尽管我网站上的大多数页面都有足够的内容来将页脚推到大多数人的页面底部。我想知道从现在开始不管屏幕尺寸如何，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，偶尔使用其中的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。<section id="footer"> div反正他们都在里面。

我删除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。

我们可以在不使用 CSS 中的 POSITIONS 的情况下将FlexBox用于 Sticky Footer和Header 。

.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>

放

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%;
}

您可以根据要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。

    position: fixed;

    height: 35px;

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();
  }
});

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位置；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。

如果无论初始页面高度如何，您总是希望页脚可见，那么通过声明fixed规则来定位元素非常好 - 但请记住设置底部边距，以便它不会覆盖该页面上的最后一点内容。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，因为它本质上是要堆叠的元素。

absolute您会发现与定位类似的问题。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来充实它，它仍然不会将其固定到屏幕底部。

考虑通过以下方式实现这一目标：

  1. <body>声明&<html>标签的高度值
  2. minimum-height为嵌套的包装元素声明一个值，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）

代码笔示例

$("#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");

  $("<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");

您可以使用网格布局。它比 Flexbox 更新，在浏览器中的支持较少。

一探究竟：

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-end: 3;
}

    <table class="page-layout">

          <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>

使用 Flex 和 Bootstrap4（如果你不使用 Bootstrap4，你可以使用 flex 属性达到相同的结果）

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