CSS3动画之无缝滚动

CSS3动画之⽆缝滚动
与js的⽆缝滚动类似，整个承载图⽚的盒⼦移动，克隆⼀组图⽚放置最后，当⼀组图⽚播放结束后将盒⼦定位在有⼀组图⽚宽度的左侧HTML结构：
<div class="box">
<ul class="left">
<li><img src="../image/wufenggundong/1.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/2.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/3.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/4.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/5.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/6.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/7.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/8.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/1.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/2.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/3.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/4.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/5.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/6.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/7.jpg" alt=""/></li>
<li><img src="../image/wufenggundong/8.jpg" alt=""/></li>
</ul>
</div>
