What is a mobile-first website design and why does it matter for Indian users?

Mobile-first design prioritizes the mobile user experience in design and development decisions, then adapts for larger screens — the opposite of desktop-first thinking. In India, 75-80% of internet access is via mobile (Reliance Jio, Airtel 4G, BSNL 4G), making mobile-first not just a best practice but a business necessity. Mobile-first principles: touch-friendly buttons (minimum 44x44px tap targets), font sizes readable without zoom (16px minimum body text), no horizontal scrolling (all content within viewport width), fast loading on 4G (under 3 seconds on slow 4G), simplified navigation (hamburger menu, bottom navigation bar), and forms optimized for mobile keyboards (input type=tel for phone numbers, type=email for email). Test your site: Chrome DevTools (F12) > Toggle Device Toolbar > select a popular Indian phone (Redmi, Samsung Galaxy). Google prioritizes mobile experience in rankings (Mobile-First Indexing).
