Screen Resolutions and Device Types
Screen resolutions vary significantly by device type, influencing responsive design strategies. The most common desktop resolution is 1920×1080 (Full HD), representing 24.1% of desktop users, followed by 1366×768 (10.5%) and 1536×864 (10.8%).

Responsive Design and User Behavior
Modern web design prioritizes responsive layouts using relative units (%, rem, vh, vw) rather than fixed pixel dimensions to ensure compatibility across diverse screen sizes. Key breakpoints for responsive design include ≤480px (mobile), 768px (tablet portrait), 1024px (tablet landscape), and 1280px+ (desktop).
