Play Html5 Video When Scrolled To

Have you ever wanted to spice up your webpage by adding some interactive features? Well, look no further! In this article, we're going to dive into the world of HTML5 and learn how to play a video automatically when it comes into view as you scroll on the webpage.

To achieve this cool effect, we will be using some simple JavaScript along with the HTML5 video element. Let's get started!

First things first, make sure you have a video that you want to play on your webpage. You can host the video on your server or use a public URL. Next, let's create the HTML structure for our video element:

<video id="video" controls>
  
  Your browser does not support the video tag.
</video>

In this code snippet, we have an HTML5 `video` element with the `controls` attribute that allows the user to play, pause, and adjust the video playback. The `source` tag inside the `video` element specifies the video file (`your-video.mp4`) and its type.

Now, let's dive into the JavaScript part. We will use the `Intersection Observer` API to detect when the video element comes into view as the user scrolls down the webpage. Here's the JavaScript code:

const options = {
  root: null,
  rootMargin: '0px',
  threshold: 0.5 // When 50% of the video element is visible
};

const observer = new IntersectionObserver((entries) => {
  entries.forEach((entry) => {
    if (entry.isIntersecting) {
      document.getElementById('video').play();
    } else {
      document.getElementById('video').pause();
    }
  });
}, options);

observer.observe(document.getElementById('video'));

In this JavaScript code snippet, we set up an `Intersection Observer` with some options. The `threshold` option specifies when the video should start playing, in this case, when 50% of the video element is visible in the viewport. Adjust the threshold value based on your design preferences.

We then check if the video element is intersecting with the viewport using `entry.isIntersecting`. If it is, we play the video using `document.getElementById('video').play()`, and if it is not, we pause the video using `document.getElementById('video').pause()`.

That's it! You have successfully implemented a feature that plays an HTML5 video when it scrolls into view on your webpage. Feel free to customize the video element, styling, and playback options to suit your needs.

In conclusion, adding interactive elements like autoplaying videos based on user scroll can enhance the user experience of your webpage. With a bit of HTML, CSS, and JavaScript magic, you can create engaging and dynamic content that captures the attention of your site visitors. Happy coding!
