-`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>
-
-### Styling
-
-The following custom properties and mixins are available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-slider-bar-color` | The background color of the slider | `transparent`
-`--paper-slider-active-color` | The progress bar color | `--google-blue-700`
-`--paper-slider-secondary-color` | The secondary progress bar color | `--google-blue-300`
-`--paper-slider-knob-color` | The knob color | `--google-blue-700`
-`--paper-slider-disabled-knob-color` | The disabled knob color | `--google-grey-500`
-`--paper-slider-pin-color` | The pin color | `--google-blue-700`
-`--paper-slider-font-color` | The pin's text color | `#fff`
-`--paper-slider-disabled-active-color` | The disabled progress bar color | `--google-grey-500`
-`--paper-slider-disabled-secondary-color` | The disabled secondary progress bar color | `--google-grey-300`
