JS部分 setzIdx 函数有修正，CSS加入控制图片尺寸的代码，HTML图片代码全部使用原生img标签：

<style>
.book {
left: -180px;
display: flex;
align-items: center;
width: 1000px;
height: 620px;
perspective: 1000px;
cursor: pointer;
padding: 10px;
position: relative;
background: rgba(0,0,0,.0);
}
.page {
background: #FFFFFF;
padding: 0px;
width: 410px;
height: 600px;
left: 50%;
border-left: 1px solid #DCDCDC;
transform-origin: left;
box-shadow: inset 0px 0px 2px rgba(0,0,0,.5), 1px 1px 12px rgba(255,255,255,.8);
transform-style: preserve-3d;
position: absolute;
}
.page div:nth-child(1) { }
.page div:nth-child(2) { display: none; }
.page img { width: 100%; height: 100%; }
@keyframes rot1{
from { transform: rotateY(0deg); }
to { transform: rotateY(-180deg); }
}
@keyframes rot2{
from { transform: rotateY(-180deg); }
to { transform: rotateY(0deg); }
}
</style>
