Lazy Loading
A technique that defers loading of off-screen images and iframes until they are near the user's viewport.
Lazy loading reduces the initial page payload by not loading images that are below the fold until users scroll toward them. The native loading='lazy' attribute enables browser-level lazy loading without JavaScript. Important: the LCP element should never be lazy-loaded — lazy loading the hero image is a common mistake that directly worsens LCP scores.
