Shared Element Transition

A card grows into a full detail view, keeping one visible container that reshapes and reveals new content.

Add a "Container Transform" transition (also called card expand to detail or an expandable card) to [where].
When the card is opened, the same container should grow smoothly into the full detail view, its old content fading out quickly and the new content fading in once it has nearly finished growing; closing plays it in reverse.
Keep it one continuous container rather than a crossfade between two separate boxes, and move focus into the detail view when it opens.

An element appears to move and resize into a matching element in a new spot, sharing one identity.

Add a "Shared Layout Animation" (also called an in-page shared element) to [where].
When the selection changes, the element should appear to move and resize smoothly from its old spot into its new one, easing gently into place, so it reads as one object rather than two.
Show only one copy at any moment, and keep the surrounding layout from jumping while it moves.

A thumbnail scales up from its place into a large centered view over a dimmed backdrop.

Add a "Lightbox Zoom" (also called an image zoom overlay or Medium-style zoom) to [where].
Clicking a thumbnail should make it grow smoothly from its own place into a large centered view while the page behind fades back, and closing should shrink it back into the same place.
Close it with Escape or a click on the backdrop, move focus into the view while it is open, and return focus to the thumbnail afterward.

Elements glide smoothly to their new positions and sizes after the layout changes.

Add a "FLIP Layout Animation" (also called a layout animation or First-Last-Invert-Play) to [where].
When the layout changes, each element should glide from its old position to its new one instead of jumping, quick at first and easing gently into place.
Animate with transforms only so the page doesn't reflow on every frame, and switch straight to the new layout for users who prefer reduced motion.

The new page slides in from one side while the old page slides out, with direction following navigation depth.

Add a "Slide Page Transition" (also called push / pop or a directional slide) to [where].
Going forward, the new page should push in from the side while the old page slides out the other way; going back, both should move in the opposite direction: smooth, easing in and out.
Tie the direction to navigation depth, including the browser's back button, and keep the page from scrolling sideways during the slide.

The old page scales up or down and fades while the new page scales into place.

Add a "Zoom Page Transition" (also called a scale transition or zoom in / out) to [where].
Drilling in, the old page should scale up slightly and fade out while the new page grows from slightly smaller into place; going back, it should zoom out the opposite way: smooth and quick.
Keep the scaling subtle so the content stays readable throughout, and use a plain fade for users who prefer reduced motion.

The new view is revealed inside a circle that expands from the click point.

Add a "Circular Reveal" transition (also called a clip-path circle expand or theme toggle reveal) to [where].
The new view should appear inside a circle that grows outward from the pressed control until it covers the whole area: smooth and steady, easing in and out.
Start the circle exactly where the control was pressed, and switch instantly without the circle for users who prefer reduced motion.
