html - 将值添加到拨动拨动开关

我有这个拨动开关，如何更改为“是”或“否”。但是我可以将绿色更改为红色，但是向其中添加文本对我来说确实是一个挑战。如何向此滑块添加文本。当出现绿色时，它应该是，当出现红色时，它应该是。
我需要像链接中这样的开关

<style>
  .cmn-toggle {
    position: absolute;
    margin-left: -9999px;
    visibility: hidden;
  }
  .cmn-toggle + label {
    display: block;
    position: relative;
    cursor: pointer;
    outline: none;
    user-select: none;
  }
  input.cmn-toggle-round + label {
    padding: 2px;
    width: 120px;
    height: 60px;
    background-color: #dddddd;
    border-radius: 60px;
  }
  input.cmn-toggle-round + label:before,
  input.cmn-toggle-round + label:after {
    display: block;
    position: absolute;
    top: 1px;
    left: 1px;
    bottom: 1px;
    content: "";
  }
  input.cmn-toggle-round + label:before {
    right: 1px;
    background-color: #f1f1f1;
    border-radius: 60px;
    transition: background 0.4s;
  }
  input.cmn-toggle-round + label:after {
    width: 58px;
    background-color: #fff;
    border-radius: 100%;
    box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
    transition: margin 0.4s;
  }
  input.cmn-toggle-round:checked + label:before {
    background-color: #8ce196;
  }
  input.cmn-toggle-round:checked + label:after {
    margin-left: 60px;
  }

 HTML code:

    <div class="switch">
      <input id="cmn-toggle-1" class="cmn-toggle cmn-toggle-round" type="checkbox">
      <label for="cmn-toggle-1"></label>
    </div>

最佳答案

您只需将“内容”更改为“是”和“否”即可

.cmn-toggle {
    position: absolute;
    margin-left: -9999px;
    visibility: hidden;
  }
  .cmn-toggle + label {
    display: block;
    position: relative;
    cursor: pointer;
    outline: none;
    user-select: none;
  }
  input.cmn-toggle-round + label {
    padding: 2px;
    width: 120px;
    height: 60px;
    background-color: #dddddd;
    border-radius: 60px;
  }
  input.cmn-toggle-round + label:before,
  input.cmn-toggle-round + label:after {
    display: block;
    position: absolute;
    top: 1px;
    left: 1px;
    bottom: 1px;
      text-align:center;
  }
  input.cmn-toggle-round + label:before {
    right: 1px;
    background-color: #f1f1f1;
    border-radius: 60px;
    transition: background 0.4s;
  }
  input.cmn-toggle-round + label:after {
    width: 58px;
    background-color: #fff;
    border-radius: 100%;
    box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
    transition: margin 0.4s;
      line-height:390%;
      content:"NO";
  }
  input.cmn-toggle-round:checked + label:before {
    background-color: #8ce196;
      content:"";
  }
  input.cmn-toggle-round:checked + label:after {
    margin-left: 60px;
      content:"YES";
  }

.switch{
    display:flex;
    margin:auto;
}
