将页脚固定在页面底部

Question

尽管我网站上的大多数页面都有足够的内容将页脚推到大多数人的页面底部，但我想知道如何使它始终固定在底部，而不考虑屏幕大小。 我尝试了几种方法，例如使用bottom: 0x;和position:absolute:等，但似乎从未很好地工作过，有时会使用其中一些示例将页脚推出其容器以修复到底部。 包括页脚和版权栏两个部分的HTML和CSS都在<section id="footer"> div中。 我已经删除了自己的粘贴尝试，这样人们就可以现在查看并查看当前代码进行修改。 网址 - http://www.mangdevelopment.co.uk/nakedradish（这是一个餐厅网站，请不要担心“naked”这个词）。HTML

对于您的页脚（footer）：

#footer {
    position: fixed;
    height: 50px;
    background-color: red;
    bottom: 0px;
    left: 0px;
    right: 0px;
    margin-bottom: 0px;
}

关于您的 身体：

body {
    margin-bottom:50px;

刚刚收到这个回答。谢谢，但我不希望它跟随用户而浮动，不要覆盖内容。 - mcvities

无论您的内容高度如何，它都将固定在页脚。由于我已经给body加了margin-bottom，因此您的内容不会被隐藏。 - Girish Thimmegowda

Answer 2

我们可以使用 FlexBox 在 CSS 中不使用位置属性实现固定的 页脚 和 页眉。

.container {
  display: flex;
  flex-direction: column;
  height: 100vh;
}

header {
  height: 50px;
  flex-shrink: 0;
  background-color: #037cf5;
}

footer {
  height: 50px;
  flex-shrink: 0;
  background-color: #134c7d;
}

main {
  flex: 1 0 auto;
}

<div class="container">
  <header>HEADER</header>
  <main class="content">

  </main>
  <footer>FOOTER</footer>
</div>

演示 - JSFiddle

注意：检查浏览器是否支持FlexBox。 caniuse

运行完美！这应该是被接受的答案。 - saran3h

不使用位置的好处是什么？ - ftw

@ftw 没有根据页脚高度设置正文底部边距。 - Assad Nazar

@saran3h 这个问题和被采纳的答案会产生不同的结果。被采纳的答案：页脚始终可见，即使内容大于屏幕尺寸。而这个答案：页脚被推到屏幕/内容的底部，因此如果内容大于屏幕尺寸，则需要滚动才能看到它。所以一切都取决于需求。 - Uriil

完美。只有一个小问题：如果其他人想知道示例中的垂直滚动条来自何方，只需在body元素上设置margin: 0。然后，滚动条仅会在有足够的内容将页脚推出视图时显示出来。 - mwallisch

Answer 3

在选择器 #footer 下添加 position:fixed; 和 bottom:0;：

演示

CSS

#footer {
    background-color: #F3F3F3;
    padding-top: 10px;
    padding-bottom: 0px;
    position:fixed;
    bottom:0;
    width:100%;
}

哦，抱歉，我需要它不覆盖内容。我刚刚添加了您建议的内容，看起来很棒，但是它确实从内容的顶部开始。 - mcvities

@mcvities 我认为固定页脚并不适合您的网站，如果您想要固定，那么顶部面板也需要固定。我认为这样看起来很好。 - Falguni Panchal

@falguni 我认为你在 bottom 中漏掉了 px，所以应该是 bottom:0px 而不是 bottom:0。 - steveb

Answer 4

设置

html, body {
    height: 100%;
}

将页脚前的所有内容都放在一个 div 中。

.wrapper {
    height:auto !important;
    min-height:100%;
}

您可以根据希望在浏览器窗口底部显示页脚的高度自行调整最小高度。如果将其设置为90％，则在滚动前将显示10％的页脚。

Answer 5

CSS

html {
    height:100%;
}
body {
    min-height:100%; position:relative;
}
.footer {
    background-color: rgb(200,200,200);
    height: 115px;
    position:absolute; bottom:0px;
}
.footer-ghost { height:115px; }

HTML

<div class="header">...</div>
<div class="content">...</div>
<div class="footer"></div>
<div class="footer-ghost"></div>

Answer 6

这段代码对我有用:

footer{
    background-color: #333;
    color: #EEE;
    padding: 20px;
    left: 0;
    width: 100%;
    bottom: 0;
    position: fixed;
}

你需要添加的重要事情是 bottom:0; 和 position:fixed;

Answer 7

这里有一个简单的CSS解决方案，可以实现以下效果：

#fix-footer{
    position: fixed;
    left: 0px;
    bottom: 0px;
    height: 35px;
    width: 100%;
    background: #1abc9c;
}

问题是关于将页脚固定在页面底部，position: fixed 将元素固定在视口而不是页面上。 - user776686

Answer 8

在响应式网站上，我发现固定页脚方案有些麻烦，因为导航栏和页脚的高度取决于设备。如果你只关心现代浏览器的工作，你可以使用一些Javascript来实现你的目标。

如果这是你的HTML：

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

然后在每个页面上使用这个JQuery：

$(function(){

  /* Sets the minimum height of the wrapper div to ensure the footer reaches the bottom */
  function setWrapperMinHeight() {
    $('.wrapper').css('minHeight', window.innerHeight - $('.nav').height() - $('.footer').height());
  }
  /* Make sure the main div gets resized on ready */
  setWrapperMinHeight();

  /* Make sure the wrapper div gets resized whenever the screen gets resized */
  window.onresize = function() {
    setWrapperMinHeight();
  }
});

Answer 9

你的页脚元素不会自动固定在视口底部，除非你通过样式实现。
因此，如果你的页面没有足够的内容将其推到底部，它就会出现在视口中间，看起来非常尴尬，不知所措，就像我上高中的第一天一样。

通过声明fixed规则来定位元素很好，如果你希望始终显示页脚，无论初始页面高度如何，但是记得设置底部边距，以免它覆盖该页面上的最后一部分内容。如果你的页脚具有动态高度，则会变得棘手；这通常是响应式网站的情况，因为元素自然堆叠。

使用absolute定位也会遇到类似的问题。虽然它确实将相关元素从文档的自然流程中移出，但如果你发现页面几乎没有内容填充，它仍然无法固定在屏幕底部。 考虑通过以下方式实现：

1. 为 <body> 和 <html> 标签声明高度值
2. 为嵌套的包装器元素声明 minimum-height 值，通常是包装所有身体结构内后代元素的元素（这不包括您的 footer 元素）

Code Pen 示例

$("#addBodyContent").on("click", function() {
  $("<p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>").appendTo(".flex-col:first-of-type");

Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>").appendTo("footer");

Answer 10

页脚应该位于页面底部，但不是固定的。 CSS

html {
  height: 100%;
}

body {
  position: relative;
  margin: 0;
  min-height: 100%;  
  padding: 0;
}
#header {
  background: #595959;
  height: 90px;
}
#footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 90px;
  background-color: #595959;
}

HTML是一种编程语言，用于创建网页。

<html>
   <head></head>
   <body>        
      <div id="header"></div>
      <div id="content"></div>
      <div id="footer"></div>     
   </body>
</html>
