```
a.navigation:link {color: white; text-decoration: none;
    padding: 20px 20px 20px 20px;
    border: 0.5px solid white;
    border-radius: 70px 70px;}  

a.navigation:visited {color: lightgreen;
    padding: 20px 20px 0px 20px;
    border: 0.5px solid lightgreen;
    border-radius: 70px 70px 0px 0px;}

```

The css above is what I'm using for the unvisited page and visited page. I want a visited page that has been left to revert to unvisited css style.
