CSS3简易切割轮播图的实现代码

实现思路

  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';
        }

最后附上全部代码,希望对学习前端的你有所帮助
