Responsive Website Design - Multi-device responsive layouts
Overview
Context & impact

Today's websites must work flawlessly on any device. I design and build responsive sites that deliver exceptional user experiences whether viewed on a phone, tablet, or desktop—combining visual design, interaction patterns, and performance optimization.

Problem

Organizations needed websites that not only looked professional but actually drove business results. Many existing sites were slow to load, difficult to navigate on mobile devices, and failed to guide visitors toward key actions.

  • Create layouts that adapt gracefully from 320px mobile screens to 4K displays.
  • Optimize page load times to reduce bounce rates and improve search rankings.
  • Design conversion-focused landing pages that guide visitors to take action.
Approach

I approached each project with a mobile-first mindset, designing for the smallest screens first and progressively enhancing for larger viewports. This ensured core content and functionality worked everywhere.

  • Conducted competitive analysis and user research to understand audience needs and expectations.
  • Designed responsive wireframes and high-fidelity mockups in Figma with multiple breakpoints.
  • Built sites using semantic HTML5, modern CSS (Grid, Flexbox, custom properties), and vanilla JavaScript.
  • Implemented responsive images with srcset/picture elements to optimize for different screen densities.
  • Tested across browsers (Chrome, Firefox, Safari) and devices (iOS, Android) to ensure consistent experiences.
Performance & Accessibility

Beautiful design doesn't matter if pages take forever to load or screen readers can't navigate them.

  • Optimized images, minified CSS/JS, and implemented lazy loading to achieve sub-2s load times.
  • Ensured keyboard navigation, proper heading hierarchy, and ARIA labels for accessibility.
  • Implemented proper color contrast ratios meeting WCAG AA standards.
  • Added structured data (schema.org) to improve search engine understanding.
Outcome
Mobile engagement Responsive designs increased mobile conversion rates by 40-60%.
Faster load times Performance optimization reduced bounce rates and improved SEO rankings.
Accessible by default WCAG-compliant sites expanded audience reach and reduced legal risk.
