Responsive fluid across devices.

Websites that feel native at every viewport — mobile-first development, fluid typography, container queries, and interactions tuned for touch, mouse, and keyboard. One codebase, every device, no embarrassing edge cases.

Overview

What it means to work with us.

Responsive is table stakes in 2026, but doing it well still takes craft. We design layouts that breathe between breakpoints, type that scales smoothly with viewport width, and interactions that adapt to input method. There is no separate mobile site, no separate tablet build — one codebase that adapts gracefully.

What we deliver

Capabilities & deliverables.

Every engagement is shaped to fit, but these are the building blocks we rely on.

01

Mobile-First Workflow

Designed and built at 375 pixels first, then progressively enhanced for tablet and desktop. Priority order matches user behavior.

02

Fluid Typography

Type scales smoothly with viewport using clamp and rem-based ratios. Never jumpy, always proportionate, always readable.

03

Container Queries

Components respond to their container size, not just the viewport. Layouts adapt to context, which matters more than ever.

04

Touch-First Interactions

44-pixel hit targets, swipe gestures where they help, and zero hover-only behavior. Accessible to thumbs, mice, and keyboards alike.

05

Cross-Device QA

Tested on real iOS Safari, Android Chrome, foldables, tablets, and large monitors. BrowserStack covers the long tail.

06

Performance Budget

Mobile networks dictate the budget. Lazy-loaded images, code-split routes, and prefetched critical assets keep things fast everywhere.

Why it works

The SD Technolabs difference.

Two decades of practice sharpened into a way of working that respects both craft and clock.

01

Real devices, not emulators

We test on actual phones — old ones, slow ones, weird ones. Issues found in DevTools rarely match what users see.

02

Core Web Vitals on mobile

Green LCP, CLS, and INP scores on mid-range Android, not just on a fast desktop. The harder bar to clear.

03

One codebase, every device

No mobile sites, no app banners pretending to be the site. Maintainable forever.

04

Accessible at every breakpoint

Touch, voice, keyboard, screen reader — every interaction model works at every size we ship.
