重新构思的标题:如何只对盒子阴影应用溢出效果

<p>我正在尝试构建一个输入范围滑块条,但是我遇到了一个问题。</p> <p> <pre class="brush:css;toolbar:false;">body { justify-content: center; align-items: center; min-height: 100vh; background: #151515; } #rangeValue { position: relative; display: block; font-size: 6em; color: #999; font-weight: 400; } .range { background: linear-gradient(-45deg, #ee7752, #e73c7e, #23a6d5, #23d5ab) !important; width: 400px; height: 5px; -webkit-appearance: none; background: #111; outline: none; border-radius: 15px; box-shadow: inset 0 0 5px rgba(0, 0, 0, 1); } .range::-webkit-slider-thumb { -webkit-appearance: none; width: 15px; height: 15px; border-radius: 50%; background: blue; cursor: pointer; box-shadow: -507px 0 0 500px red; }</pre> <pre class="brush:html;toolbar:false;"><div> <span id="rangeValue">0</span> <Input class="range" type="range" name "" value="0" min="0" max="1000"></Input> </div></pre> </p> <p>问题是:我希望这个大红色区域在绘制时仍然保持在输入滑块内。唯一的解决方案是将<code>overflow: hidden</code>应用于<code>.range</code>,但我将失去蓝点按钮。 是否有一种方法可以仅将<code>overflow: hidden</code>应用于<code>box-shadow</code>?或者有其他方法使其正常工作的线索吗?</p> <p>最终结果应该是这样的 =></p> <p><img src="/uploads/20230822/169264211664e3ab441b49a.png" alt=" final result " /></p> <p>谢谢。</p>

    我不确定这是否有帮助,但这是我进行的重构。也许你可以做一些修改以适应你的任务。

        <div>
        <span id="rangeValue">0</span>
        <Input type="range" name="" id="range" value="0" min="0" max="100"></Input>
    </div>
    </body>
      
      <script src=""></script>
    </html>

    CSS

    body {
        justify-content: center;
        align-items: center;
        min-height: 100vh;
        background: #151515;
    }
    #rangeValue {
        position: relative;
        display: block;
        font-size: 6em;
        color: #999;
        font-weight: 400;
    }
    
    /* Input Thumb */
    input[type="range"]::-webkit-slider-thumb {
      -webkit-appearance: none;
      height: 20px;
      width: 20px;
      border-radius: 50%;
      background: #ff4500;
      cursor: ew-resize;
      box-shadow: 0 0 2px 0 #555;
      transition: background .3s ease-in-out;
    }
    
    input[type="range"]::-moz-range-thumb {
      -webkit-appearance: none;
      height: 20px;
      width: 20px;
      border-radius: 50%;
      background: #ff4500;
      cursor: ew-resize;
      box-shadow: 0 0 2px 0 #555;
      transition: background .3s ease-in-out;
    }
    
    input[type="range"]::-ms-thumb {
      -webkit-appearance: none;
      height: 20px;
      width: 20px;
      border-radius: 50%;
      background: #ff4500;
      cursor: ew-resize;
      box-shadow: 0 0 2px 0 #555;
      transition: background .3s ease-in-out;
    }
    
    
    /* Input Track */
    input[type=range]::-webkit-slider-runnable-track  {
      -webkit-appearance: none;
      box-shadow: none;
      border: none;
      background: transparent;
    }
    
    input[type=range]::-moz-range-track {
      -webkit-appearance: none;
      box-shadow: none;
      border: none;
      background: transparent;
    }

    JS

    const rangeInputs = document.querySelectorAll('input[type="range"]')
    
    function handleInputChange(e) {
      let target = e.target
      if (e.target.type !== 'range') {
        target = document.getElementById('range')
      }
      
      const min = target.min
      const max = target.max
      const val = target.value
      
      target.style.backgroundSize = (val - min) * 100 / (max - min) + '% 100%'
    }
    
    rangeInputs.forEach(input => {
      input.addEventListener('input', handleInputChange)
    })

    你可以根据自己的喜好进行调整。 希望这有所帮助。
