CSS

* {     box-sizing: border-box; }  body {     display: flex;     align-items: center;     justify-content: center;     height: 100vh;     overflow: hidden;     margin: 0; }  .container {     display: flex;     width: 90vw; }  .panel {     background-size: cover;     background-position: center;     background-repeat: no-repeat;     height: 80vh;     border-radius: 50px;     color: #fff;     cursor:  pointer;     /* 增长系数,这样会使图片有竖条感觉 */     flex: 0.5;     margin: 10px;     position: relative;     /* 过渡方式,好多动画用到这个,看来着重要学一下,不过这个all好像去掉不影响大局? */     transition: all 700ms ease-in;     /* 时间影响展示时间,感觉调节时间匹配更好 */ }  .panel h3 {     font-size: 24px;     position: absolute;     /* 定义说明文字位置 */     bottom: 20px;     left: 20px;     margin: 0;     /* 文字透明度 */     opacity: 0; }  .active {     /* 这个MDN上说是增长系数,就是比值可以这样说吧,按我来讲 */     flex: 5; }  .active h3 {     /* 如果有active属性,就将说明文字显现 */     opacity: 1;     transition: opacity 0.3s ease-in 0.4s; }  @media (max-width: 480px) {     /* 一般而言这种都是电脑展示吧,所以很鸡肋?当然依然不可或缺,可以不用,但不能没有 */     .container {         width: 100vh;     } } /* 下面这个真的不知道为什么有啊 */ /* .panel:nth-of-type(4), .panel:nth-of-type(5) {     display: none; } */   

JS

const panels = document.querySelectorAll('.panel'); // 找到pnael标签,这应该是列; // console.log(panels);   // 遍历所有的元素,查看谁被点击了,找到之后将其他元素的active全部清除,并为当前属性添加active panels.forEach(function(panel) { //遍历 panels 序列     panel.addEventListener('click', function(){         removeActiveClasses(); //移除 active标签         panel.classList.add('active');     }); });  function removeActiveClasses () {     panels.forEach(function (panel) {         panel.classList.remove('active');     }) }

CSS

* {     box-sizing: border-box; }   body {      /* 背景图片为渐变色 */     background-image: linear-gradient(90deg,#7d5fff,#7158e2);     /* flex布局 */     display: flex;     /* 竖直居中 */     align-items: center;     /* 水平居中 */     justify-content: center;     /* 非常奇怪啊,有100vh可以居中,100%不成 */     height: 100vh;     overflow: hidden;     margin: 0; }    .search {     position: relative;     height: 50px; }  .search .input {     background-color: #fff;     border: 0;     font-size: 18px;     padding: 15px;     height: 50px;     width: 50px;     /* 转变属性width */     transition : width 0.3s ease;  }  .btn {     background-color: #fff;     border: 0;     cursor: pointer;     font-size: 24px;     position: absolute;     top: 0;     left: 0;     height: 50px;     width: 50px;     /* 平滑移动 */     transition : transform 0.3s ease; } .btn:focus, .input:focus {     outline: none }  .active .input {     width: 200px;   }  .active .btn {     /* 向X轴偏移198px */     transform: translateX(198px);   }    

JS

let search = document.querySelector('.search'); let btn = document.querySelector('.btn'); let input = document.querySelector('.input');  // 添加监听函数 btn.addEventListener('click',function(e) {     // 如果active已经存在,则移除它,否则添加属性     search.classList.toggle('active');     // 效果:<div class="search active"></div>     console.log(search);     // input.focus(); });
