Google is bringing its popular Material Design UI introduced in Android Lollipop to static websites.
Material Design Lite (MDL)  GitHub project, lets Web developers add a Material Design look and feel to static content websites. The Material Design implementation includes components of vanilla CSS, HTML and JavaScript, but doesn’t rely on any JavaScript frameworks or libraries.
MDL is optimized for cross-device use, progressive enhancement and “graceful degredation” in older browsers. The components can be used to construct Web pages and Web apps with consistent, functional design that adhere to modern Web design principles including browser portability and device independence. The implementation currently supports Android, Chrome, Firefox, Opera, Safari, mobile Safari and Internet Explorer 9, 10 and 11.
To get started, those interested can visit the get MDL site. Alternatively, developers can test one of Google's examples on CodePen. MDL includes a host of rich components: design buttons, text-fields, tooltips, spinners, and more. Its responsive grid and breakpoints conform to new material design adaptive UI guidelines.

Google has published a FAQ section for common questions. However, Google encourages developers to reach out to the developer team on GitHub or Stack Overflow with specific questions and comments.
