Behavior comparison
Skeleton shimmer vs State transition
Decisive difference
Skeleton shimmer addresses optional loading decoration; State transition addresses persistent state feedback. They can be combined when both needs apply.

Motion & Effects
Try it
Does motion explain a change, report state, or only decorate?
Skeleton shimmer
Shared trial context
An item moves, changes state or waits for content. Which information must survive without motion?
Skeleton shimmer
Static preview: state and result remain readable without motion. Activate the demo to compare the parameter, pause and try the fallback.
Compare 1200 and 2400 ms per sweep. Speed changes the decoration, not the load. Show content completes this local simulation; no network request is made.
State transition
Static preview: state and result remain readable without motion. Activate the demo to compare the parameter, pause and try the fallback.
Compare an instant update with a 200 ms fade. Saved appears immediately in both cases; only the decorative check fades.
What this example shows
Skeleton reserves the content shape; shimmer is optional decoration on that shape. Unlike a progress bar, neither measures completion.
Which fits your need?
Skeleton shimmer
Demonstrate a loading placeholder with reserved space and persistent Loading text.
State transition
Confirm a completed local action with persistent text and an optional short fade.

Three criteria to choose
- Use case
Skeleton shimmer
Demonstrate a loading placeholder with reserved space and persistent Loading text.
State transition
Confirm a completed local action with persistent text and an optional short fade.
- Interactivity
Skeleton shimmer
Adjust one parameter for optional loading decoration; pause or use a static result.
State transition
Adjust one parameter for persistent state feedback; pause or use a static result.
- Mobile behavior
Skeleton shimmer
Native touch controls; system motion reduction always wins.
State transition
Native touch controls; system motion reduction always wins.

State transition
Explicit activation to demonstrate persistent state feedback.
- Modality
Skeleton shimmer
Non-modal; surrounding content stays usable.
State transition
Non-modal; surrounding content stays usable.
- Placement
Skeleton shimmer
Inside a bounded specimen; no page-level decoration.

- Interactivity

State transition
Adjust one parameter for persistent state feedback; pause or use a static result.
- Focus
Skeleton shimmer
Focus stays on the activated control. Reset restores focus to its button.
State transition
Focus stays on the activated control. Reset restores focus to its button.
- Dismissal
Skeleton shimmer
Pause freezes playback; static fallback cancels it. Leaving the specimen cancels its animation and removes listeners.
