Application Shell Model

The Application Shell Model is a web design approach that prioritizes loading the core parts of a website’s interface quickly, such as menus, logos, and layout elements. These parts form the “shell” or foundation that users see first, allowing the site to look and respond fast. As users interact, dynamic content loads in the background, filling in the details seamlessly. This approach improves user experience by making websites feel faster and more responsive, especially on slower connections, by focusing on delivering essential components immediately and loading less critical content afterward.
