它已经看起来很相似，但我注意到几个问题：

>当标签调整大小时，角度变得混乱
> z-indexing不能按预期工作
>悬停事件不起作用
>哪里的标签重叠它看起来不好
>文本不是垂直居中的(在Firefox中它实际上是工作的)
>选项卡底部缺少曲线
> x按钮不贴在右边

有任何想法吗？

我试图查看chromes源代码，看看是否可以找到原始的颜色/透明度/曲线值，但是I couldn’t find anything。

在我忘记之前，如果可能的话，我希望这可能与IE8或多或少兼容，即使这意味着标签不能是梯形形状等。

EDIT2：从零开始重写整个事情。 (对于新的标签按钮，本·莱斯 – 刘易斯的信用)
