Learn How to Create a Full-Screen Video Background with CSS

The following solution provides a full-screen video background using HTML, CSS, and JavaScript. I’ve optimized the HTML, CSS, and JS into separate files and added SEO-friendly meta tags.

HTML Code (`index.html`):

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta name="description" content="Learn how to create a stunning full-screen video background with CSS. This tutorial includes HTML, CSS, and JavaScript to control a background video element that plays automatically and can be paused or resumed.">
    <meta name="keywords" content="full-screen video background, CSS video background, autoplay video, background video with controls, HTML5 video background, web design, interactive video background">
    <meta name="author" content="Your Name">
    <meta property="og:title" content="Learn How to Create a Full-Screen Video Background with CSS">
    <meta property="og:description" content="Create a full-screen video background with autoplay and pause functionality using HTML, CSS, and JavaScript. Enhance your website's design with a dynamic video backdrop.">

    <link rel="stylesheet" href="style.css">
</head>
<body>

<video autoplay muted loop id="myVideo">
  <source src="rain.mp4" type="video/mp4">
  Your browser does not support HTML5 video.
</video>

<div class="content">
  <h1>Heading</h1>
  <p>Lorem ipsum dolor sit amet, an his etiam torquatos. Tollit soleat phaedrum te duo, eum cu recteque expetendis neglegentur. Cu mentitum maiestatis persequeris pro, pri ponderum tractatos ei. Id qui nemore latine molestiae, ad mutat oblique delicatissimi pro.</p>
  <button id="myBtn" onclick="myFunction()">Pause</button>
</div>

<script src="script.js"></script>

</body>
</html>

CSS Code (`style.css`):

/* Reset default margin and padding */
* {
  box-sizing: border-box;
}

body {
  margin: 0;
  font-family: Arial, sans-serif;
  font-size: 17px;
}

#myVideo {
  position: fixed;
  right: 0;
  bottom: 0;
  min-width: 100%; 
  min-height: 100%;
  object-fit: cover; /* Ensure video covers entire viewport */
}

.content {
  position: fixed;
  bottom: 0;
  background: rgba(0, 0, 0, 0.5); /* Transparent black overlay for readability */
  color: #f1f1f1;
  width: 100%;
  padding: 20px;
}

#myBtn {
  width: 200px;
  font-size: 18px;
  padding: 10px;
  border: none;
  background: #000;
  color: #fff;
  cursor: pointer;
}

#myBtn:hover {
  background: #ddd;
  color: black;
}

JavaScript Code (`script.js`):

// Access video element and button
var video = document.getElementById("myVideo");
var btn = document.getElementById("myBtn");

// Function to toggle video play/pause
function myFunction() {
  if (video.paused) {
    video.play();
    btn.innerHTML = "Pause"; // Change button text to "Pause" when video is playing
  } else {
    video.pause();
    btn.innerHTML = "Play"; // Change button text to "Play" when video is paused
  }
}

Explanation:

HTML:
- A <video> tag is used for the background video. The autoplay, muted, and loop attributes ensure that the video plays automatically without sound and loops indefinitely.
- The <div class="content"> contains a heading, paragraph, and a button to control the video (play/pause).
CSS:
- The video is positioned with position: fixed and stretched to cover the entire viewport using min-width: 100% and min-height: 100%. The object-fit: cover ensures that the video covers the whole screen without distortion.
- The .content class adds a semi-transparent black background to the text for better readability on top of the video.
- The button is styled to be easily clickable and changes appearance on hover.
JavaScript:
- The JavaScript code is responsible for toggling the video between playing and paused states. The button text changes based on the current state of the video (play or pause).

Conclusion:

With this solution, you can create a full-screen video background that adds a dynamic, engaging effect to your website. The tutorial includes HTML, CSS, and JavaScript for controlling the video playback.
