<!-- .ipt { display: none; } .box { width: 74px; height: 30px; line-height: 30px; overflow: hidden; border: 1px solid #eee; border-radius: 4px; position: relative; cursor: pointer; } label {display:inline-block;} .ipt:checked .box .switch-btn { left: 0; } .switch-btn { position: absolute; left: -37px; top: 0; width: 111px; height: 30px; transition: all 0.5s; } .switch-btn span{ width: 37px; height: 30px; display: block; text-align: center; float: left; font-size: 14px; } .on { background: #52B13C; color: white; } .white { background: white; } .off { background: #EEEEEE; } -->

主要使用label input来实现改变left的值,下面是核心代码,意思就是选中的input的兄弟节点.box下的.switch-btn元素的left会变成0px(原来是-37px);

代码语言:javascript复制
        .ipt:checked   .box .switch-btn {
            left: 0;
        }

当然要配合transition来实现

下面是效果

ON OFF

全部css代码

代码语言:javascript复制
            .ipt {
                display: none;
            }
            .box {
                width: 74px;
                height: 30px;
                line-height: 30px;
                overflow: hidden;
                border: 1px solid #eee;
                border-radius: 4px;
                position: relative;
                cursor: pointer;
            }
            .ipt:checked   .box .switch-btn {
                left: 0;
            }
            .switch-btn {
                position: absolute;
                left: -37px;
                top: 0;
                width: 111px;
                height: 30px;
                transition: all 0.5s;
            }
            .switch-btn span{
                width: 37px;
                height: 30px;
                display: block;
                text-align: center;            
                float: left;
                font-size: 14px;
            }
            .on {
                background: #52B13C;
                color: white;
            }
            .white {
                background: white;
            }
            .off {
                background: #EEEEEE;
            }
