Just looking at it from my basic perspective, it seems like should have a source instead of a href attribute, since it binds/sources a file much like does.
This was driving me insane! Didn’t realise the . was outside of the grey box… I’m sticking to copy and paste from now on!

Thats what has happened to me really confusing
I know you can link things other than websites. Is the anchor tag only for ‘linking’ things? Any other functions/features?
