The MDL components are created with CSS, JavaScript, and HTML. You can use the components to construct web pages and web apps that are attractive, consistent, and functional. Pages developed with MDL will adhere to modern web design principles like browser portability, device independence, and graceful degradation.
The MDL component library includes new versions of common user interface controls such as buttons, check boxes, and text fields, adapted to follow Material Design concepts. The library also includes enhanced and specialized features like cards, column layouts, sliders, spinners, tabs, typography, and more. MDL is free to download and use, and may be used with or without any library or development environment (such as [Web Starter Kit](https://developers.google.com/web/starter-kit/)). It is a cross-browser, cross-OS web developer's toolkit that can be used by anyone who wants to write more productive, portable, and — most importantly — usable web pages.
