Animation
Animation is a planned visual change over time. It can have several steps, states, or repeats.
@keyframes / WAAPI / GSAPA real example
A success check mark draws itself, settles, then lets the next action take attention.
Main parts
- 01Trigger
- 02Property change
- 03Timing model
- 04Reduced-motion result
Use it when
Use animation when movement explains a change, cause, progress, or part of the brand’s character.
Do not use it when
Never add motion with no message or let an animation loop without control.

@keyframes / WAAPI / GSAP Before you ship
Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience.
Outcome: Use or define Animation to make the visual experience clear and easy to use. User context: A success check mark draws itself, settles, then lets the next action take attention. Design concept to apply: Animation. Why it fits: Use animation when movement explains a change, cause, progress, or part of the brand’s character. Do not use it when: Never add motion with no message or let an animation loop without control. Design requirements: Set the content order, shared design values, and reusable components. Define how the layout changes by screen size and state. Keep useful design choices separate from decoration. Inclusion and resilience: Check contrast, zoom, languages, themes, and reduced motion when needed. Do not use color or effects as the only way to show meaning. Acceptance criteria: The design stays clear on phones and desktops, at zoom, in every theme, and in all supported languages. Interactive states stay clear and consistent. Evidence and limits (evidence boundary): A formal document may still be a draft, release candidate, or final version. Check its status and browser or platform support. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.
