Develop a custom 404 error page with animations to makeit more engaging.

Hey, I am Ajink, and today in this blog, we’re going to develop a custom 404 error page with engaging animations using HTML, CSS, and JavaScript. A custom 404 page not only informs users that they’ve reached a non-existent page but also provides a visually appealing and engaging experience.

HTML Code: create index.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link rel="stylesheet" href="style.css">
  <title>404 Error - Page Not Found</title>
</head>
<body>
  <div class="error-container">
    <div class="error-content">
      <div class="error-message">
        <h1>404</h1>
        <p>Oops! Page not found.</p>
      </div>
      <div class="animated-bg"></div>
    </div>
  </div>
  <script defer src="script.js"></script>
</body>
</html>

HTML Code Explanation:

  • We have a basic HTML structure with a container and content div containing an error message and an animated background.

CSS Code:

body {
  margin: 0;
  font-family: 'Arial', sans-serif;
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
  background-color: #3498db;
  overflow: hidden;
}

.error-container {
  text-align: center;
}

.error-content {
  position: relative;
}

.error-message {
  color: #fff;
  z-index: 2;
}

.error-message h1 {
  font-size: 8em;
  margin: 0;
}

.error-message p {
  font-size: 1.5em;
  margin: 10px 0 30px;
}

.animated-bg {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: linear-gradient(90deg, transparent, rgba(255, 255, 255, 0.2), transparent);
  animation: slide 3s linear infinite;
}

@keyframes slide {
  0% {
    transform: translateX(-100%);
  }
  100% {
    transform: translateX(100%);
  }
}

CSS Code Explanation:

  • The CSS provides styling for the custom 404 error page, including colors, fonts, and animations.
  • The .animated-bg class creates a sliding animation to give a dynamic effect.
