从浮动div中删除多余的边距和填充

Question

问题：对于下面提到的代码，ie7在具有图像的div的两行之间渲染了额外的垂直填充，我尝试了很多方法来解决..但毫无头绪。 我真的需要你的帮助。 该代码可在符合标准的浏览器中正常运行

HTML代码：

<div id="screensaver_items">
    <div class="header clearfix">
        <div id="header_left">
            <h3>screensavers</h3>
        </div>
        <div id="header_right">

Answer 1

摆脱这个：

#screensaver_items .content:hover .shade{
background-color: #333;
opacity: 0.7;
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=70)";
    filter: alpha(opacity=70); 
opacity: 0.7;
width:  177px;
*width: 177px !important;
height:36px;
position: absolute;
    top: -37px;
*top: -40px !important;
     left: 2px;
*left:2px !important;
display:block;
}

它应该可以正常工作。
