Definition:
It is a link that takes users from one website to another, just like going from one house to another in real life.
Developers use external links to open webpages from other websites.
When a webpage opens another webpage from a different website, it is called an External Link.
Syntax:
<a href="https://www.google.com">Visit Google</a>
Example:
<a href="https://www.youtube.com">Open YouTube</a>
