Chrome中的样式标签栏？

Question

我正在尝试使用HTML/CSS尽可能准确地重新创建Google Chrome的标签栏.但结果却比我想象的要复杂得多.

它看起来非常相似,但我注意到几个问题:

• 当调整选项卡大小时,角度会变得混乱
• z-indexing无法按预期工作
• 悬停事件不起作用
• 标签重叠的地方看起来很糟糕
• 文本不是垂直居中的(在Firefox中实际上是有效的)
• 标签底部缺少曲线
• x按钮不会粘在右边

有任何想法吗？

我试着查看chromes源代码,看看我是否能找到原始颜色/透明度/曲线值,但我找不到任何东西.

在我忘记之前,如果可能的话,我希望这与IE8或多或少兼容,即使这意味着标签不能是梯形等.

编辑2:从头开始重写整个事情.(Ben-Rhys-Lewis为新标签按钮致记)

好的，这是一个 css 形状的小提琴，就像您想要的新选项卡一样。

#newtab {
    width: 150px;
    height: 100px;
    -webkit-transform: skew(20deg);
       -moz-transform: skew(20deg);
         -o-transform: skew(20deg);
    background: #A8D5C1;
    margin-left: 20px;
    border-radius: 10px;
}

对于透明度值，很难从您的图像中看到，但我想这只是尝试和错误。显然，由于您使用的主题，您的 chrome 的外观与我的外观不同。
