View Transitions Gallery Demo - Online Morphing Image Grid

The View Transitions API is a modern browser API that enables smooth animated transitions between different DOM states. It captures snapshots of elements before and after a change, then automatically morphs between them — handling position, size, and opacity. It's available in Chrome 111+ and other Chromium-based browsers, with growing cross-browser support.

Each image card is assigned a unique view-transition-name CSS property. When you switch layouts or filter images, we call document.startViewTransition(). The browser automatically captures the old positions and sizes, applies the DOM changes, then smoothly animates each card from its old location to its new one. The result is a seamless morphing effect with zero manual animation code.

As of 2025, the View Transitions API is supported in Chrome 111+, Edge 111+, Opera 97+, and Samsung Internet 22+. Safari and Firefox are actively working on implementation. This demo includes automatic fallback detection — if your browser doesn't support it, layout changes happen instantly without animation.

Absolutely! It's production-ready for Chromium browsers with graceful fallback. The basic pattern is simple: assign view-transition-name to elements you want to animate, then wrap DOM changes in document.startViewTransition(() => { /* update DOM */ }). For cross-browser compatibility, always feature-detect with if ('startViewTransition' in document) and provide a fallback.

The View Transitions API is hardware-accelerated and very performant. The browser uses compositor-level animations, meaning transitions run on the GPU without blocking the main thread. For best results, keep the number of named elements reasonable (under ~50) and avoid extremely large images during transitions. The API handles the heavy lifting efficiently.

You can customize animations using CSS pseudo-elements like ::view-transition-old() and ::view-transition-new(). Adjust animation-duration, animation-timing-function, or even replace the default cross-fade with custom keyframes. For finer control, target specific elements using ::view-transition-old(my-name) where "my-name" matches the element's view-transition-name.
