Question

是否可以通过CSS重新设置输入范围以在跟踪器的右侧和左侧具有不同的颜色？这就是我到目前为止所获得的。

＆＃13;

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

是的，你可以使用css渐变。

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

Answer 2

据我所知，不可能只使用 CSS。

或者，您可以使用一点点 javascript 轻松完成它。
使用这个：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;
}

/*generated with Input range slider CSS style generator (version 20201223)
https://toughengineer.github.io/demo/slider-styler*/
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));
  --sx: calc(0.5 * 2em + var(--ratio) * (100% - 2em));
}

input[type=range].styled-slider:focus {
  outline: none;
}

/*webkit*/
input[type=range].styled-slider::-webkit-slider-thumb {

  margin-top: calc(max((1em - 1px - 1px) * 0.5,0px) - 2em * 0.5);
  -webkit-appearance: none;
}

input[type=range].styled-slider::-webkit-slider-runnable-track {
