请查看 Bootply 或代码段下面的内容,我正在使用Bootstrap 3.1,因为我想在我的网站上使用这个很棒的搜索框。但我遇到了问题,导航栏徽标无法正常工作(它甚至没有徘徊,因此它无法点击)。
注意:品牌徽标在移动版中运行良好,仅在桌面版本中存在问题。因此,如果您在代码段下方运行,请单击“全屏”以查看问题。
我不是一个css家伙,所以你们可以帮我解决这个问题。 感谢

看来你已经投入太多精力了。所以我对你的问题有一个CSS黑客攻击。
将徽标优先于其他元素。
添加强>
.navbar-brand {
position: relative;
z-index: 1;
}
现在,搜索在展开时覆盖/优先考虑徽标
更改强>
.navbar-collapse form[role="search"] {
z-index: 2;
}
