A UI Component Library (or UI Kit) is a collection of design elements used to create an interface for a website or mobile application. This library consists of components such as buttons, navigation bars, and forms, as well as other elements like icons, colors, and typography. This allows you to create a consistent, branded look and feel for your website or app.
A UI Component Library can be a great time-saver for designers, as it eliminates the need for them to create each design element from scratch. It also enables designers to create designs quickly and efficiently, as they can easily reuse existing components.
A UI Component Library can be used in a variety of tools, such as Sketch, Figma, or Adobe XD. It can also be used to create a style guide, which sets out the standards for designing elements such as buttons, navigation bars, and forms. This ensures that all elements are consistent, helping to give your website or app a professional, branded look.
