-`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 slider: |
- |
-To change the slider progress bar color: |
- |
- paper-slider::shadow #sliderBar::shadow #activeProgress { |
- background-color: #0f9d58; |
- } |
- |
-To change the slider knob color: |
- |
- paper-slider::shadow #sliderKnobInner { |
- background-color: #0f9d58; |
- } |
- |
-To change the slider pin color: |
- |
- paper-slider::shadow #sliderKnobInner::before { |
- background-color: #0f9d58; |
- } |
- |
-To change the slider pin's value: |
- |
- paper-slider::shadow #sliderKnobInner::after { |
- color: #0f9d58 |
- } |
- |
-To change the slider secondary progress bar color: |
- |
- paper-slider::shadow #sliderBar::shadow #secondaryProgress { |
- background-color: #0f9d58; |
- } |
