CSS3 simple cutting carousel
Realization idea
- First, create a parent container and use two unordered lists to divide the parent container into two columns through flexible layout.
- Store the picture in li by dividing the picture into two columns by giving the left
li {background: url('图片地址') no-repeat; background-size: 200% 100%;}to the rightli{background-position-x: -300（父容器宽度的一半）px;}. - Give the
ul{ransform-style: preserve-3d; }property to turn on the 3D display of the browser. - Put the li on top of each other with the image of the son and the father
ul{position: relative;} li {position: absolute;}. - Set the rotation of li through the transform attribute.
- You can add here
.box:hover>ul { transition: all 5s;transform: rotateX(360deg); }to see the effect. - Finally, add two buttons to allow users to switch pictures by themselves.
- Only use to change the rotation angle of ul when clicked
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';
}
Finally, attach all the code, I hope it will be helpful to you who learn the front-end
