An animation that plays when an element first becomes visible on screen, typically as the user scrolls down the page. These effects add polish and draw attention to content as it enters the viewport. Framer provides various appear effects like fade, slide, scale, and blur that can be customized for timing, delay, and easing.

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.

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. See Mastering transitions and easing in Framer. See Using the Loop Effect in Framer.

Web Content Accessibility Guidelines—international standards defining how to make web content accessible to people with disabilities. WCAG compliance is increasingly required legally and expands your potential audience. Aim for at least WCAG 2.1 AA conformance.

A mathematical proportion of approximately 1:1.618 found throughout nature and art, often used to create aesthetically pleasing layouts. The golden ratio can guide element sizing, spacing, and composition decisions. While not a strict rule, it provides a starting point for harmonious proportions.
