css3代碼部分

<style>
     *{
         padding: 0;
         margin: 0;
     }
     .box{
         display: block;
         width: 300px;
         height: 70px;
     }
     ul{
        display: block;
         width: 300px;
         height: 70px;
         overflow: hidden;
     }
     li{
         display: none;
         width: 300px;
         height: 70px;
     }
     li img{
         display: block;
         width: 300px;
         height: 70px;
     }
     input{
         display: none;
     }
     #button-1:checked~ul li:nth-child(1),
     #button-2:checked~ul li:nth-child(2),
     #button-3:checked~ul li:nth-child(3){
         display: block;
     }

     label{
         position: relative;
         top: -20px;
         left: 50px;
         display: inline-block;
         width:20px;
         height: 20px;
         background: red;
         cursor: pointer;
     }
    </style>
           

html代碼部分

<div class="box">
        <input type="radio" name="button" id="button-1" checked="checked">
        <input type="radio" name="button" id="button-3">
        <input type="radio" name="button" id="button-2">

        <ul>
            <li><img src="mc.png" alt=""></li>
            <li><img src="lb.jpg" alt=""></li>
            <li><img src="zgl.jpg" alt=""></li>

        </ul>
        <label for="button-1">1</label>
        <label for="button-2">2</label>
        <label for="button-3">3</label>
    </div>
           

效果：

說明：點選1，2，3即可切換相應圖檔

設計原理通過點選1，2，3來控制 li 的顯示與否，進而達到效果
