Create a modern 404 Page Using HTML and CSS

Creating a simple 404 page using HTML and CSS is a straightforward process. A 404 page is displayed when a user tries to access a page on your website that doesn't exist. It's essential to create a user-friendly and informative 404 page to help your visitors navigate your website effectively. Here's a step-by-step tutorial on how to create a basic 404 page:

Step 1: Set up your project
Create a new folder for your project and create two files inside it: 404.html and style.css.

Step 2: Create the HTML structure (404.html)

<!DOCTYPE html>
<html lang="en">
        <meta charset="UTF-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0" />
        <link rel="stylesheet" href="style.css" />
        <title>404 - Page Not Found</title>
        <div class="container">
            <p>Page Not Found</p>
            <p>Sorry, the page you are looking for does not exist.</p>
            <a href="/">Go back to the home page</a>
        <div class="footer">
            <p>Explore more:</p>
            <div class="links">
                <a href="#">Link 1</a>
                <a href="#">Link 2</a>
                <a href="#">Link 3</a>

In this HTML structure, we've included a basic heading, a message informing the user that the page was not found, and a link back to the home page. You can customize this content as needed.

/* Reset some default styles to ensure consistency across browsers */
a {
    margin: 0;
    padding: 0;

/* Set the background color and font for the entire page */
body {
    background-color: #f5f5f5;
    font-family: Arial, sans-serif;
    text-align: center;

/* Style the container for the 404 content */
.container {
    background-color: #fff;
    border-radius: 5px;
    box-shadow: 0 0 10px rgba(0, 0, 0, 0.2);
    margin: 100px auto;
    max-width: 400px;
    padding: 20px;

/* Style the 404 heading */
h1 {
    color: #e74c3c;
    font-size: 100px;

/* Style the paragraph text */
p {
    font-size: 18px;
    margin: 20px 0;

/* Style the link to the home page */
a {
    color: #3498db;
    text-decoration: none;
    font-weight: bold;

/* Style the footer */
.footer {
    background-color: #2c3e50;
    color: #ecf0f1;
    padding: 20px 0;

/* Style the "Explore more" text in the footer */
.footer p {
    font-size: 18px;

/* Style the links with images */
.links {
    display: flex;
    justify-content: center;
    margin-top: 10px;

.links a {
    display: block;
    margin: 0 20px;
    text-decoration: none;
    color: #ecf0f1;
    transition: color 0.3s;

.links a:hover {
    color: #3498db;

In this CSS, we've styled the 404 page with a container for the content, centered it on the page, and added some basic styles for the heading, text, and link.

Step 4: Testing

Open the 404.html file in a web browser to test your 404 page. You can also link to it from your website by configuring your web server to serve the 404.html page when a 404 error occurs.

That's it! You've created a simple and visually appealing 404 page using HTML and CSS. You can further customize the design and content to match your website's branding and style.
