Multicolor Selected Region - Bootstrap Slider by Seiyria

Question

Is it possible to make a multicolor "selected region" for the seiyria-bootstrap-slider?

Maybe someone is able to help me. I will attach below my project example, so u can try and test.

Multicolor example

 var minSliderValue = $("#ex11").data("slider-min");
            var maxSliderValue = $("#ex11").data("slider-max");

            $('#ex11').slider({
                ticks: [1, 2, 3, 5, 10, 25, 50, 100],
                ticks_positions: [0, 10, 20, 35, 50, 65, 82.5, 100],
                ticks_labels: ["1x", "2x", "3x", "5x", "10x", "25x", "50x", "100x"],
                ticks_snap_bounds: 1, //0.5
                ticks_tooltip: true,
                step: 1,
                max: 100, //JS script
                tooltip: 'always',
                value: 10,
                //focus: true,
                formatter: function (value) {
                    return value + 'x';
                },
            });

            $("#input-value").on("keyup", function () {
                var val = Math.abs(parseInt(this.value, 10) || minSliderValue);
                this.value = val > maxSliderValue ? maxSliderValue : val;
                $('#ex11').slider('setValue', val);
            });

            $("#ex11").slider();
            $("#ex11").on("slide", function (slideEvt) {
                $("#ex11SliderVal").text(slideEvt.value);
            });

            #ex11Slider .slider-selection {
                background: #FF8282;
            }

            #ex11Slider .slider-handle {
                background: red;
            }

You can use linear-gradient

https://developer.mozilla.org/en-US/docs/Web/CSS/linear-gradient()

var minSliderValue = $("#ex11").data("slider-min");
var maxSliderValue = $("#ex11").data("slider-max");

$('#ex11').slider({
  ticks: [1, 2, 3, 5, 10, 25, 50, 100],
  ticks_positions: [0, 10, 20, 35, 50, 65, 82.5, 100],
  ticks_labels: ["1x", "2x", "3x", "5x", "10x", "25x", "50x", "100x"],
  ticks_snap_bounds: 1, //0.5
  ticks_tooltip: true,
  step: 1,
  max: 100, //JS script
  tooltip: 'always',
  value: 10,
  //focus: true,
  formatter: function(value) {
    return value + 'x';
  },
});

$("#input-value").on("keyup", function() {
  var val = Math.abs(parseInt(this.value, 10) || minSliderValue);
  this.value = val > maxSliderValue ? maxSliderValue : val;
  $('#ex11').slider('setValue', val);
});

$("#ex11").slider();
$("#ex11").on("slide", function(slideEvt) {
  $("#ex11SliderVal").text(slideEvt.value);
});

body {
  background-color: #0f121b!important;
  color: #fff!important;
  padding: 4rem 2rem;
}

#ex11Slider {
  margin: 2rem;
  width: 70%;
}

.slider-tick,
.slider-handle {
  background-color: #ffffff!important;
  background-image: none!important;
  opacity: 1!important;
}

.slider-track {
  background-image: -webkit-gradient(linear, left top, right top, from(#129b6b), color-stop(#e5d02b), to(#b44b53))!important;
  background-image: -o-linear-gradient(left, #129b6b, #e5d02b, #b44b53)!important;
  background-image: linear-gradient(to right, #129b6b, #e5d02b, #b44b53)!important;
}

.slider-selection.tick-slider-selection {
  background-color: transparent!important;
  background-image: none!important;
}

.slider-track-high {
  background-color: #2d343e!important;
  background-image: none!important;
}

.slider-tick-label.label-is-selection {
  color: #4368bf!important;
  font-weight: 500!important;
