Why we used #

Answer 1

Did you mean use # in href attribute? For example <a href="#">Link</a> ?
It is used to prevent browser refresh or move to another page when you click the link.

But if you use :
<a href="other_page.html#content">Link</a>

When you click the link, the page will be directed to other_page.html and scroll down to the tag that contains attribute id="content", for example :

<div id="content">Content</div>
