A custom slider element. To get a basic style for the slider component, copy the CSS in the example - otherwise the slider will not be visible on render. To be visible, the gb-slider tag must be given a height, the .gb-slider__handle class must be given a height and width, and the component parts must be given background colors.


// index.js
const min = 0;
const max = 200;
const onChange = function(low, high) {
  low = low;
  high = high;
let low = min;
let high = max;

<gb-slider on-change="{ onChange }" low="{ low }" high="{ high }"></gb-slider>
/* styles.css */
gb-slider {
