Google's Material Design is a design language developed by Google that aims to create a unified experience across all platforms and devices. It emphasizes the use of grid-based layouts, responsive animations, and depth effects such as lighting and shadows to provide a sense of realism. This approach helps users understand how elements interact and behave within an interface. Material Design also promotes the use of bold colors, typography, and imagery to enhance visual appeal and usability. By following these guidelines, designers can create intuitive and engaging applications that feel consistent, making it easier for users to navigate and interact with digital products.
