我想實現一個基於CSS的切換/開關輸入。我發現以下鏈接的例子非常簡單,根本不使用JavaScript。問題是,它缺乏的是如何確定「切換」狀態如何確定CSS切換輸入的「切換」狀態?

這是供參考的完整代碼的解釋:
/* The switch - the box around the slider */
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
/* Hide default HTML checkbox */
.switch input {display:none;}
/* The slider */
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
-webkit-transition: .4s;
transition: .4s;
border-radius: 34px;
}
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
-webkit-transition: .4s;
transition: .4s;
border-radius: 50%;
}
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);
}
<!-- Rounded switch -->
<label class="switch">
<input type="checkbox">
<div class="slider"></div>
</label>
