如何在页面滚动时始终保持页眉静止？
问题描述：
我该如何去保持我的header不会滚动页面的其余部分？我想过利用frame-sets和iframes，只是想知道是否有一种更简单和更友好的方式，这样做的最佳做法是什么？如何在页面滚动时始终保持页眉静止？

使用position: fixed包含您的头，喜欢的东西
#header {
position: fixed;
}
#content {
margin-top: 100px;
}
在这个例子中div，当#content开始关闭100像素以下#header，但是当用户滚动，#header停留在地方。当然，不言而喻，您需要确保#header具有背景，以便在两个div重叠时其内容实际上可见。看一看在position物业位置：http://reference.sitepoint.com/css/position

取决于你的'div's之间的关系，你可能需要在'＃header'中添加'margin-top：-100px;'来获得它回到你想要的地方。 – rymo 2012-02-29 18:52:20

你知道一种方式让它滚动，直到它达到顶部，然后“位置：固定;”？如果你的头部低于顶部？ – 2013-04-18 19:21:16

这里是一个用CSS + jQuery的（JavaScript）的解决方案。
这里是演示链接Demo
//html
<div id="uberbar">
<a href="#top">Top of Page</a>
<a href="#bottom">Bottom of Page</a>
</div>
//css
#uberbar {
border-bottom:1px solid #eb7429;
background:#fc9453;
padding:10px 20px;
position:fixed;
top:0;
left:0;
z-index:2000;
width:100%;
}
//jquery
$(document).ready(function() {
(function() {
//settings
var fadeSpeed = 200, fadeTo = 0.5, topDistance = 30;
var topbarME = function() { $('#uberbar').fadeTo(fadeSpeed,1); }, topbarML = function() { $('#uberbar').fadeTo(fadeSpeed,fadeTo); };
var inside = false;
//do
$(window).scroll(function() {
position = $(window).scrollTop();
if(position > topDistance && !inside) {
//add events
topbarML();
$('#uberbar').bind('mouseenter',topbarME);
$('#uberbar').bind('mouseleave',topbarML);
inside = true;
}
else if (position < topDistance){
topbarME();
$('#uberbar').unbind('mouseenter',topbarME);
$('#uberbar').unbind('mouseleave',topbarML);
inside = false;
}
});
})();
});

我perso最后需要一张桌面，左边和顶部的标题始终可见。受到几篇文章的启发，我认为我有一个很好的解决方案，可能会对您有所帮助。 此版本没有其他soltion与浮动div或灵活/自动调整列和行大小的包装问题。

如果你可以使用bootstrap3那么你可以使用CSS“导航栏固定顶” 还需要添加下面的CSS把你的网页内容下推
body{
margin-top:100px;
}
答
而是与定位工作和填充/边距，而不知道标题的大小，有一种方法可以通过播放滚动来保持标题的固定。
见this plunker具有固定头：
<html lang="en" style="height: 100%">
<body style="height: 100%">
<div style="height: 100%; overflow: hidden">
<div>Header</div>
<div style="height: 100%; overflow: scroll">Content - very long Content...
这里的关键是height: 100%与overflow组合。

一个有问题的解决方案。看起来内容的底部被推到了窗口的下方。如果您将标题设置得更高，您可以更清楚地看到它。任何想法如何解决这个问题？ – 2015-10-12 13:49:43

通过所有的答案寻找后，我发现用最小的CSS，没有JS的方式略有不同，需要在#content正确设置，在这种情况下60px
CSS只有标题的高度：
#header {
position: fixed;
width: 100%;
top: 0;
z-index: 10;
}
#content {
margin-top: 60px;
z-index:1;
}
HTML：
<body>
<div id="header" style="background-color:GRAY; text-align:center; border-bottom:1px SOLID BLACK; color:WHITE; line-height:50px; font-size:40px">
My Large Static Header
</div>
<div id="content">
<!-- All page content here -->
</div>
</body>
你说的'header'是什么意思？一个页面？桌子上？ – BrunoLM 2010-08-29 05:28:21
