我最近开始使用Twitter Bootstrap，发现它非常直观，除了一件事。
我目前正在构建一个站点，该站点具有一个包含图像的包装器（类.sliderwrap），该包装器最终将被图像滑块所取代。图像/滑块覆盖了绝对定位的h1文本。
在较小的屏幕宽度上，我的导航菜单会变成下拉菜单。当下拉列表打开时，它向下推.sliderwrap中的图像，但与.sliderwrap本身和绝对定位的文本重叠，而不是向下推。这显然破坏了h1文本，我想将其与图像一起沿着页面向下移动。
如何使下拉列表将.sliderwrap本身向下推，而不是重叠其中的一些？
这是我遇到问题的页面。（请原谅下拉列表本身的样式，它还远远没有完成！）
我认为最简单的解决方案是需要清除主菜单和辅助菜单中的浮动。
正如你所看到的：
<div class="navbar navbar-static-top">...</div>
你也有：
<div class="secondmenu">...</div>
清除这些内容的最简单方法是将它们放在.row类或.row-fluid中。我还建议您养成在可能的情况下向代码中添加行的习惯，以使这些事情变得清晰。
你的代码最终应该是这样的：
<div class="row">
<div class="navbar navbar-static-top">...</div>
<div class="secondmenu">...</div>
</div>
最后但同样重要的是。。。您的文本不是绝对相对于滑块div定位的，而是相对于浏览器chrome定位的，因此您需要使滑块容器具有position: relative，以便该容器内设置为position: absolute的任何元素（在本例中为h1）都将完全根据其父容器定位。
所以在你的风格中也设置这个：
.sliderwrap {
position: relative;
}
这几乎修复了你的双菜单，所以它可以清除滑块和文本。如果这对你有效，如果你需要澄清答案，请告诉我，如果有效，别忘了投赞成票或接受答案！干杯
尝试这个
