應一個朋友要求替他把原本靜態頁面做成翻牌的特效。
主要應用了CSS3的transform，transiton。首先寫好標簽，一個ul下兩個li元素，通過position的absolue設置兩個li元素重合，設置z-index大小使不同呈現。然後css中設置hover事件並更改相應CSS屬性。代碼如下
<!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;
/*使其子類變換後得以保留 3d轉換後的位置*/
-moz-transform-style: preserve-3d;
-ms-transform-style: preserve-3d;
-o-transform-style: preserve-3d;
transform-style: preserve-3d;

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 {

}
