无论有没有顶部导航,网站都有一个粘性页脚是很常见的。Bootstrap 具有轻松创建固定页脚的功能,但没有创建粘性页脚的功能 - 有很大的不同。

谷歌搜索这个问题会发现成百上千的开发人员有同样的问题,但没有好的答案。

具有讽刺意味的是,Bootstrap 文档页面本身在引导样式和固定顶部导航栏旁边有一个粘性页脚。不过,这都是自定义 css,而不是框架的一部分。因此,一条明显的路线是采用并重构他们的自定义样式,因为它显然在 Bootstrap 框架中运行良好,但这似乎比它应该的更痛苦。

有关带有 Bootstrap 顶部导航栏和不受欢迎的非粘性页脚的示例页面,请参阅此 plunkr 。

问题:

(感谢 Softlayer - 提供图形

非粘性页脚非常难看

所需的解决方案:

粘性页脚始终位于底部

当然,页脚也应该是响应式的和跨浏览器友好的......

正如 Schmalzy 所指出的,答案可以在getbootstrap站点的示例部分找到。

但该示例不包括顶部导航。对于带有粘性页脚的固定顶部导航,请参阅plnkr 或下面的代码。

样式 CSS:

/* Styles go here */

/* 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;
  /* Negative indent footer by its height */
  margin: 0 auto -60px;
  /* Pad bottom by footer height */
  padding: 0 0 60px;
}

/* Set the fixed height of the footer here */
#footer {
  height: 60px;
  background-color: #f5f5f5;
}


/* Custom page CSS
-------------------------------------------------- */
/* Not required for template or sticky footer method. */

.container {
  width: auto;
  max-width: 680px;
  padding: 0 15px;
}
.container .credit {
  margin: 20px 0;
}

依赖于固定高度页脚的粘性页脚解决方案在响应式方法(页脚的高度经常在不同的断点处发生变化)已经失宠。我见过的最简单的响应式粘性页脚解决方案涉及display: table在顶级容器上使用,例如:

最好的方法是执行以下操作:
HTML: Sticky Footer
CSS: CSS for Sticky Footer
HTML 代码示例:

<div class="container">
  <div class="page-header">
    <h1>Sticky footer</h1>
  </div>
  <p class="lead">Pin a fixed-height footer to the bottom of the viewport in desktop browsers with this custom HTML and CSS.</p>
  <p>Use <a href="../sticky-footer-navbar">the sticky footer with a fixed navbar</a> if need be, too.</p>
</div>

<footer class="footer">
  <div class="container">
    <p class="text-muted">Place sticky footer content here.</p>
  </div>
</footer>

CSS 代码示例:

    html {
  position: relative;
  min-height: 100%;
}
body {
  /* Margin bottom by footer height */
  margin-bottom: 60px;
}
.footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  /* Set the fixed height of the footer here */
  height: 60px;
  background-color: #f5f5f5;
}

另一个小调整可能会使其更完美(取决于您的项目),因此它不会影响移动视图的页脚。

@media (max-width:768px){ .footer{position:absolute;width:100%;} }
@media (min-width:768px){ .footer{position:absolute;bottom:0;height:60px;width:100%;}}

我一直在寻找一种使粘性页脚起作用的简单方法。我刚刚应用了一个class="navbar-fixed-bottom“,它立即工作唯一要记住的是调整移动设备页脚的设置。干杯!

对于那些正在寻找简单答案的人,您可以从这里获得一个简单的工作示例:

html {
    position: relative;
    min-height: 100%;
}
body {
    margin-bottom: 60px /* Height of the footer */
}
footer {
    position: absolute;
    bottom: 0;
    width: 100%;
    height: 60px /* Example value */
}

只需使用body'smargin-bottom在内容和页脚之间添加空间。

我将详细说明 robodo 在上面的评论中所说的内容,一种非常快速且美观的方法,更重要的是,不涉及任何 hack 的响应式(非固定高度)方法是使用 flexbox。如果您不受浏览器支持的限制,这是一个很好的解决方案。

HTML

<body>
  <div class="site-content">
    Site content
  </div>
  <footer class="footer">
    Footer content
  </footer>
</body>

CSS

html {
  height: 100%;
}
body {
  min-height: 100%;
  display: flex;
  flex-direction: column;
}
.site-content {
  flex: 1;
}

浏览器支持可以在这里查看:http: //caniuse.com/#feat=flexbox

不确定到目前为止您尝试了什么,但它非常简单。只需这样做:http ://plnkr.co/edit/kmEWh7?p=preview

html, body {
  height: 100%;
}

footer {
  position: absolute;
  bottom: 0;
}

由于它在引导程序 3 中,因此该站点将使用 jQuery。所以解决方案也可以如下,而不是尝试使用复杂的 CSS:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
    <link href="css/bootstrap.min.css" rel="stylesheet" />
    <style>
        .my-footer {
            border-radius : 0px;
            margin : 0px; /* pesky margin below .navbar */
            position : absolute;
            width : 100%;
        }
    </style>
</head>
<body>
    <div class="container-fluid">
        <div class="row">
            <!-- Content of any length -->
            asdfasdfasdfasdfs <br />
            asdfasdfasdfasdfs <br />
            asdfasdfasdfasdfs <br />
        </div>
    </div>

    <div class="navbar navbar-inverse my-footer">
        <div class="container-fluid">
            <div class="row">
                <p class="navbar-text">My footer content goes here...</p>
            </div>
        </div>
    </div>

    <script src="js/jquery-1.11.0.min.js"></script>
    <script src="js/bootstrap.min.js"></script>

    <script type="text/javascript">
        $(document).ready(function () {
            var $docH = $(document).height();
            // The document height will grow as the content on the page grows.
            $('.my-footer').css({
                /*
                The default height of .navbar is 50px with a 1px border,
                change this 52 if you change the height of your footer.
                */
                top: ($docH - 52) + 'px'
            });
        });
    </script>
</body>
</html>

换个思路,希望对你有帮助。

亲切的问候。

轻松设置

position:absolute;
bottom:0;
width:100%;

到你的 .footer

去做就对了

如果您的 html 具有(粗略)结构:

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

那么将页脚固定到屏幕底部的最简单的CSS是

html, body {
    height: 100%;
}
.wrapper {
  min-height: calc(100vh - 80px);
}
.footer {
   height: 80px;
}

...页脚的高度为80px。calc计算包装器的高度等于窗口的高度减去页脚的高度(80px).wrapper

对我有用的是添加相对于 html 标签的位置。

html {
  min-height:100%;
  position:relative;
}
body {
  margin-bottom:60px;
}
footer {
  position:absolute;
  bottom:0;
  height:60px;
}
