Mobile-First Design: The New Standard for Web Development in 2025

As we step into 2025, mobile-first design has cemented its place as a fundamental approach in web development. With more than 60% of global web traffic coming from mobile devices, creating a seamless mobile experience is no longer optional but a necessity. This design philosophy ensures that websites are optimized for smaller screens first before scaling up for larger devices.

Design is not just what it looks like and feels like. Design is how it works. – Steve Jobs
