27 CSS App Design Examples
This collection demonstrates how to build native-like web applications using only CSS. Rigid App Shells based on Grid and Flexbox are combined with scroll-snap physics to mimic iOS and Android behavior, while env(safe-area-inset-*) ensures a perfect fit on screens with notches. Complex UI elements like modals and drawers are implemented via :checked and :target pseudo-classes, completely eliminating the need for JavaScript. Furthermore, CSS variables enable seamless theming and Dark Mode support, creating a cohesive and performant user experience.
