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.

The visual appearance of an interactive element when it receives keyboard focus, which is critical for accessibility. Focus states must remain clearly visible; do not remove them without providing an equally visible replacement. A strong focus style improves usability for keyboard and assistive-technology users.

User Interface—the visual elements and interactive components through which users engage with a product. Good UI is intuitive, consistent, and aligned with user expectations and mental models. UI design balances aesthetic appeal with functional usability.

User Experience—the overall experience a person has when using a product, encompassing usability, accessibility, and emotional response. Good UX anticipates user needs and removes obstacles to goal completion. UX extends beyond UI to include performance, content clarity, and trust signals.

A minimalist design style emphasizing clean shapes, bright colors, and two-dimensional elements without shadows, gradients, or textures. Flat design emerged as a reaction to skeuomorphism and dominates modern digital interfaces. While visually clean, ensure sufficient visual hierarchy and affordances for usability.

Established usability principles used to evaluate interfaces, such as visibility of system status, error prevention, and user control. Heuristic evaluation helps identify usability problems efficiently without user testing. Apply Nielsen’s 10 heuristics or similar frameworks to audit your designs.

Inclusion is a design principle focused on creating experiences that are welcoming, usable, and respectful for diverse users and contexts.
