左右控制器 为什么不在图片内部显示
<div id="slidershow" class="carousel">
<ol class="carousel-indicators">
<li class="active">1</li>
<li>2</li>
<li>3</li>
</ol>
<!-- 设置轮播图片 -->
<div class="carousel-inner">
<div class="item active">
<a href="##"><img src="http://images3.c-ctrip.com/rk/201407/ll580x145.jpg" alt=""></a>
<div class="carousel-caption">
<h3>图片标题1</h3>
<p>描述内容1...</p>
</div>
</div>
<div class="item">
<a href="##"><img src="http://images3.c-ctrip.com/dj/201408/zj/zj_580145.jpg" alt=""></a>
<div class="carousel-caption">
<h3>图片标题2</h3>
<p>描述内容2...</p>
</div>
</div>
<div class="item">
<a href="##"><img src="http://images3.c-ctrip.com/dj/201408/zqgq_580145.jpg" alt=""></a>
<div class="carousel-caption">
<h3>图片标题3</h3>
<p>描述内容3...</p>
</div>
</div>
</div>
<a calss="left carousel-control" href="">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
</div>
这样写有什么问题吗 是放在carousel容器里了啊
