Question

我正在关注一个YouTube教程，并且已创建带有复选框的CSS按钮。我想知道选中复选框后如何更改背景。我对选择器不是很满意。我只想使用CSS，而不要使用JavaScript。谢谢

body {
    margin: 0;
    padding: 0;
    background: #f3f3f3;
}

.center {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

input[type="checkbox"] {
    position: relative;
    width: 80px;
    height: 40px;
    -webkit-appearance: none;
    background: #c6c6c6;
    outline: none;
    border-radius:  20px;
    box-shadow: inset 0 0 5px rgba(0, 0, 0, .2);
    transition: .5s;
}

input:checked[type="checkbox"] {
    background: #03a9f4;

}

input[type="checkbox"]:before {
    content: "";
    position: absolute;
    width: 40px;
    height: 40px;
    border-radius: 20px;
    top: 0;
    left: 0;
    background: #fff;
    transform: scale(1.1);
    box-shadow: 0 2px 5px rgba(0, 0, 0, .2);
    transition: .5s;
    
}

input:checked[type="checkbox"]:before{
    left: 40px;
}
