这是模板页代码：
<div class="item_list" id="case_list"> {dede:list pagesize='100'}
<div class="item">
<dl>
<dt><a target="_blank" href="[field:arcurl/]"><img src="[field:litpic/]" alt="[field:title/]" width="280px" height="251px"/></a></dt>
<dd class="case_name"><a target="_blank" href="[field:arcurl/]">[field:title/]</a></dd>
<dd class="case_tag"><a href='[field:typeurl/]'>[field:typename/]</a></dd>
<dd class="case_int"><a target="_blank" href="[field:arcurl/]">[field:description/]......</a></dd>
</dl>
</div>
{/dede:list} </div>
CSS 如果加了高度 215，图片显示五份之一
.item {
width:280px;
background:#fff;
margin:0px 20px 20px 0px;
padding:0px;
border:1px solid #eee;
overflow:hidden;
}
.item_hover {
border:1px solid #4bcdd9;
width:280px;
margin:0px 20px 20px 0px;
padding:0px;
overflow:hidden;
}
.item dl {
padding:0px 0px 0px 0px;
margin:0px;
width:280px;
