 Material Components for the web is the successor to [Material Design Lite](https://getmdl.io/). In addition to implementing the [Material Design guidelines](https://material.io/design), it provides more flexible theming customization, not only in terms of color, but also typography, shape, states, and more. It is also specifically [architected](docs/code/architecture.md) for adaptability to various [major web frameworks](docs/framework-wrappers.md).
