将页脚固定到页面底部

Question

虽然我网站上的大多数页面都有足够的内容来将页脚推到页面底部，但对于大多数人来说。我想知道从现在开始不管屏幕大小，它总是固定在底部。

我尝试了多种方法，例如底部：0x;position:absolute: 等。似乎从来没有很好地工作，偶尔使用其中一些示例将页脚推出其容器以固定到底部.

包括页脚两部分（页脚和版权栏）的 HTML 和 CSS。无论如何，它们都在<section id="footer"> div 内部。

我取消了让它坚持下去的尝试，以便人们现在可以查看它并查看当前代码要修改的内容。

CSS：

#footer {
    background-color: #F3F3F3;
    padding-top: 10px;
    padding-bottom: 0px;
}

Answer 1

为您的footer：

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

为您的body：

body {
    margin-bottom:50px;
}

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

div {
  margin: 20px 20px;
}

body {
  margin-bottom: 50px;
}

<div>
  Although most pages on my site have enough content to push the footer to the bottom of the page for most people. I would like to know it's always fixed to the bottom regardless of screen size from now on anyway. I've tried a number of ways such as bottom:
  0x; position:absolute: etc. Never seems to work very well, occasionally pushes the footer out of it's container to fix to the bottom using some of those examples right there. Included is the HTML and CSS for the two parts of the footer (footer & copyright
  bar). They're both inside of a div anyway. I removed my attempts at getting it to stick so people can have a look at it right now and see what the current code is to amend. Although most pages on my site have enough content to push the footer to the

Answer 2

我们可以将 FlexBox 用于 Sticky Footer 和 Header，而无需在 CSS 中使用 POSITIONS。

.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>

注意：检查浏览器是否支持 FlexBox。 caniuse

Answer 3

像这样在选择器#footer下面添加position:fixed;和bottom:0;：

demo

CSS

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

Answer 4

设置

html, body {
    height: 100%;
}

将整个内容包裹在 div 中的页脚之前。

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

您可以根据您希望在浏览器窗口底部显示的页脚量来调整最小高度。如果将其设置为 90%，则在滚动之前将显示 10% 的页脚。

Answer 5

下面是一个可行的简单 CSS 解决方案：

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

Answer 6

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 7

这段代码对我有用：

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

您应该添加的重要内容 bottom:0; 和 position: fixed;

Answer 8

我发现粘性页脚解决方案在响应式网站上有点痛苦，因为导航和页脚的高度可能因设备而异。如果您只关心在现代浏览器上工作，您可以使用一点 Javascript 来实现您的目标。

如果这是您的 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

除非您以这种方式设置页脚元素，否则您的页脚元素不会固有地固定在视口的底部。
因此，如果您碰巧有一个页面没有足够的内容将其一直向下推它最终会出现在视口中间的某个地方；看起来很尴尬，不知道自己该怎么办，就像我高中的第一天一样。

通过声明fixed 规则来定位元素非常棒，如果您总是希望页脚可见，而不管初始页面高度如何 - 但请记住设置底部边距，以便它不会覆盖其上的最后一点内容页。如果您的页脚具有动态高度，这将变得很棘手；这通常是响应式网站的情况，因为它具有堆叠元素的性质。

您会发现与absolute 定位类似的问题。尽管它确实将有问题的元素从文档的自然流中剔除，但如果您发现自己的页面几乎没有内容可以充实它，它仍然不会将其固定到屏幕底部。

考虑通过以下方式实现：

1. 为<body> 和<html> 标签声明高度值
2. 向嵌套的包装元素声明minimum-height 值，通常是包装正文结构中包含的所有后代元素的元素（这不包括您的footer 元素）

Code Pen Example

$("#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");
});

$("#resetBodyContent").on("click", function() {
  $(".flex-col p").remove();
});

$("#addFooterContent").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("footer");
});

$("#resetFooterContent").on("click", function() {
  $("footer p").remove();
});

Answer 10

页脚位于页面底部，但不是固定。

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

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

Answer 11

您可以使用网格布局。它比 Flexbox 更新，在浏览器中的支持较少。

检查一下：

HTML

<body>
  <div class="content">
    content
  </div>
  <footer class="footer"></footer>
</body>

CSS

html {
  height: 100%;
}

body {
  min-height: 100%;
  display: grid;
  grid-template-rows: 1fr auto;
}   

.footer {
  grid-row-start: 2;
  grid-row-end: 3;
}

一个非常简单的示例，展示了如何在应用程序布局的底部修复页脚。

/* Styles go here */
html{ height: 100%;}
body{ min-height: 100%; background: #fff;}
.page-layout{ border: none; width: 100%; height: 100vh; }
.page-layout td{ vertical-align: top; }
.page-layout .header{ background: #aaa; }
.page-layout .main-content{ height: 100%; background: #f1f1f1; text-align: center; padding-top: 50px; }
.page-layout .main-content .container{ text-align: center; padding-top: 50px; }
.page-layout .footer{ background: #333; color: #fff; } 

<!DOCTYPE html>
<html>

  <head>
    <link data-require="bootstrap@*" data-semver="4.0.5" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" />
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
  </head>

  <body>
    <table class="page-layout">
      <tr>
        <td class="header">
          <div>
            This is the site header.
          </div>
        </td>
      </tr>
      <tr>
        <td class="main-content">
          <div>
            <h1>Fix footer always to the bottom</h1>
            <div>
              This is how you can simply fix the footer to the bottom.
            </div>
            <div>
              The footer will always stick to the bottom until the main-content doesn't grow till footer.
            </div>
            <div>
              Even if the content grows, the footer will start to move down naturally as like the normal behavior of page.
            </div>
          </div>
        </td>
      </tr>
      <tr>
        <td class="footer">
          <div>
            This is the site footer.
          </div>
        </td>
      </tr>
    </table>
  </body>

</html>

Answer 14

使用 Flex 和 Bootstrap4（如果不使用 Bootstrap4，使用 flex 属性可以达到相同的效果）

<body class="d-flex flex-column">
    <div>Header</div>
    <div>Main container</div>
    <div class="mt-auto">Footer</div>
</body>
