为什么IE9/Firefox显示与其他浏览器不同的字体大小？

bba*_*tos 12 css font-size internet-explorer-9

我正在编写网站的CSS,并意识到Internet Explorer 9显示的是与其他浏览器(Firefox,Chrome,Safari,IE7和IE8)相比不同的字体大小.

我尝试使用一些RESETS,我指定了字体px,但IE9仍然显示字体大小的差异.

我已经尝试使用font-size中pt,in,百分比,但没有成功.

之前我改变了字体(Georgia,Times New Roman,Verdana).其中一些显示较大,另一些在IE9中较小.

我在IE中检查了缩放设置和文本大小.它们分别为100%和中等.

为了说明,我创建了一个简单的HTML和CSS,您可以看到下面的代码.如何解决这个问题呢？谢谢!
