Slider from RightToLeft

I would like to have a slider with value 100 on the left and value 0 on the right side. It’s color temperature, and I want the yellow/warm tones (= cold black body) on the left. I know how to change the linear-gradient to “to left” - it’s about the values.
Tried with “rightToLeft: true” but didn’t get any effect.

#slider-amb .rz-bar { background: linear-gradient(to right, #80ffff, #ffffff, #ffff80); height: 10px; } #slider-amb .rz-selection { background: transparent; } #slider-amb .rzslider .rz-pointer { width: 5px; height: 32px; top: auto; bottom: -16px; background-color: #212121; border-top-left-radius: 1px; border-top-right-radius: 1px; } #slider-amb .rzslider .rz-pointer:after { display: none; }
