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. See Mastering transitions and easing in Framer.

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.
