Responsive design

Responsive web design uses flexible grids, flexible images, and CSS media queries to adapt a single website to any screen size. One URL, one codebase, every device.

Responsive vs separate mobile site

A separate mobile site (m.example.com) requires duplicate content, separate maintenance, and splits your SEO signals. Google recommends responsive design as the best practice � it is simpler, faster to maintain, and keeps all link equity on one URL.

Responsive design uses the same HTML and CSS across all devices. Media queries apply different styles at different screen widths. No redirects, no device detection, no maintenance overhead.

Key principles

Fluid grids � Use relative units (%, rem, vw, fr) instead of fixed pixel widths. A two-column layout on desktop becomes a single column on mobile.

Flexible images � Images scale within their containers using max-width: 100%. Different image sizes are served at different breakpoints using srcset.

Media queries � CSS breakpoints at common screen widths (typically 480px, 768px, 1024px) adjust typography, layout, and navigation. Build mobile-first: start with the mobile layout and add complexity at larger screens.

Common responsive failures

Fixed-width containers that overflow the screen. Tables that force horizontal scrolling. Navigation menus that do not collapse on small screens. Videos embedded with fixed dimensions. These are flagged in every site audit.

Audit check: We test your site at 320px, 768px, 1024px, and 1440px widths. Any broken layouts, overflow issues, or unresponsive elements are documented with screenshots and fix instructions.
