How to Add a Video Background in WordPress Using HTML?

Adding a video background to your WordPress website can dramatically enhance visual appeal and user engagement. When used thoughtfully, video backgrounds help tell a brand’s story, create ambiance, and capture attention without relying on stock images or graphics. Whether you’re running a portfolio site, promoting an event, or enhancing a homepage banner, a video background offers a modern, immersive experience.

But how do you actually implement one using HTML in WordPress – especially when most page builders don’t offer fine-tuned code control?

This article explains exactly how to add a video background in WordPress using HTML. We’ll walk through use cases, placement methods, embedding techniques, common mistakes, and mobile considerations – all with clear, practical guidance. Whether you use the default Block Editor or a theme with custom HTML support, this guide covers your options.

Why Use a Video Background?

Visual Appeal Without Heavy Graphics

Instead of static banners or slideshows, a muted video loop can instantly establish a tone – whether that’s serene nature footage for a spa or energetic street shots for a fashion brand.

Context and Storytelling

A background video subtly reinforces what your page is about without overwhelming text or requiring interaction.

Conversion and Engagement

When used sparingly, video backgrounds may reduce bounce rates and keep users engaged longer – especially on landing pages and hero sections.

What You Need Before You Begin

Before embedding a video background, make sure you have:

  • A lightweight, looping video file (MP4, ideally under 5 MB)
  • Fallback image for mobile devices
  • Access to your WordPress theme files or a Custom HTML block
  • Autoplay permission (videos should be muted for autoplay to work on most browsers)

💡 Tip: Host the video file locally or on a fast CDN. Avoid platforms like YouTube or Vimeo for background use – they don’t support autoplay backgrounds reliably.

Method 1: Adding Video Background with Custom HTML in a Page

If you’re using the Block Editor or Elementor/Divi, you can still embed HTML code using a Custom HTML block or code widget.

Step-by-Step:

  1. Upload Your Video
    • Go to your WordPress dashboard → Media → Add New
    • Upload your MP4 file (keep the size small for performance)
    • Copy the URL of the uploaded video
  2. Use a Custom HTML Block
    • Open the page where you want the video
    • Add a Custom HTML block
  3. Paste the HTML Code

<div style=”position: relative; overflow: hidden; height: 100vh;”>

  <video autoplay muted loop playsinline 

         style=”position: absolute; top: 0; left: 0; min-width: 100%; min-height: 100%; object-fit: cover; z-index: -1;”>

    <source src=”https://yourdomain.com/wp-content/uploads/2025/07/video.mp4″ type=”video/mp4″>

    Your browser does not support the video tag.

  </video>

  <div style=”position: relative; z-index: 1; text-align: center; padding-top: 40vh;”>

    <h1 style=”color: white;”>Welcome to Our Site</h1>

    <p style=”color: white;”>Your story starts here.</p>

  </div>

</div>

4. Preview and Adjust

  • Replace the text and styling as needed
  • Make sure it works across devices (desktop/tablet/mobile)

Method 2: Adding Video Background to Header or Hero Section via Theme Files

For developers or users comfortable with theme editing, embedding a video in your theme’s header.php or custom section is more seamless.

Steps:

  1. Access WordPress Theme Editor
    • Go to Appearance → Theme File Editor
    • Open header.php or a relevant section file
  2. Insert the Code Block

Insert the same video HTML snippet inside a relevant container:

<?php if ( is_front_page() ) : ?>

  <div class=”video-banner”>

    <video autoplay muted loop playsinline>

      <source src=”<?php echo get_template_directory_uri(); ?>/assets/video/hero.mp4″ type=”video/mp4″>

    </video>

    <div class=”video-overlay-content”>

      <h1>Your Brand Story</h1>

      <p>Start strong with a bold introduction.</p>

    </div>

  </div>

<?php endif; ?>

  1. Add CSS Styling

.video-banner {

  position: relative;

  height: 100vh;

  overflow: hidden;

}

.video-banner video {

  position: absolute;

  top: 0; left: 0;

  min-width: 100%;

  min-height: 100%;

  object-fit: cover;

  z-index: -1;

}

.video-overlay-content {

  position: relative;

  z-index: 1;

  color: white;

  text-align: center;

  padding-top: 40vh;

}

Method 3: Use a Plugin with HTML Embed Support

If you prefer not to edit code, plugins like Elementor, WPBakery, or Kadence Blocks allow you to insert HTML or shortcodes.

Plugin-Compatible Method:

  1. Use the same <video> embed code
  2. Paste it into a Raw HTML block, code widget, or shortcode box
  3. Style it using inline CSS or custom CSS settings in the page builder

Note: Always check mobile responsiveness in your page builder preview.

Considerations for Mobile Devices

Not all mobile browsers support autoplay video backgrounds. Here’s how to manage that:

Best Practices:

  • Use playsinline, muted, and autoplay together in your <video> tag
  • Provide a fallback image using CSS background-image
  • Use media queries to hide the video and show a static background on smaller screens

Sample CSS for Fallback:

@media (max-width: 768px) {

  .video-banner video {

    display: none;

  }

  .video-banner {

    background: url(‘fallback.jpg’) center center / cover no-repeat;

  }

}

Performance and SEO Impact

What to Watch:

  • Large files can slow down page load
  • Background videos don’t have audio or captions, so they don’t add direct SEO value
  • Use lazy loading, compress your video, and test your Core Web Vitals

Pro Tips:

  • Convert your video to multiple formats if needed (.webm, .mp4)
  • Host on a CDN for faster global delivery
  • Keep video lengths short (under 15 seconds)

Common Mistakes to Avoid

Conclusion

Adding a video background in WordPress using HTML doesn’t require advanced coding skills – it just needs the right approach and testing. Whether you’re enhancing your homepage hero section, a landing page, or a banner, the HTML <video> method gives you full control over styling, behavior, and fallback options.

Just remember: use video to enhance your content, not distract from it. Keep it lightweight, test it thoroughly, and always consider mobile users in your design decisions.

FAQs

What is the HTML code to add a video background in WordPress?

Use the <video> tag with autoplay, muted, loop, and playsinline attributes. Style it using CSS to cover the section fully.

Can I use YouTube videos for background in WordPress?

No, YouTube videos do not reliably autoplay as backgrounds. Use MP4 files hosted locally or via a CDN.

How do I add a fallback image for mobile?

Use CSS media queries to hide the video on small screens and show a background image instead.

Does a video background affect website speed?

Yes. Large video files can slow loading. Always compress your video and limit its length for optimal performance.

Can I add a video background without a plugin?

Yes. You can use a Custom HTML block or edit theme files directly with HTML and CSS.

Why isn’t my video background autoplaying?

Most browsers require muted videos for autoplay to work. Ensure you include muted and playsinline attributes.

Should I use WebM or MP4 for background videos?

MP4 is widely supported and ideal for most use cases. WebM can be added as a secondary source for better browser coverage.

What size should my background video be?

Keep it under 5 MB if possible. Use 720p resolution or less, and trim unnecessary frames to reduce load time.
