3. Link States
CSS provides four pseudo-classes to style hyperlinks in different states.
a:link{
color:blue;
}
a:visited{
color:purple;
}
a:hover{
color:red;
}
a:active{
color:green;
}

The text-decoration property is used to remove or add underlines to hyperlinks.

}

}
a:hover{
text-decoration:underline;
}
| Value | Description |

5. Styling Links as Buttons
CSS can make hyperlinks look like attractive buttons using background colors, padding, borders, and border-radius.
a{
background:#0d6efd;
color:white;
padding:10px 20px;
text-decoration:none;
border-radius:5px;

| background | Button background color |
| color | Text color |

The background-color property is used to change the background of hyperlinks. This is commonly used when creating button-style links.
a{
background-color:lightblue;
}
Example

background-color:#0d6efd;
color:white;
padding:10px 20px;
text-decoration:none;
}

color:white;
}
a:hover{
