如何創建切換開關

第一步 - 添加 HTML:

<!-- 矩形開關 -->
<label class="switch">
  <input type="checkbox">
  <span class="slider"></span>
</label>
<!-- 圓角開關 -->
<label class="switch">
  <input type="checkbox">
  <span class="slider round"></span>
</label>

第二步 - 添加 CSS:

/* 開關 - 滑塊周圍的框 */
.switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
}
/* 隱藏默認 HTML 復選框 */
.switch input {
  opacity: 0;
  width: 0;
  height: 0;
}
/* 滑塊 */
.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: "";
  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 {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}
/* 圓角滑塊 */
.slider.round {
  border-radius: 34px;
}
.slider.round:before {
  border-radius: 50%;
}
