我在尝试让 Bootstrap 3 页脚导航正确放置在 SharePoint 2013 Intranet 网站上时遇到问题。
这就是我所看到的:http://screencast.com/t/vQFVCBbfE7P
在开发人员工具中，我试图将页脚导航本身的 z-index 向下移动到 0(这部分起作用，即灰色背景没有 float 在弹出 div 上)
我的相关 CSS 是
.footerTagline {
background: #001F5B;
color: white;
padding: 2px 0px;
}
#bs-footer-nav ul li ul li {
margin-left: -40px;
}
.BHIFooterInfo, .BHIFooterInfo div {
z-index:0;
position:inherit !important;
background: rgb(138,141,143);
}
.BHIFooterInfo, #companySites {
padding-top: 10px;
padding-bottom: 20px;
}
#bs-footer-nav li {
color: rgb(241, 180, 52);
padding-right: 35px;
}
#bs-footer-nav li ul li {
color: rgb(241, 180, 52);
padding-right: 0px;
}
#bs-footer-nav, #bs-footer-nav a {
background: rgb(138, 141, 143);
color: #fff;
}
.navbar {
margin-bottom: 0px;
}
.footerSocialImages {
width:23px;
height: 23px;
}
#bhiSocialLinks li, #bhiSocialLinks li a {
padding-left: 0px;
padding-right: 2px;
}

</div><!-- /.navbar-collapse -->
</nav>
</div>
</div>
</div>即使在 z-index:0 上一直使用 !important 直到 a 标签似乎也无济于事。
此问题出现在所有浏览器中。
需要注意的是:
- Div 似乎是由 JavaScript 中的 MS 代码生成的(对于所有 Div Popup 创建)
- 它覆盖了 ul 或 li 或 a 中页脚导航中的任何内容
我意识到我缺少一些简单的东西，但 CSS 不是我的强项。任何帮助都将不胜感激。
谢谢
最佳答案
添加以下代码或给我托管的 url 来检查
nav-footer {
z-index:100 !important;
}
