How do you make a 404 page?

Question

I thought of making a 404 Page. but it seems hard.. how do i do it?

Here's what I did:

1. Made .htaccess File
2. Put: ErrorDocument 404 /page-not-found.html inside of the .htaccess file..
3. Added css design

Why doesn't it work?

I use glitch as my coding website. Is that the problem? Is there an alternative way to do this.?

Answer 1

If you want a custom 404 page for an app on Glitch, you'll need to be building a Node/full-stack app and configuring the page in your server-side code.

For example, I've got this simple Express app that sends any non-index route request to a 404 page: https://glitch.com/edit/#!/tranquil-hurricane-friction?path=server.js%3A25%3A0
