What is a “404 Error”?

The standard HTTP response code indicates that the client can communicate with the server. Still, the server cannot find the data as requested. Furthermore, the requested resource may be available in the future, which does not guarantee the existence of the previous content.

What causes a 404 error?

1. The page address was mistyped in the address bar, or the user followed a “broken” link.

2. The requested page has never been on the site.

3. The page at the specified address used to exist but was moved, renamed, or deleted.

The design of the 404 Page depends on the overall idea of ​​the site. If the site is funny and with jokes, then the 404 will be funny. If the site is more serious and businesslike, 404 will be more conservative.

By creating pleasant 404 pages, we strive to remove the negative from the user because he did not find what he was looking for.
