hover MUST come after :link and :visited (if they are present) in the CSS definition, in order to be effective!
CSS Syntax
:hover {
css declarations;
}
The hover selector only applies the styles provided in the rule when the element enters the hover state.
That is when the user hovers over the element with their mouse.
```css
button {
color: white;
background-color: green;
}
button:hover {
background-color: white;
border: 2px solid green;
color: green;
}
```
In the example above, the button's normal styling is white text on a green button.
When a user hovers over the button with their mouse the rule with the `:hover` selector will become active and the button's style will change.
