内容和页脚之间的额外空间

标签： css html spacing

我使用my site在this method设置了粘性页脚，由于某种原因，内容底部和页脚顶部之间存在大量额外空间。我无法弄清楚为什么。由于第一页上的内容不多，因此页面甚至不应超出视口范围，也不应该有滚动条。发生了什么事？

以下是该页面的代码：

<!DOCTYPE html>
<html>
  <head>
    <meta charset='utf-8'>
    <meta http-equiv="X-UA-Compatible" content="chrome=1">

    <link rel="stylesheet" type="text/css" href="/css/styles.css" media="screen" />
    <link rel="stylesheet" type="text/css" href="/css/pygment_trac.css" media="screen" />
    <link href="/menu_assets/styles.css" rel="stylesheet" type="text/css">

    <title>gulshansingh.com</title>
  </head>

  <body>
    <header>
      <img src="/images/banner.jpg">
    </header>
    <div id='cssmenu'>
      <ul>
    <li><a href='/'><span>Home</span></a></li>
    <li><a href='/about/'><span>About</span></a></li>
    <li><a href='/projects/'><span>Projects</span></a></li>
    <li><a href='/articles/'><span>Articles</span></a></li>
      </ul>
    </div>

    <div class="container">
      <section id="main_content">
    <h3>Welcome to GitHub Pages.</h3>

<p>This is a test home page for my site</p>

<pre><code>$ cd your_repo_root/repo_name
$ git fetch origin
$ git checkout gh-pages
</code></pre>

<h3>Section 2</h3>

<p>Lorem ipsum</p>

      </section>
      <div class="push">
    </div>
    </div>

    <div id="footer">
      Footer content goes here
    </div>

  </body>
</html>

这是CSS（尽管查看Firebug / CDT可能会更有帮助）：

* {
    margin: 0;
}

html, body {
    height: 100%;
    min-height: 100%;
}

.container {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    margin: 0 auto -80px; /* the bottom margin is the negative value of the footer's height */
}

#footer, .push {
    height: 80px; /* .push must be the same height as .footer */
}

.container元素应该包围除页脚之外的所有其他元素。这意味着你必须将标题放在.container元素中，因为它的高度为100％意味着它将占用视口的高度。由于您的标题/导航已从.container元素中排除，因此视口高度将进一步向下延伸到标题的高度。

请考虑将您的示例发布在一个小提琴而不是您的网站，或任何其他外部网站，使其过于本地化，与SO社区的其他成员不太相关。
