显然我一定是错过了什么。
我试图让标头中的内容在移动设备中从两列变为一列。除了 IE 7.5 mobile，它在任何地方都可以正常工作。显然 display:block 没有做它应该做的事情。
如何让 IE 7.5 响应式地工作？

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 />
