# mdInput
2+

Inputs are the basic input component of Material 2. The spec can be found [here](https://www.google.com/design/spec/components/text-fields.html).

7+
## Type
8+
9+
At the time of writing this README, the `[type]` attribute is copied to the actual `<input>` element in the `<md-input>`. Therefore, the valid types and behavior of those are the ones supported by your browser.
