为什么IE9需要元标记来呈现圆角？ [英] Why does IE9 require a meta tag to render rounded corners?

问题描述

在刚刚发布的IE9中，您需要提供元标记< meta http-equiv =X-UA-Compatiblecontent =IE = 9/& code>允许css border-radius 呈现。

In IE9, which was just released, you need to provide the meta tag <meta http-equiv="X-UA-Compatible" content="IE=9" /> to allow the css border-radius to render.

为什么？

This link: http://blogs.msdn.com/b/ie/archive/2010/06/16/ie-s-compatibility-features-for-site-developers.aspx indicates that the meta tag is not the only way to enable border-radius. Instead, you can change your doctype.

阅读整篇文章以确定是否要使用doctype或元标记。

Read the whole article to determine whether you want to use the doctype or the meta tag, though.
