🎥 How to Embed Responsive Videos in Shopify (or Any Site) – 2025 Update

Want to add YouTube or Vimeo videos to your Shopify store without breaking your site’s layout on mobile? This guide will show you the latest and cleanest way to embed fully responsive videos—no matter what device your customers are on.

âś… Why You Need Responsive Videos

A non-responsive video embed can break your layout, create ugly scroll bars, or worse—disrupt the user experience. Making your videos responsive ensures:

  • Smooth scaling on mobile and tablet
  • Cleaner layout and better UX
  • Faster load times with lazy loading
  • Higher engagement with media-rich pages

Let’s dive into the modern way to embed responsive videos.

🔧 Method 1: CSS aspect-ratio (Modern & Recommended)

Thanks to modern CSS support, we can ditch the padding-hack method and use the native aspect-ratio property for cleaner code.

HTML:

CSS:

.responsive-video {
aspect-ratio: 16 / 9;
width: 100%;
max-width: 100%;
}

.responsive-video iframe {
width: 100%;
height: 100%;
border: 0;
display: block;
}

🕵️‍♂️ Bonus: Use YouTube Privacy-Enhanced Mode

Want to improve user privacy and potentially boost performance? Use YouTube’s privacy-enhanced embed:

This prevents YouTube from tracking visitors unless they interact with the video.

🚀 Enable Lazy Loading (Native Browser Support)

No external scripts needed! Just add loading="lazy" to your

This tells modern browsers to delay loading the video until it’s in view—improving page speed and Core Web Vitals.

⚙️ Method 2: Fallback for Older Browsers

If you still need broader compatibility (or can’t use aspect-ratio), here’s the classic padding-bottom technique:

HTML:

CSS:

.video-wrapper {
position: relative;
padding-bottom: 56.25%; /* 16:9 ratio */
height: 0;
overflow: hidden;
}

.video-wrapper iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
border: 0;
}

🛍 Works Great for Shopify Stores

If you’re embedding a video on a Shopify product page, blog post, or custom section, you can drop the above code into the Custom HTML section or directly into your theme’s Liquid templates.
