Feature Detection: Use feature detection techniques to identify the capabilities of the user's device or browser. By detecting what features are available, the design can adapt and provide an appropriate user experience that suits the user's environment.
-
Responsive Design: Enable the layout and content to adapt and adjust based on the user's screen size and device capabilities. This ensures that the user experience remains optimal, regardless of the device being used.
