Chi tiết kỹ thuật
Reels was created by Facebook (now Meta) and is now supported by most social platforms. The four required properties are og:title, og:type, og:image, and og:url. Images should be at least 1200x630 pixels for high-resolution displays; images below 600x315 appear as small thumbnails. og:image must be an absolute URL — relative paths are not supported. Facebook caches previews aggressively; use their Sharing Debugger to clear the cache and preview changes.

```html <!-- Reels: social markup example --> <meta property="og:title" content="Page Title"> <meta property="og:description" content="Description for social sharing."> <meta property="og:image" content="https://example.com/image.png"> ```
