Mobile-first is a design and development approach that prioritizes creating a user experience optimized for mobile devices before adapting it to larger screens like desktop computers. This approach acknowledges the increasing use of mobile devices for accessing websites and applications.
Developers and designers focus on mobile devices' smaller screens, touch interfaces, and varied connectivity conditions. They ensure that content, navigation, and functionality work seamlessly on mobile platforms, and then scale up for larger screens.
For instance, when designing a website using a mobile-first approach, designers start with the mobile layout, ensuring that content is readable and accessible on small screens. They then progressively enhance the design for larger screens, rather than trying to scale down a desktop-focused design.
