【问题描述】:
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。但事实证明它比我想象的要复杂得多。
它看起来已经很相似了,但我注意到了几个问题:
- 调整选项卡大小时,角度会变得混乱
- z 索引未按预期工作
- 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 中它确实有效)
- 标签底部缺少曲线
- x 按钮不靠右
有什么想法吗?
我试图查看 chromes 源代码,看看是否可以找到原始颜色/透明度/曲线值,但 I couldn't find anything。
在我忘记之前,如果可能的话,我希望它或多或少与 IE8 兼容,即使这意味着标签不能是梯形等。
EDIT2:从头开始重写整个内容。 (感谢 Ben Rhys-Lewis 的新标签按钮)

【问题讨论】:
-
这看起来甚至不像 Chrome 的标签栏。
-
看起来不像 Chrome 标签页。至少在 Firefox 中。我已经看过所有这些链接..
