使用这段代码在引导它的工作

<div class="navbar fixed-bottom">
<div class="container">
 <p class="muted credit">Footer <a href="http://google.com">Link</a> and <a 
href="http://google.com/">link</a>.</p>
 </div>
 </div>

使用Bootstrap 3.6.6测试。

HTML

<div class="container footer navbar-fixed-bottom">
  <footer>
    <!-- your footer content here -->
  </footer>
</div>

CSS

.footer {
  bottom: 0;
  position: absolute;
}

HTML

<div id="wrapper">

  <div id="content">
    <!-- navbar and containers here -->
  </div>

  <div id="footer">
   <!-- your footer here -->
  </div>

</div>

CSS

html, body {
  height: 100%;
}

#wrapper {
  min-height: 100%;
  position: relative;
}

#content {
  padding-bottom: 100px; /* Height of the footer element */
}

#footer {
  width: 100%;
  height: 100px; /* Adjust to the footer needs */
  position: absolute;
  bottom: 0;
  left: 0;
}

对于Sticky Footer，我们在HTML中使用了两个DIV来实现基本的Sticky Footer效果。这样写:

HTML

<div class="container"></div>

<div class="footer"></div>

CSS

body,html {
    height:100%;
}
.container {
    min-height:100%;
}
.footer {
    height:40px;
    margin-top:-40px;
}

发现这里的片段工作得很好

Html:

<div id="wrap">
  <div id="main" class="container clear-top">
    <p>Your content here</p>
  </div>
</div>
<footer class="footer"></footer>

CSS:

html, body {
  height: 100%;
}

#wrap {
  min-height: 100%;
}

#main {
  overflow:auto;
  padding-bottom:150px; /* this needs to be bigger than footer height*/
}

.footer {
  position: relative;
  margin-top: -150px; /* negative value of footer height */
  height: 150px;
  clear:both;
  padding-top:20px;
} 

要处理宽度限制布局，请使用以下方法，这样您就不会得到圆角，并且您的导航条将与应用程序的两侧齐平

<div class="navbar navbar-fixed-bottom">
    <div class="navbar-inner">
        <div class="width-constraint clearfix">
            <p class="pull-left muted credit">YourApp v1.0.0</p>

            <p class="pull-right muted credit">©2013 • CONFIDENTIAL ALL RIGHTS RESERVED</p>
        </div>
    </div>
</div>

然后可以使用CSS重写引导类来调整高度、字体和颜色

    .navbar-fixed-bottom {
      font-size: 12px;
      line-height: 18px;
    }
    .navbar-fixed-bottom .navbar-inner {
        min-height: 22px;
    }
    .navbar-fixed-bottom .p {
        margin: 2px 0 2px;
    }
