我在这个网站上使用navbar-fixed-top（twitter bootstrap）。我想知道有一种方法可以让导航栏的底部像浏览器的顶部一样。
看问题是我不喜欢锚点改变的时间（来回活动）。我的导航栏与我的身体重叠，我不希望这种情况发生在网页的任何地方......永远！
正如你所看到的，我已经尝试在身体上添加填充物，但它只是将身体向下推50 px。有谁知道解决这个问题？我不介意混淆Jquery

上查看我对pol做的评论：
“...当div到达导航栏的底部（而不是浏览器的顶部）时，我希望导航栏的底部像浏览器的顶部一样，然后导航栏中的锚点会发生变化活跃。“

<h1>The James Baldwin School</h1>
<h2>A School For Expeditionary Learning.</h2>
<p>It is our mission to provide a philosophical and practical education for all students, an education that features creativity and inquiry, encourages habitual reading and productivity, as well as self-reflection and original thought. We agree with Socrates that the “unexamined life is not worth living,” and it is our desire to prepare students to live thoughtful and meaningful lives. We are committed to inspiring the love of learning in our students.</p>
<p>It is our mission, as well, at the James Baldwin School, to provide a haven for students who have previously experienced school as unresponsive to their needs as individuals. We wish for all students to find their voice and to speak knowledgeably and thoughtfully on issues that concern their school, their world. We aid students in this endeavor by personalizing our learning situations, by democratizing and humanizing the school environment, and by creating a “talking culture,” an atmosphere of informal intellectual discourse among students and faculty.</p>
<p>Democratizing the school would be impossible without our Core Values. Our core values help students aquire the important skills needed to continue their journey through life. Most importantly, our core values maintain safety and democracy for students and faculty.</p>

在包含像
这样的图像的标签中添加一个类<a href="http://en.wikipedia.org/wiki/James_Baldwin" target="_blank" class="banner_image"><img src="http://i.huffpost.com/gen/1757925/thumbs/o-JAMES-BALDWIN-facebook.jpg" style="width:100%"></a>
现在将此css规则添加到您的css：
a.banner_image{
display:block;
margin-top:50px; /* adjust the margin, what will be the height of the navbar */
}
