了解如何使用 CSS 创建拨动开关（on/off 按钮）。
如何创建拨动开关
步骤 1) 添加 HTML:
实例
<!-- 矩形开关 -->
<label class="switch">
<input type="checkbox">
<span class="slider"></span>
</label>
<!-- 圆形开关 -->
<label class="switch">
<input type="checkbox">
<span class="slider round"></span>
</label>
步骤 2) 添加 CSS:
实例
/* 开关 - 滑块周围的框 */
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
/* 隐藏默认 HTML 复选框 */
.switch input
{
opacity: 0;
width: 0;
height: 0;
}
/* 滑块 */
.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);
}
/* 圆形滑块 */
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
