Responsive design adapts layouts automatically across screen sizes from mobile phones to desktop displays. Typography scales proportionally using configurable factors for tablet and mobile breakpoints. Navigation transforms into a burger menu system with four layout options including slide-out panels and fullscreen modes. Touch-friendly controls ensure proper tap target sizes for mobile interaction. Images resize and optimize automatically based on viewport dimensions, reducing bandwidth usage on mobile connections. The gallery system adjusts column counts and spacing for smaller screens while maintaining visual hierarchy. Content width and padding adapt to prevent horizontal scrolling and maintain readability. The mobile-first approach ensures functional parity across devices rather than treating mobile as a reduced experience.
