如何创建一个与Bootstrap 3配合良好的粘性页脚

标签: css twitter-bootstrap twitter-bootstrap-3 sticky-footer

无论有没有顶级导航,网站都有一个粘性页脚是很常见的。 Bootstrap可以轻松创建固定页脚,但没有这样的工具用于创建粘性页脚 - 这有很大的不同。

谷歌搜索这个问题将揭示数百(如果不是数千)开发人员有相同的问题,但没有好的答案。

具有讽刺意味的是,Bootstrap documentation页面本身具有粘性页脚以及引导样式和固定的顶部导航栏。这是所有自定义css,但不是框架的一部分。所以一个明显的路线是采取和重构他们的自定义样式,因为它显然在Bootstrap框架中运行良好,但这似乎比它应该更痛苦。

A non-sticky footer is pretty ugly

所需解决方案:

A sticky footer is always at the bottom

当然,页脚应该具有响应性和跨浏览器友好性......

正如Schmalzy所指出的,答案可以在getbootstrap网站的示例部分找到here

但该示例不包括顶级导航。对于带有粘性页脚的固定顶部导航,请参阅this 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;
}

答案 1 :(得分:24)

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

http://timothy-long.com/responsive-sticky-footer/

http://www.visualdecree.co.uk/posts/2013/12/17/responsive-sticky-footers/

答案 2 :(得分:19)

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让它更完美(取决于你的项目),所以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%;}}

我一直在寻找一种简单的方法来使粘性页脚工作。 我刚申请class="navbar-fixed-bottom&#34;它立即起作用 唯一要注意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,你可以得到一个简单的工作示例from here

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的{​​{1}}即可在内容和页脚之间添加空格。

我将详细阐述robodo在上述评论中所说的内容,一个非常快速和美观,更重要的是,响应(非固定高度)方法不涉及任何黑客攻击是使用flexbox。如果您不受浏览器支持,那么它就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;
}

可以在此处检查浏览器支持:http://caniuse.com/#feat=flexbox

不确定到目前为止你尝试了什么,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;
}

由于它位于bootstrap 3中,因此该站点将使用jQuery。所以解决方案也可以是以下内容,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>

不同的看法,希望它有所帮助。

轻松设置

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

到你的.footer

就这样做

答案 9 :(得分:1)

如果您的html具有(粗略)结构:

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

然后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;
}

...页脚高度为80px。 calc计算包装器的高度等于窗口的高度减去页脚高度(80px),超出.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;
}
