Ratchet is a web-based mobile UI framework and component-based library designed to create responsive mobile application interfaces. It provides a CSS mobile layout system that allows for the development of application frontends using standard web technologies.
The framework focuses on mobile app interface design and rapid prototyping, utilizing pre-styled visual elements to ensure consistent styling across various screen sizes and resolutions.
The system employs a CSS-only approach to define interactive states and layouts, incorporating a grid-based responsive layout and utility-first stylesheets for spacing and alignment. It renders interfaces using standard HTML elements styled to mimic native mobile application components.
