Question about <a href>

Question

What would be the difference between <a href> and <a href='#'>?

Answer 1

I mean both are hyperlinking, I get that, but is the '#' used to ref something inside the same html folder and regular href is mainly for external sources?

Answer 2

Use the href attribute to specify the url of the target of the link and # this means to locate the files,photos, videos,folder and make it a hyperlink

Answer 3

yes, # is used to target id, so if you href # it means self, it will reference the element containing the href, used for demo hyperlinks and for not allowing a page in a static website to call itself.

Answer 4

href="#" -> calling an item(tag) with particular id inside the same .html file
href="url" -> calling some external .html file or completely different external source (ex. Google.com)
