About Lazy Load Iframe
What This Component Solves
Most iframe embeds load instantly, even if the visitor never scrolls to them. That can trigger heavy third-party scripts too early, increase network work, and hurt speed metrics.
Lazy IFrame delays the embed until it is actually needed, so your above-the-fold experience stays lightweight and responsive.
Core Features
Loads the iframe only when it enters view using IntersectionObserver
Loads once per URL to avoid duplicate work
Uses requestIdleCallback when available to mount during idle time
Holds layout space to avoid layout shift while loading
Works responsively inside Framer layouts
No external dependencies
Loading Experience
Instead of a blank box, Lazy IFrame can show a minimal glass-style loader that looks like a lightweight dashboard placeholder. This makes the loading state feel intentional and premium, without distracting motion.
Structured UI skeleton placeholder
Subtle shimmer animation
Customizable surface, accent, and shimmer speed
Keeps the page stable while the iframe initializes
