是否有可能使文本垂直对齐中间在一个未知的div高度与浮动图像。Groupsection2的第一个和第三个div组，图像将向左浮动；和Groupsection2的第二个和第四个组，图像向右浮动：
<div class="groupsection2 clear">
<div class="groupfeature">
<span><img src="testing-images/antec-quality-h230.png" alt="" height="230"/></span>
<div class="feature-content">
<h3>Reliability you can count on Reliability you can count on</h3>
<p>EA-380D Green is backed with AQ3 - Antec Quality 3 year parts and labor warranty, and you get
unlimited access to Antec’s incomparable technical support and customer service</p>

您尚未共享任何CSS代码。您似乎还缺少一个结束语
这里有一个建议，以实现我认为您正在尝试的目标（适用于IE9）：
