element, and the poster image is used as the placeholder before playback starts. This step connects the settings defined in the schema with the actual video that appears to customers.
Add Styling (Optional) The video element will render without any styling, but it may not adapt well to different screen sizes. Adding CSS ensures that the video scales correctly and fits within the layout of the theme. A simple rule to make the video width responsive can be added in the theme’s stylesheet or inline in the section file. This ensures that the video looks consistent across devices such as desktops, tablets, and phones. .shopify-video-section video {
width: 100%;
height: auto;
display: block;
}
Enable Section in Theme Editor After the section file has been created and markup added, the section becomes available in the Shopify Theme Editor. From the admin panel, when you go to Online Store → Themes → Customize , the new video section will appear as an option to add to supported templates. Merchants can then insert the section, enter the video URL, upload a poster image, and configure playback options. Optimizing Video Playback Videos can vary in size and format, so it is important to handle them properly. Short videos can be uploaded directly and served from Shopify’s CDN. Larger files are better hosted externally on services like AWS S3, Cloudflare, Vimeo, or YouTube, and then embedded via URL. Using a poster image prevents a blank screen from appearing before playback. Autoplay should be muted to comply with browser policies. These ensure that the video loads efficiently and behaves consistently across different browsers.
