我正在学Bootstrap.在"入门"菜单上，提供的模板很少.我在玩这个.一个例子是关于固定页脚.我使用了上一个例子中的nav，并希望用固定的页脚来调整它.但是垂直滚动条就要来了.I am looking for element which is causing Vertical Scroll Bar.
以下是HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Bootstrap, from Twitter</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="description" content="">
<meta name="author" content="">
<!-- Le styles -->
<link href="css/bootstrap.css" rel="stylesheet">
<style type="text/css">
/* Sticky footer styles
-------------------------------------------------- */
html,
body {
height: 100%;
/* The html and body elements cannot have any padding or margin. */
}
/* Wrapper for page content to push down footer */
#wrap {
min-height: 100%;
height: auto !important;
height: 100%;
/* Negative indent footer by it's height */
margin: 0 auto -60px;
}
/* Set the fixed height of the footer here */
#push,
#footer {
height: 60px;
}
#footer {
background-color: #f5f5f5;
}
/* Lastly, apply responsive CSS fixes as necessary */
@media (max-width: 767px) {
#footer {
margin-left: -20px;
margin-right: -20px;
padding-left: 20px;
padding-right: 20px;
}
}
/* Custom page CSS

/* Not required for template or sticky footer method. */
.container {

max-width: 680px;

/* Adjust Nav */
#wrap > .container {

我之前遇到过类似的问题，我不记得我是否能找到简单的解决办法.
