Smart Animate & Component States
Smart Animate interpolates property changes between two connected frames automatically, creating smooth UI animations without code. Combined with Figma's Component States, it enables realistic micro-interactions - toggle switches, expanding menus, button feedback - that make prototypes feel indistinguishable from real apps.
How Smart Animate Works
Smart Animate matches layers with identical names between two connected frames and animates any property changes: position, size, opacity, fill color, corner radius, rotation. Requirements: layer names must be identical (case-sensitive) in both frames. The connection must use 'Smart Animate' as the transition type. Best easing for UI: Ease In Out at 300ms. For spring-like feel: Spring Curve at 500ms. Practical use: animate a bottom sheet sliding up by placing the sheet frame in Frame A (below viewport) and Frame B (partially visible). Smart Animate moves it smoothly between positions.

Component States - Interactive Hover & Press
- Component States let a single component handle Default → Hover → Pressed → Disabled transitions without connecting separate full-page frames
- Creating: Select master component → right-click → 'Add component state'. Design the Hover variant. In Prototype mode, set 'On hover → State=Hover', 'On mouse leave → State=Default'
- Real-world use: A button with 5 states (Default, Hover, Pressed, Loading, Disabled) handles all interactions automatically in prototype mode - no 5-frame setup needed
- Toggle switch example: Create OFF and ON variants → connect 'On Click → State=ON' and 'On Click → State=Default' with Smart Animate → the toggle slides and changes color automatically in preview
- Common mistake: duplicating full-page frames per state. Component States solve this elegantly - one component, all behaviors
Smart Animate Best Practices
Use consistent layer naming conventions throughout your file - Smart Animate's reliability depends on exact name matching. Adopt a naming convention like BEM: 'card__header', 'card__image'. Apply Smart Animate to transitions you specifically want animated - not all connections. High-traffic flows (loading → content, empty state → populated) benefit most from smooth Smart Animate transitions since they're seen most often. Test animations on real device speeds - Figma preview on a fast MacBook might look smooth, but 300ms at 60fps on a budget Android phone may stutter. Target 200-300ms with simple easing for optimal cross-device performance.
Tip
Tip
Practice Smart Animate Component States in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
Practice Task
Note
Practice Task - (1) Write a working example of Smart Animate Component States from scratch without looking at notes. (2) Modify it to handle an edge case (empty input, null value, or error state). (3) Share your solution in the Priygop community for feedback.

Common Mistake
Warning
A common mistake with Smart Animate Component States is skipping edge case testing - empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready ui ux code.
