javascript - 如何有一个开关，同时显示一开一关？

Question

我有一个开关，希望一个显示为关闭(灰色)，一个显示为打开(蓝色)，默认为打开。在这种特定情况下，我希望第一行具有蓝色“开启”元素，第二行和第三行将切换开关显示为关闭或灰色。

我已经尝试在 css 中添加额外的元素，但到目前为止没有任何效果。

.switch {
  position: relative;
  display: inline-block;
  width: 38px;
  height: 22px;
}

.switch input {
  display: none;
}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #98B3DD;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 16px;
  width: 16px;
  left: 3px;
  bottom: 3px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:focus+.slider {
  box-shadow: 0 0 1px rgb(221, 223, 235);
}

.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;
}

我想我找到了解决方案，代码中的注释解释了我所做的更改。

.switch {
  position: relative;
  display: inline-block;
  width: 38px;
  height: 22px;
}

.switch input {
  display:none;
}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #98B3DD;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 16px;
  width: 16px;
  left: 3px;
  bottom: 3px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:focus + .slider {
    box-shadow: 0 0 1px rgb(221, 223, 235);
}

.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;
}



/* ADDED THIS BELOW */ 

input:checked + .slider:before {
  -webkit-transform: translateX(16px);
  -ms-transform: translateX(16px);
  transform: translateX(16px);
}

input:checked + .slider {
  background-color: blue;
}

<!-- In the input tag I added the word *checked* for Device 1  and left it out for Device 2 and Device 3 -->
