An absolute URL includes the scheme and host:

<a href="https://example.com/about/">About Example</a>

Use an absolute URL when you link to another website.

For pages on the same site, you can use a relative URL. A path that starts with / begins at the root of the current site:

<a href="/about/">About us</a>

This points to /about/ no matter which page contains the link.

A path without the first slash is relative to the current document:

<a href="photos/">Photos</a>

If the current page is https://example.com/trips/copenhagen/, that link goes to:

https://example.com/trips/copenhagen/photos/

Use ../ to move up one directory:

<a href="../">All trips</a>

Relative URLs are useful because they keep working when the whole site moves to another domain. The tradeoff is that you need to understand which document they are relative to.
