-Material design: [Checkbox](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-checkbox)
-
-`paper-checkbox` is a button that can be either checked or unchecked.  User
-can tap the checkbox to check or uncheck it.  Usually you use checkboxes
-to allow user to select multiple options from a set.  If you have a single
-ON/OFF option, avoid using a single checkbox and use `paper-toggle-button`
-instead.
-
-Example:
-
-    <paper-checkbox>label</paper-checkbox>
-
-    <paper-checkbox checked> label</paper-checkbox>
-
-### Styling
-
-The following custom properties and mixins are available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-checkbox-unchecked-background-color` | Checkbox background color when the input is not checked | `transparent`
-`--paper-checkbox-unchecked-color` | Checkbox border color when the input is not checked | `--primary-text-color`
-`--paper-checkbox-unchecked-ink-color` | Selected/focus ripple color when the input is not checked | `--primary-text-color`
-`--paper-checkbox-checked-color` | Checkbox color when the input is checked | `--primary-color`
-`--paper-checkbox-checked-ink-color` | Selected/focus ripple color when the input is checked | `--primary-color`
-`--paper-checkbox-checkmark-color` | Checkmark color | `white`
-`--paper-checkbox-label-color` | Label color | `--primary-text-color`
-`--paper-checkbox-label-checked-color` | Label color when the input is checked | `--paper-checkbox-label-color`
-`--paper-checkbox-label-spacing` | Spacing between the label and the checkbox | `8px`
-`--paper-checkbox-label` | Mixin applied to the label | `{}`
-`--paper-checkbox-label-checked` | Mixin applied to the label when the input is checked | `{}`
-`--paper-checkbox-error-color` | Checkbox color when invalid | `--error-color`
-`--paper-checkbox-size` | Size of the checkbox | `18px`
-`--paper-checkbox-ink-size` | Size of the ripple | `48px`
-`--paper-checkbox-margin` | Margin around the checkbox container | `initial`
-`--paper-checkbox-vertical-align` | Vertical alignment of the checkbox container | `middle`
-
-This element applies the mixin `--paper-font-common-base` but does not import `paper-styles/typography.html`.
-In order to apply the `Roboto` font to this element, make sure you've imported `paper-styles/typography.html`.

-Material design: [Sliders](https://www.paper.com/design/spec/components/sliders.html)
-
-`paper-diff-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-diff-slider></paper-diff-slider>
-
-Use `min` and `max` to specify the slider range.  Default is 0 to 100.
-
-Example:
-
-    <paper-diff-slider min="10" max="200" value="110"></paper-diff-slider>
-

-## Styling
-
-The default color values respect the material specifications. For basic configuration, just defines the `--primary-color` for your app.
-
-The stepper has a complexe interface so many custom properties are available, use them this way :
-
-```html
-<style is="custom-style">
-
-  paper-stepper {
-    --paper-stepper-custom-property: value;
-  }
-
-  paper-step {
-    --paper-step-custom-property: value;
-  }
-
-</style>
-
-<paper-stepper>
-  <paper-step></paper-step>
-  <paper-step></paper-step>
-</paper-stepper>
-```
-
-Note, for sizing the stepper and steps depending on the layout, use the following instead of setting 'height' and 'max-height' :
-- `--paper-stepper-horizontal-opened-height`
-- `--paper-stepper-vertical-max-height`
-- `--paper-vertical-step-max-height`
-
