Custom 404 Error Page Design using HTML & CSS

Hello readers, Today in this blog you’ll learn how to create a Custom 404 Error Page using only HTML & CSS. Earlier I have shared many blogs related to Web Design like (Responsive Footer Design, Responsive Drop-down Menu, and Responsive Sidebar Menu). But now I’m going to create a 404 Error page which is also a part or section of the Website.

The HTTP 404, 404 Not Found, or 404 Page Not Found error message is a Hypertext Transfer Protocol (HTTP) standard response code, in computer network communications, to indicate that the browser was able to interact with a given server but the server could not locate what was requested. This error displays when the user-requested page or URL doesn’t exist on a particular site.

In this program (Custom 404 Error Page Design), at first, on the webpage, there is a linear-gradient background with a white container box. Inside the box, there is title text, description, and two buttons. That 404 text has a mask animation that means there is gradient-color animation that flows top to bottom. This error page is created only for design purposes and it won’t redirect you to any other page when you click on the buttons.

If you’re feeling difficult to understand what I am saying. You can watch a full video tutorial on this program (Custom 404 Error Page Design).
