CSS3簡易切割輪播圖
實作思路
- 首先創建一個父容器，用兩個無序串列通過彈性布局將父容器分為兩欄，
- 在li里面存放圖片通過給左邊的
li {background: url('圖片地址') no-repeat; background-size: 200% 100%;}給右邊的li{background-position-x: -300（父容器寬度的一半）px;}來實作將圖片分割成兩欄， - 給
ul{ransform-style: preserve-3d; }屬性來開啟瀏覽器的3D顯示， - 用子絕父相來將li疊放到一起
ul{position: relative;} li {position: absolute;}， - 通過transform屬性來設定li的旋轉，
- 到這里可以添加
.box:hover>ul { transition: all 5s;transform: rotateX(360deg); }來看看效果， - 最后添加兩個按鈕來讓用戶可以自己切換圖片，
- 點擊時只用改變ul的旋轉角度
btn1.onclick = ()=>{
item++;
let r = item * 90;
letf.style.transform = 'rotateX(' + r + 'deg)';
letf.style.transition = 'all 1s';
right.style.transform = 'rotateX(' + r + 'deg)';
right.style.transition = 'all 1s .3s';
}
btn2.onclick = ()=>{
item--;
let r = item * 90;
letf.style.transform = 'rotateX(' + r + 'deg)';
letf.style.transition = 'all 1s';
right.style.transform = 'rotateX(' + r + 'deg)';
right.style.transition = 'all 1s .3s';
}
最后附上全部代碼，希望對學習前端的你有所幫助
