Question

我有一个切换按钮，我正在尝试使用复选框和纯CSS。我想要得到的最终结果是这样的 https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_switch

但是从不同的来源尝试后，我最终还是做了这样的事情

.slide-btn-alt .slide-btn-content .slide-btn-handle {
  position: static;
  width: 50%;
  border-radius: 0;
  background: none;
  text-align: center;
  -webkit-transform: translateX(0);
  -ms-transform: translateX(0);
  transform: translateX(0);
}

我面临的问题是我无法转换方向，我在w3schools上选中的内容显示为On / checked，左侧为文本，右侧为滑块，而Off / unChecked，右侧为文本，左侧滑块。而我最终所做的却显示出完全相反的行为。

这是因为我的按钮就像吗？

关闭||手柄||打开

如果您对W3的舍入示例感兴趣，并且具有更多的样式和移动部分。我正在为此进行演示，以便今天再次出售订阅。

如果我正确理解了您想要的内容，那么可以使用W3Schools方法的一个细微变化。

为显示正在发生的情况，这是一个原始版本，与原始版本相比变化很小：

.switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
}

.switch input {display:none;}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ccc;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: attr(data-off);
  line-height:26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked + .slider {
  background-color: #2196F3;
}

input:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slider:before {
  content: attr(data-on);
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}

<label class="switch">
  <input type="checkbox">
  <span class="slider" data-off="Off" data-on="On"></span>
</label>

还有更多CSS，使其更像您的示例：

.slide-btn-alt {
  position: relative;
  display: inline-block;
  width: 108px;
  height: 34px;
}

.slide-btn-alt input {display:none;}

.slide-btn-content {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #2b99d6;
  text-transform:uppercase;
  -webkit-transition: .3s;
  transition: .3s;
}

.slide-btn-content::before {
  position: absolute;
  content: attr(data-off);
  font: 900 10px/34px 'Montserrat-Bold', sans-serif;
  color: white;
  width: 50%;
  left: 0;
  bottom: 0;
  text-align: center;
  -webkit-transition: .3s;
  transition: .3s;
}

.slide-btn-content::after {
  position: absolute; content: '';
  height: 34px;
  left: 49%;
  bottom: 0;
  border-left: 2px solid rgba(238, 238, 239, 0.2);
}

input:checked + .slide-btn-content {
  background-color: #485679;
}

input:focus + .slide-btn-content {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slide-btn-content::before {
  content: attr(data-on);
  -webkit-transform: translateX(54px);
  -ms-transform: translateX(54px);
  transform: translateX(54px);
}

<label class="slide-btn-alt">
  <input type="checkbox">
  <span class="slide-btn-content" data-off="Off" data-on="On"></span>
</label>

切换按钮使用纯CSS
