Progressive Enhancement

Definition

Progressive enhancement is a web design strategy that emphasizes creating a basic level of user experience that is accessible to all users, regardless of their device or browser capabilities, and then progressively adding advanced features for those with better resources. This approach ensures that the core content is always accessible, while enhanced functionalities are layered on top for users with more capable systems. It fosters inclusivity and adaptability in web-based designs, particularly relevant in mobile-first strategies.
