Fluent Design is a design system developed by Microsoft that emphasizes a clean, modern aesthetic across digital interfaces. It focuses on creating a seamless user experience by incorporating depth, light, and motion, making applications feel more intuitive and engaging. The design principles aim to enhance usability on various devices, from desktops to mobile phones. Key elements of Fluent Design include the use of acrylic materials for transparency, responsive layouts that adapt to different screen sizes, and the integration of natural movement to guide users. This approach not only improves visual appeal but also fosters a more immersive interaction with technology.
