25 creative 404-Error Pages with cool animations

If you call up a page that does not (no longer) exist, you are redirected to 404 pages. But that’s not bad, because 404 pages can work wonders with a little creativity, so that visitors don’t leave your site.
404 pages are called this way, because in case a page does not or no longer exist, the server returns the status code 404 to show that the requested page does not (no longer) exist.
The pens can be used as a template template or as examples for your own site, let yourself be inspired! And let’s be honest…404 jokes are the best! ?
