How can we create a custom error 404 page using HTML CSS & JS? Solution: Check out this custom Error 404 Page With Counting Numbers Using CSS Bootstrap.

Previously I have shared an Animated Error 404 Page Design With Particle JS, But this one is with counting numbers effect. Basically, 404 is error message for page not found in Hypertext Transfer Protocol standard response code. When anyone clicks on a broken link on the webpage, then the page appears.

Today you will learn to create a 404 page design with counting numbers effect. There is an animated counting numbers effect in the 404 code, and also a massage page not found in the downside. Also, there is a double-side slant section outside the zero of 404, that creates the design more attractive.

So, Today I am sharing Custom Error 404 Page With Counting Numbers Using CSS Bootstrap. This is a responsive design means it will fit on every screen size. And there is a counting number effect which is powered by pure JavaScript, there is not any library. I think this program or design will be very useful for your website or any other project.

If you are thinking now how this 404 page actually is, then see the preview given below.

Custom Error 404 Page With Counting Numbers Effect Source Code

Before sharing source code, let’s talk about it. First I have created 3 HTML span inside divs and put two class names. After that, I have put a page not found message in heading tag. Also, there are many more divs or sections for multiple purposes like shadow, outside circle, etc.

Using CSS I have done many works, like place elements on the right place, styling all content, etc. There I have created a slant section outside of the middle number which is zero, you can see in the preview at actual things what I am talking about. As you know this is also a responsive design, I have used CSS @keyframe property to creating it responsive.

Now using JavaScript I have created the counting numbers effect. For counting effect used JavaScript for loop
for() command (info). All other left things you will understand after getting the code, I can’t explain all in writing. For creating this you have to create 3 files. First for HTML, second of CSS and the third for JavaScript. Follow the steps to creating this without any error.

index.html
