轮播图有着许多实现方式，自己尝试用vue实现轮播图
上代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
*{
margin: 0;
padding: 0;
list-style: none;

}

height: 100%;
}
body{
height: 100%;
display: flex;
justify-content: center;
}
.app{
height: 100%;
width: 100%;
display: flex;
justify-content: center;
}
img{
width: 500px;
height: 300px;
}
li{
width: 500px;
height: 300px;
border: 5px solid white;
color: white;
position: absolute;
}
ul{
width: 510px;
display: flex;
justify-content: center;
align-items: center;
overflow: hidden;
position: relative;
}
.nav{
background-color: #c3c3c3;
color: white;
margin-left: 10px;
font-size: 20px;
border-radius: 50%;
padding: 0 8px;
margin-bottom: 10px;
opacity: 0.5;
}
.active{
opacity: 1;
}
li div{
margin-top: -30px;
}
.image-enter-active {
transition: all 1.5s linear
}
.image-leave-active {
transition: all 1.5s linear;
}
.image-enter-to {
transform: translateX(0);
}
.image-enter {
transform: translateX(100%);
}
.image-leave {
transform: translateX(0);
}
.image-leave-to {
transform: translateX(-100%);
}
</style>
