输入范围滑块左侧的颜色与 React with ref.current.style 中滑块右侧的颜色不同？

Question

我一直在尝试将 input[type='range'] 溢出设置为隐藏，但是由于 input[type='range'] 溢出设置为隐藏，因此无法将拇指放大几 px，所以我正在尝试在组件本身内实现一些逻辑，而不是运气。

codesandbox

js:

const Slide3 = (props) => {


  const slider = useRef();

  const min = slider.min;
  const max = slider.max;
  const value = slider.value;

  if (slider.current) {
    // loaded
    slider.current.style.background = `linear-gradient(to right, red 0%, red ${
      ((value - min) / (max - min)) * 100
    }%, #DEE2E6 ${((value - min) / (max - min)) * 100}%, #DEE2E6 100%)`;

    slider.current.oninput = function () {
      slider.current.style.background = `linear-gradient(to right, red 0%, red ${
        ((this.value - this.min) / (this.max - this.min)) * 100
      }%, #DEE2E6 ${
        ((this.value - this.min) / (this.max - this.min)) * 100
      }%, #DEE2E6 100%)`;
    };
  }

  return (
    <div className="slide-3">
      <div className="sliders-container">
        {' '}
        <Slider
          name="Thickness"
          id="thickness-slider"
          min={0.01}
          max={0.1}
          step={0.01}
          refs={slider}
        />
        <Slider name="Length" id="length-slider" min={120} max={150} step={1} />
      </div>
    </div>
  );
};

css：

input[type="range"] {
  -webkit-appearance: none;
  -moz-appearance: none;
  width: 600px;
  height: 15px;
  padding: 0;
  border-radius: 20px;
  outline: none;
  cursor: pointer;
  background-color: rgb(220, 220, 220);
}

input[type="range"]::-webkit-slider-thumb {
  -webkit-appearance: none;
  -moz-appearance: none;
  -webkit-border-radius: 100px;
  /*30x30px adjusted to be same as 28x28px on moz*/
  height: 30px;
  width: 30px;
  border-radius: 100px;
  background: #ffffff;
}

我不确定你到底想做什么。

您可以查看此工具：https://toughengineer.github.io/demo/slider-styler
它使用一些 javascript 生成 CSS 以设置 <input> 范围滑块的样式，并带有进度指示等。

这是一个例子：

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));
}

input[type=range].styled-slider.slider-progress {
