在这里，你会发现HAML (http://haml.info)的方法，导航栏在顶部，页脚在页面底部:

%body
  #main{:role => "main"}
    %header.navbar.navbar-fixed-top
      %nav.navbar-inner
        .container
          /HEADER
      .container
        /BODY
    %footer.navbar.navbar-fixed-bottom
      .container
        .row
          /FOOTER

我找到了mix of navbar-inner和navbar-fixed-bottom

<div id="footer">
 <div class="navbar navbar-inner  navbar-fixed-bottom">
    <p class="muted credit"><center>ver 1.0.1</center></p>
 </div>
</div>

这看起来不错，而且对我很有效

参见小提琴中的例子

你可以使用jQuery来处理这个问题:

$(function() {
    /**
     * Read the size of the window and reposition the footer at the bottom.
     */
    var stickyFooter = function(){
        var pageHeight = $('html').height();
        var windowHeight = $(window).height();
        var footerHeight = $('footer').outerHeight();

        // A footer with 'fixed-bottom' has the CSS attribute "position: absolute",
        // and thus is outside of its container and counted in $('html').height().
        var totalHeight = $('footer').hasClass('fixed-bottom') ?
            pageHeight + footerHeight : pageHeight;

        // If the window is larger than the content, fix the footer at the bottom.
        if (windowHeight >= totalHeight) {
            return $('footer').addClass('fixed-bottom');
        } else {
            // If the page content is larger than the window, the footer must move.
            return $('footer').removeClass('fixed-bottom');
        }
    };

    // Call when this script is first loaded.
    window.onload = stickyFooter;

    // Call again when the window is resized.
    $(window).resize(function() {
        stickyFooter();
    });
});

另一种可能的解决方案是使用媒体查询

@media screen and (min-width:1px) and (max-width:767px) {
    .footer {
    }
}
/* no style for smaller or else it goes weird.*/
@media screen and (min-width:768px) and (max-width:991px) {
    .footer{
        bottom: 0;
        width: 100%;
        position: absolute;
    }
}
@media screen and (min-width:992px) and (max-width:1199px) {
    .footer{
        bottom: 0;
        width: 100%;
        position: absolute;
    }
}
@media screen and (min-width:1120px){
    .footer{
        bottom: 0;
        width: 100%;
        position: absolute;
    }
}

bootstrap是这样做的:

只需使用页面源代码，您就应该能够看到。不要忘记<div id="wrap">在顶部。

更简单的官方示例:http://getbootstrap.com/examples/sticky-footer-navbar/

html {
  position: relative;
  min-height: 100%;
}
body {
  margin-bottom: 60px;
}
.footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 60px;
  background-color: #f5f5f5;
}
