<div class="slider-container">
  <input type="range" id="myRange" min="0" max="100" value="50">
</div>

.slider-container {
  width: 300px;
  margin: 20px;
}

input[type=range] {
  -webkit-appearance: none; /* 移除默认样式 */
  width: 100%;
  height: 5px;
  background: #d3d3d3;
  outline: none;
  opacity: 0.7;
  -webkit-transition: .2s;
  transition: opacity .2s;
}

input[type=range]::-webkit-slider-thumb {
  -webkit-appearance: none;
  appearance: none;
  width: 20px;
  height: 20px;
  background: #4CAF50;
  cursor: pointer;
}

input[type=range]::-moz-range-thumb {
  width: 20px;
  height: 20px;
  background: #4CAF50;
  cursor: pointer;
}

const slider = document.getElementById('myRange');

slider.addEventListener('input', function() {
  console.log(this.value); // 输出当前滑块的值
});
