What is href=“#” and why is it used?

Question

On many websites I see links that have href=\"#\". What does it mean? What is it used for?

Answer 1

It's a link that links to nowhere essentially (it just adds "#" onto the URL). It's used for a number of different reasons. For instance, if you're using some sort of JavaScript/jQuery and don't want the actual HTML to link anywhere.

It's also used for page anchors, which is used to redirect to a different part of the page.
