Mobile-First vs Desktop-First Approach
Understand the difference between mobile-first and desktop-first design strategies.
What is Responsive Design?
Responsive web design creates layouts that adapt to any screen size — from small smartphones to large desktop monitors — using fluid grids, flexible images, and CSS media queries.
Mobile-First Design
In a mobile-first approach, you write base CSS for small screens, then use min-width media queries to progressively add complexity for larger screens.
/* Base styles: mobile */
.nav { flex-direction: column; }
/* Tablet and up */
@media (min-width: 768px) {
.nav { flex-direction: row; }
