Href is short for “Hypertext Reference” and is an HTML attribute. The href attribute is mainly used for
<a> tags to specify the URL for a webpage the link leads to (whether it be on a different section of the same page, or on a completely different webpage).
How to use
<a href="https://www.freecodecamp.org">This is an absolute URL</a> <a href="index.html">This is a relative URL</a>
<a href="#top">Go to top</a>
It will take you to that position in the page where
id="top" is given.
