Clank – An HTML/CSS Framework For Prototyping Native Mobile Apps
Clank is a free and open source HTML-CSS framework for easily prototyping native mobile or tablet apps.
It focuses on providing a consistent UI “without the the concern of mimicking a specific OS”.
The framework is component-based so that we can pick and use only the needed parts. And these components include buttons, forms, sliders, toggles and much more.
SCSS is used for styling and the layout can be skinned with ease by changing several variables.
There are also various “device wraps” bundled (iPhone, Nexus, iPad..) to quickly present the output in a realistic design.
