The a element in HTML represents a hyperlink, and it is used to link one page to another. In CSS, you can use the a selector to style the appearance of hyperlinks.

Here is an example of how to use the a selector to style the appearance of hyperlinks:

a {
color: blue;
text-decoration: none;
}

a:hover {
color: red;
}

a:visited {
color: purple;
}

In this example, the a selector sets the color of hyperlinks to blue and removes the text decoration. The a:hover selector changes the color of the hyperlink to red when the mouse cursor is over the hyperlink. The a:visited selector changes the color of the hyperlink to purple after the hyperlink has been visited.

You can also use the a selector to style the appearance of hyperlinks in different states, such as a:active, a:focus, and a:target.


a:active {
color: green;
}

a:focus {
outline: 2px solid orange;
}

a:target {
background-color: yellow;
}

In this example, the a:active selector changes the color of the hyperlink to green when the hyperlink is being clicked, the a:focus selector adds an orange outline around the hyperlink when it has focus, and the a:target selector changes the background color of the hyperlink to yellow when it is the target of the current page.
