What makes your responsive development different from others?
Our mobile-first approach combined with component-based architecture ensures not just responsive design, but truly adaptive interfaces.

Every interface is tested across 50+ device configurations to guarantee flawless functionality.
How do you ensure cross-browser compatibility?
We maintain an extensive testing lab with current and legacy browsers across Windows, macOS, iOS, and Android. Our development process includes automated browser testing, manual verification on physical devices, and progressive enhancement techniques. We support all major browsers and provide graceful degradation for older versions while maintaining core functionality.
Can you retrofit our existing website to be responsive?
Absolutely. We specialize in both new responsive builds and retrofitting existing websites. Our team analyzes your current codebase, identifies optimization opportunities, and implements responsive design while preserving your existing functionality and SEO rankings. The process typically takes 30-40% less time than building from scratch.
What frameworks and technologies do you use?
We use modern frameworks including React, Vue.js, and Angular, combined with advanced CSS technologies like Grid, Flexbox, and Container Queries.

All code follows current web standards and accessibility guidelines for maximum compatibility and maintainability.
How do you handle performance on mobile devices?
Mobile performance is prioritized from day one with techniques like critical CSS inlining, image optimization with WebP/AVIF formats, lazy loading, and efficient JavaScript bundling. We implement service workers for caching, use CDN for asset delivery, and optimize for Core Web Vitals. Target load times are under 3 seconds on 3G connections.
