HTML and CSS question

Question

Inside of HTML there is the <a href=""> tag which makes a link to another page. My question is what is the use for the pseudo class (a:link). If you can answer that would be greatly appreciated thank you.

Answer 1

When you click a link it changes color which means that you have visited the site.

With pseudo :link it only changes the style of unvisited links.
The opposite is :visited
