UI button systems play a critical role in guiding user interactions and facilitating navigation within your interface. Learn how to design button systems that are visually distinct, consistent, and intuitive to use. Define styles for different button states, such as default, hover, and active, to provide visual feedback to users. Dive into Figma's component library to create reusable button components that can be easily customized and scaled across your designs. Consider accessibility principles when designing UI button systems, ensuring that buttons are sufficiently large and have enough contrast for users with disabilities. By designing UI button systems effectively, you can create interfaces that are not only visually appealing but also user-friendly and accessible to all.
