|
| +`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:

|

|
| + paper-slider {

|

|
| +To change the slider pin color:
|
| +
|
| + paper-slider {
|
| + --paper-slider-pin-color: #0f9d58;
|

|
| +
|

|
| +
|
| + paper-slider {
|
| + --paper-slider-pin-font-color: #0f9d58;
|

|
| +
|
| +To change the slider secondary progress bar color:
|
| +
|
| + paper-slider {
|
| + --paper-slider-secondary-color: #0f9d58;
|
| + }
|
| +
|
| +To change the slider disabled active color:
