css3菜单具有反圆角 [英] css3 menu with inverse rounded corners

问题描述

我设计了一个导航菜单，如下图所示：

I designed a navigation menu which looks like the image here:

我想用css3圆角和box-shadows代码，不使用任何图片。
问题是第一个菜单项左边的圆角和菜单右边的圆角...我称之为反向圆角...

I want to code it with css3 rounded corners and box-shadows, not using any images. Problem is the rounded corner to the left of the first menu-item, and the one to the right of the menu... I call it a "reverse" rounded corner...

它应该改变：hover 上的颜色。

在css只做这个完成？如何？

Is there any way to get this done in css only? And how?

这只是我的第一次尝试，但我认为它看起来非常有前途。

It's just my first attempt, but I think it looks quite promising.
