Responsive Design

Responsive design serves optimal layouts for PCs, tablets, and smartphones from a single HTML document, using CSS media queries to adjust columns, fonts, images, and navigation based on screen width.

For QR code landing pages, responsive design is not optional - it is mandatory. The vast majority of QR code scans come from smartphones. A desktop-optimized page behind a QR code means unreadable text, untappable buttons, and horizontal scrolling - directly increasing post-scan bounce rates.

Key considerations for QR code landing pages: place the most important information and CTA in the first viewport (visible without scrolling); ensure tap targets meet minimum sizes (44x44pt Apple, 48x48dp Google); optimize loading speed for mobile connections.

Google's mobile-first indexing means mobile page quality directly affects search rankings. Responsive design quality determines whether QR code traffic also improves SEO performance.
