Liquid Glass is a new design material introduced by Apple, which combines the optical qualities of glass with the fluidity of liquid. It is a dynamic and adaptive material that enhances the look and feel of apps and system experiences across Apple's platforms. Liquid Glass is designed to create a more fluid and immersive interaction experience, bringing a new level of depth and vitality to user interfaces.
The material dynamically adapts to the content underneath, changing from light to dark, and provides a distinct functional layer that floats above the app content. It is used to enhance controls and navigational elements, making them feel more alive and responsive. Liquid Glass is applied across various components, such as toggles, segmented pickers, sliders, and app icons, to create a delightful and visually appealing experience.
