Input range with split colors using CSS - html

Question

Is it possible to restyle a input range to have different colors on the right and left side of the tracker just by CSS? This is what i have gotten so far.
input[type=range] {
margin: 10px 0;
margin: 50px;
width: 500px;
background: transparent;
-webkit-appearance: none;
}
input[type=range]::-webkit-slider-runnable-track {
height: 10px;
background: white;
border-radius: 5px;
}
input[type=range]::-webkit-slider-thumb {
-webkit-appearance: none;
border: none;
height: 25px;
width: 25px;
border-radius: 50%;
background: white;
border: 3px green solid;
margin-top: -7px;
}
input[type=range]:focus {
outline: none;
}
body {
background-color: green;
}
<input type="range" min="0" max="10" />

Answer 1

Yeah, you could use css gradient.
input[type=range]::-webkit-slider-runnable-track {
background: linear-gradient(to right, #000000 0%,#000000 50%,#ffffff 50%,#ffffff 100%,#ffffff 100%);
}

Answer 2

As far as I know it is not possible to do using only CSS.
Alternatively you can easily accomplish it with a tiny bit of javascript.
Use this: https://toughengineer.github.io/demo/slider-styler
for (let e of document.querySelectorAll('input[type="range"].slider-progress')) {
e.style.setProperty('--value', e.value);
e.style.setProperty('--min', e.min == '' ? '0' : e.min);
e.style.setProperty('--max', e.max == '' ? '100' : e.max);
e.addEventListener('input', () => e.style.setProperty('--value', e.value));
}
/*surrounding background color*/
body {
background: green;
}

input[type=range].styled-slider {
height: 2.2em;
-webkit-appearance: none;
/*added this property to generated CSS to match the surrounding background color*/
background: transparent;
/*specify desired width*/
width: 500px;
}
/*progress support*/
input[type=range].styled-slider.slider-progress {
--range: calc(var(--max) - var(--min));
--ratio: calc((var(--value) - var(--min)) / var(--range));
