效果如下:拖动翻阅卡片,或点击‘下一张’翻阅卡片效果
思路:
使用过渡样式transform和transition配合来控制卡片向前推进的过渡效果(注:透明度样式要设置在卡片的内容元素上),
然后用js的监听触摸事件来实现拖动f效果
示例代码:
CSS:
.containt{position:absolute; top:0; bottom:0; left:0; right:0; overflow:hidden;} ul,li{margin:0; padding:0;} ul{position:absolute; left:100px; right:100px; top:150px; bottom:200px;} ul>li{list-style:none; display:none; position:absolute; top:0; left:0; width:100%; height:100%; border-radius: 15px; overflow:hidden; box-shadow:0 20px 40px rgba(0,0,0,0.1); background:#f6f6f6; transition:.3s; -webkit-transition:.3s; cursor:pointer;} ul>li img{width:100%;} ul>li:nth-child(1){display: block; z-index:2;} ul>li:nth-child(2){display: block; transform:matrix(0.95,0,0,1,0,-20); -webkit-transform:matrix(0.95,0,0,1,0,-20); z-index: 1;} ul>li:nth-child(3){display: block; transform:matrix(0.9,0,0,1,0,-40); -webkit-transform:matrix(0.9,0,0,1,0,-40); z-index: 0;} ul>li>.content{height:100%; width: 100%;} ul>li:nth-child(2)>.content{opacity:0.9;} ul>li:nth-child(3)>.content{opacity:0.8;} .footer{position: absolute; display:flex; display:-webkit-flex; bottom:0; left:0; right:0; height:150px; -webkit-align-items:center; -webkit-justify-content:center; text-align: center;} .footer .button{width:80px; height:80px; line-height: 80px; background:#000; border-radius: 50%; color:#fff;}
