我最近开始使用Twitter Bootstrap并且发现它非常直观，除了一件事。
我目前正在构建一个网站，其中包含一个包含图像的包装器（类.sliderwrap），最终将替换为图像滑块。图像/滑块覆盖了h1文本，该文本位于绝对位置。
在较小的屏幕宽度上，我的导航菜单变为下拉列表。当下拉列表打开时，它会在.sliderwrap内向下按下图像，但会重叠.sliderwrap本身和绝对定位的文本，而不是将其向下推。这显然会破坏h1文本，我希望将其与图像一起沿着页面传播。
如何让下拉按下.sliderwrap本身而不是重叠一些呢？
Here's the page I'm having the issue with.（请原谅下拉本身的样式，它还远未完成！）

我认为最简单的解决方案是您需要在主菜单和辅助菜单中清除浮动。
如你所见，你有：
<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。我还建议您养成在代码中添加行的习惯，这样就可以清楚地了解这些内容。
您的代码应该看起来像这样：
<div class="row">
<div class="navbar navbar-static-top">...</div>
<div class="secondmenu">...</div>
</div>
最后但并非最不重要的......您的文字与滑块div完全无关，而是与浏览器镶边相关，因此您需要使滑块容器具有position: relative，因此任何元素都设置为该容器内的position: absolute（在这种情况下，您的h1）将完全根据其父容器定位。
所以在你的风格中设置它：
.sliderwrap {
position: relative;
}
这几乎修复了你的双重菜单，因此它清除了滑块和文本。让我知道这是否适合您，如果您需要澄清答案，请不要忘记投票或接受答案，如果它有效！欢呼声。
