应一个朋友要求替他把原本静态页面做成翻牌的特效。
主要应用了CSS3的transform，transiton。首先写好标签，一个ul下两个li元素，通过position的absolue设置两个li元素重合，设置z-index大小使不同呈现。然后css中设置hover事件并更改相应CSS属性。代码如下
<!DOCTYPE html>
<html lang="en"> <head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
* {
margin: 0;
padding: 0;
} ul,
li {
margin: 0;
padding: 0;
list-style: none;
} .nav {
transition: transform 0.6s ease-out;
transition: transform .5s ease-in-out;
-webkit-transition: transform .5s ease-in-out;
-moz-transition: transform .5s ease-in-out;
-ms-transition: transform .5s ease-in-out;
-o-transition: transform .5s ease-in-out;
-webkit-transform-style: preserve-3d;
/*使其子类变换后得以保留 3d转换后的位置*/
-moz-transform-style: preserve-3d;
-ms-transform-style: preserve-3d;
-o-transform-style: preserve-3d;
transform-style: preserve-3d;
display: block;
position: relative;
} .nav:hover .list2 {
transform: rotateY(0deg);
-webkit-transform: rotateY(0deg);
z-index: 2;
} .nav:hover .list1 {
transform: rotateY(180deg);
-webkit-transform: rotateY(180deg);
z-index: 1;
} .nav,
.list1,
.list2 {
width: 200px;
height: 200px;
}
.list1,
.list2{
backface-visibility: hidden;
transition: 0.6s ease-out;
-webkit-transition: .6s ease-out;
-webkit-transform-style: preserve-3d;
-moz-transform-style: preserve-3d;
-ms-transform-style: preserve-3d;
-o-transform-style: preserve-3d;
transform-style: preserve-3d;
position: absolute;
top: 0;
left: 0;
}
.list1 {
z-index: 2;
transform: rotateY(0deg);
transform: rotateY(0deg);
-webkit-transform: rotateY(0deg);
-moz-transform: rotateY(0deg);
-ms-transform: rotateY(0deg);
-o-transform: rotateY(0deg);
} .list2 {
z-index: 1;
transform: rotateY(-180deg);
transform: rotateY(-180deg);
-webkit-transform: rotateY(-180deg);
-moz-transform: rotateY(-180deg);
-ms-transform: rotateY(-180deg);
-o-transform: rotateY(-180deg);
}
</style>
