Movement applied to elements that brings interfaces to life and guides user attention through visual storytelling. Thoughtful animation improves usability by providing feedback, showing relationships between elements, and making interactions feel responsive. Framer offers powerful animation tools including appear effects, scroll-based triggers, and component variants with smooth transitions.

A mathematically defined curve used in vector graphics and animation, controlled by anchor points and handles that determine its shape. Understanding bezier curves helps create smooth, natural-feeling animations and custom easing functions. Framer's animation curves use bezier mathematics to control the acceleration and deceleration of motion.

The rate of change in an animation over time, controlling acceleration and deceleration for natural-feeling motion. Linear easing feels mechanical while ease-out mimics physical objects slowing from friction. Framer provides preset easing curves and custom bezier options to fine-tune animation feel.

A point in an animation timeline that defines specific property values, with the software interpolating values between keyframes. Keyframe animation gives precise control over complex motion sequences. Understanding keyframes helps you create sophisticated animations in Framer's advanced motion tools.

A JSON-based animation format that renders Adobe After Effects animations on the web with small file sizes and infinite scalability. Lottie animations are lightweight, vector-based, and highly customizable through JavaScript. Import Lottie files into Framer for sophisticated animations without performance penalties.

The use of animation and movement in interfaces to communicate, guide attention, and create engaging experiences. Thoughtful motion provides feedback, shows relationships, and adds personality. Balance motion benefits with accessibility concerns and performance impacts.

The animation or effect that occurs when navigating between pages, providing visual continuity. Page transitions can make navigation feel seamless and help users maintain context. Framer supports various transition effects between pages.

A scrolling effect where background elements move slower than foreground elements, creating an illusion of depth. Parallax adds visual interest and engagement but can impact performance and cause motion sickness. Use parallax sparingly and provide reduced-motion alternatives for accessibility.

An animation tool and runtime for creating interactive graphics that respond to user input in real time. Rive animations are lightweight and highly interactive, enabling complex state-driven animations. Import Rive files for sophisticated interactive elements.

The relative size of elements in relation to each other and the overall design, establishing hierarchy and emphasis. Scale creates visual drama—dramatically larger elements command attention while smaller ones recede. Consider how scale relationships change across breakpoints in responsive designs.

Animation properties that change continuously based on scroll position, creating smooth parallax and reveal effects. Scroll-linked animations tie element properties like opacity, scale, or position to scroll progress. Use sparingly for performance and respect reduced motion preferences.

Animations that play once when elements enter the viewport during scrolling, commonly used for section reveals. Scroll-triggered animations add polish and draw attention to content as it appears. Framer's appear effects provide scroll-triggered animation capabilities.

Physics-based animation that simulates natural spring-like motion with properties like stiffness, damping, and mass. Spring animations feel more natural than linear or bezier-based easing. Framer Motion powers Framer's spring animation capabilities.

The animated change between two states of an element, such as button hover effects or page navigation. Smooth transitions make interfaces feel polished and help users track changes. Keep transitions quick (200-400ms for UI elements) to maintain responsive feel.
