Web and app design are crucial elements in creating a positive user experience. Design involves not only aesthetics but also functionality and usability. It encompasses layout, navigation, color schemes, and visual elements that contribute to a cohesive and visually appealing interface. Web design focuses on websites accessed through browsers, while app design pertains to the user interface and experience within mobile applications. Both areas emphasize creating intuitive, user-friendly designs that enhance the overall usability of digital platforms.
