| Material design: [Sliders](https://www.google.com/design/spec/components/sliders.html) |
| |
| `paper-slider` allows user to select a value from a range of values by |
| moving the slider thumb. The interactive nature of the slider makes it a |
| great choice for settings that reflect intensity levels, such as volume, |
| brightness, or color saturation. |
| |
| Example: |
| |
| <paper-slider></paper-slider> |
| |
| Use `min` and `max` to specify the slider range. Default is 0 to 100. |
| |
| Example: |
| |
| <paper-slider min="10" max="200" value="110"></paper-slider> |
| |
