overflow：hidden不工作

嘿，我有一个艰难的时间与溢出：隐藏。基本上我试图隐藏一个无序列表的溢出位于一个div。我不知道为什么这不工作，虽然。而不是隐藏它，它打破了我的水平布局到垂直布局。无序列表是轮播，容器是列表。我的代码如下：

Hey all, I am having a tough time with overflow: hidden. Basically I am trying to hide the overflow of an unordered list which is located in a div. I have no idea why this isn't working though. Instead of hiding it, it breaks my li's from a horizontal layout to a vertical layout. The unordered list is carousel and the container is list. My code is below:

CSS：

div.body .container .images {
 background: url(/images/images-background.jpg);
 height: 62px;
 margin-bottom: 17px;
 width: 384px;
}
div.body .container .images #images-previous {
 cursor: pointer;
 float: left;
}
div.body .container .images #images-next {
 cursor: pointer;
 float: left;
}
div.body .container .images .list {
 float: left;
 overflow: hidden;
 vertical-align: top;
 width: 336px;
}
div.body .container .images .carousel {
 margin-bottom: 6px;
 margin-top: 8px;
 width: 336px;
}

我的代码：

<div class="images">
 <div id="images-previous"><img src="/images/images-previous.jpg" width="24" height="62" alt="Previous" /></div>
 <div class="list">
  <ul class="carousel">
