What is mobile-first design?

Designing for the smallest screen first, then adding complexity for larger screens. This ensures the mobile experience is not an afterthought and forces prioritization of essential content.

How many breakpoints should I define?

Typically 3–5: mobile ( 1280px). The exact values depend on your content and layout needs.

Responsive Design Explained

One codebase, every screen size — the mobile-first approach that ensures great UX on any device.

Responsive Design

A web design approach where layouts, images, and UI elements automatically adapt to the screen size and orientation of the device being used.

Explanation

Responsive design uses CSS media queries, flexible grids, and fluid images to create a single codebase that works on phones, tablets, and desktops. The mobile-first approach starts by designing for the smallest screen and progressively enhancing for larger ones. Key techniques include responsive typography, flexible images, breakpoint-based layouts, and touch-friendly interactive elements. With over 60% of web traffic coming from mobile devices, responsive design is a baseline requirement.

Bookuvai Implementation

Every Bookuvai frontend is built mobile-first with responsive design. We use MUI's responsive grid system, define breakpoints for xs/sm/md/lg/xl, test on real devices, and include mobile-specific UX patterns (bottom sheets, swipe gestures, touch targets). Every milestone delivery is tested on mobile before approval.
