Creenv slider

A simple and fully customizable slider, in native javascript. No need for complexity.

Usage

``js
var Slider = require("@creenv/slider");

var callbackChange = function (val) {
console.log("value has changed: "+val);
}

var callbackChangeFinished = function (val) {
console.log("user has finished sliding: "+val);
}

var mySlider = new Slider(0, 100, 0.5, 10, callbackChange, callbackChangeFinished);
document.body.appendChild(mySlider.dom);
`

Custom the style

The css of the slider will be inserted into the < head > tags, within < style > tags identified by id="creenv-slider-style", right at the beginning. You can overwrite any of these rules to apply you own rules. Only 3 classes are used by @creenv/slider:

| Class | What ? |
|---|---|
| .creenv-slider-container | The container of the whole slider. Its background-color will be the background color of the slider |
| .creenv-slider-progress | The progress bar. Its width will be programatically set to match the value of the slider |
| .creenv-slider-cursor | The draggable cursor |
