我正在尝试将标头中的内容从移动设备中的两列移到一列。除IE 7.5移动版外，它在任何地方都可以正清楚地显示：块没有做它应该做的事情。
如何让IE 7.5响应性地工作？

Chromebooks are quickly gaining popularity in schools because of their web capabilities and cost effective price points. However, there are some issues associated with a Chromebook rollout. For example, if you have legacy Windows applications, you are forced to either abandon them or use different hardware to gain access to them. Additionally, Chromebooks do not support Java based web applications, limiting their effectiveness as an educational tool.
<br /><br />
There is also the issue of integrating Chromebooks into your existing infrastructure. How do you manage them easily with all the other machines you are managing?
<br /><br />
Stoneware products are a cost effective way to integrate Chromebooks into your existing IT environment. Our products webRDP and <a style="color:#00689c;" href="http://www.stone-ware.com/webnetwork" target="_blank">webNetwork</a> give you the ability to access legacy Windows applications, Java based web applications, as well as HTML5 web apps. <br /><br />

如果你将浮动应用于表格单元格，那么你就会破坏它。它应该使它流入一列。
td[class=items] {
width:94% !important;
display:block;
float:left;
clear:both;
padding-top:10px;
}
