a href shorthand pro tip: you can start a URL with two slashes ("//example.com") instead of having to type https:// every time, or a single slash ("/path/to.file") for the document root ("https://yoursite.neocities.org/path/to.file")
You can use dots for relative paths; If you are already in "yoursite.neocities/path/", gonna be like: "./to.file"; "./" means from this directory; if you are in "yoursite.neocities/path/example/": "../to.file", "../" means from the parent directory... And you can add more if you need to go "back" further "../../../../another.file".
Also related with links: using "referrerpolicy='no-referrer'" in your tag helps a little our privacy, since the browser don't send where are you comming from when clicking a link to external websites.
