如何创建一个与Bootstrap 3配合良好的粘性页脚

Rob*_*ian 77 css sticky-footer twitter-bootstrap twitter-bootstrap-3

无论有没有顶级导航,站点都有一个粘性页脚是很常见的.Bootstrap有一个可以轻松创建固定页脚的工具,但没有这样的工具来创建粘性页脚 - 这有很大的不同.

谷歌搜索这个问题将揭示数百甚至数千名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文档页面本身具有粘性页脚以及引导程序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.所以一个显而易见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.

请参阅此plunkr以获取带有Bootstrap顶部导航栏的示例页面,以及不受欢迎的非粘性页脚.

问题:

(感谢Softlayer - 用于图形)

一个不粘的页脚非常难看

期望的解决方案:

粘性页脚始终位于底部

当然,页脚应该响应和跨浏览器友好...

答案,因为Schmalzy指出,可以发现这里在getbootstrap网站的示例部分.

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 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中失宠(其中页脚的高度经常在不同的断点处改变).我见过的最简单的响应粘性页脚解决方案涉及display: table在顶级容器上使用,例如:

最好的办法是做到以下几点:
HTML:粘页脚
CSS:CSS的粘页脚
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>

body {
  /* Margin bottom by footer height */
  margin-bottom: 60px;
}
.footer {
  position: absolute;

  /* Set the fixed height of the footer here */

另一个小调整可能会使它更完美(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%;}}

  • 将`position:relative`替换为`position:fixed`,以便在向下滚动时将其保持在底部 (4认同)

我一直在寻找一种简单的方法来使粘性页脚工作.我只是应用了class="navbar-fixed-bottom"它立即工作只记住它是为了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,你可以从这里得到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's' margin-bottom来增加内容和页脚之间的空间.
