html - 尝试将切换按钮置于页面中央

Question

我试图将切换按钮居中放置在页面的中心，而不更改其任何颜色属性。当我尝试更改其位置时，其颜色会发生变化。我需要帮助将按钮置于页面中央。

Answer 1

可以申请transform属性(property)给<div class="center">使其位于页面中心

.center {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%)
}

body {
  background-color: #7a86cb;
}

.switch {
  position: relative;
  display: inline-block;
  width: 60px;
  height: 34px;
}

/* Hide default HTML checkbox */

.switch input {
  opacity: 0;
  width: 0;
  height: 0;
}

/* The slider */

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: rgba(0, 0, 0, 0.5);
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: rgba(0, 0, 0, 0.5);
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked+.slider {
  background-color: rgba(230, 231, 242, 0.15);
}

input:checked+.slider:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}
/* Rounded sliders */

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

.slider.round:before {
  border-radius: 50%;
}
input:checked+.slider:before {
background-color:#E6E7F2!important
}

<div class="center">
  <label for="toggle"></label>
  <label class="switch">
  <input type="checkbox">
  <span class="slider round"></span>
  </label>
</div>
