我有以下页面(deadlink: http://www.workingstorage.com/Sample.htm)，有一个脚注，我不能坐在页面的底部。
我想让页脚
当页面较短且屏幕未被填充时，坚持在窗口底部 当有超过一个屏幕的内容时，保持在文档末尾，并像往常一样向下移动(而不是重叠内容)。
CSS是继承的，让我困惑。我似乎不能正确地改变它，把一个最小高度的内容或使页脚到底部。

对我有用。
#container{
height:100vh;
margin:0;
display:flex;
flex-direction:column;
}
#footer{
margin-top:auto;
}
<div id="container">
<div id="header">header</div>
<div id="body">body</div>
<div id="footer">footer</div>
</div>
#{容器 身高:100 vh; 保证金:0; 显示:flex; flex-direction:列; ｝ #页脚{ margin-top:汽车; ｝ < div id = "容器" > < div id = "头" >头< / div > 身体< div id = "身体" > < / div > < div id = "脚注" >页脚< / div > < / div >

然而，另一个非常简单的解决方案是:
html, body {
height: 100%;
width: 100%;
margin: 0;
display: table;
}
footer {
background-color: grey;
display: table-row;
height: 0;
}
js小提琴
诀窍是使用display:table表示整个文档，使用display:table-row(高度为0)表示页脚。
由于页脚是唯一显示为表行的子主体，因此它呈现在页面底部。
这就是所谓的粘性页脚。在谷歌上搜索它会出现很多结果。我成功地使用过CSS Sticky Footer。但还有更多。
* { margin: 0; } html, body { height: 100%; } .wrapper { min-height: 100%; height: auto !important; height: 100%; margin: 0 auto -4em; } .footer, .push { height: 4em; } <html> <head> <link rel="stylesheet" href="layout.css" ... /> </head> <body> <div class="wrapper"> <p>Your website content here.</p> <div class="push"></div> </div> <div class="footer"> <p>Copyright (c) 2008</p> </div> </body> </html>
此代码的源代码
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="main.css" />
</head>
<body>
<div id="page-container">
<div id="content-wrap">
<!-- all other page content -->
</div>
<footer id="footer"></footer>
</div>
</body>
</html>
#page-container {
position: relative;
min-height: 100vh;
}
#content-wrap {
padding-bottom: 2.5rem; /* Footer height */
}
#footer {
position: absolute;
bottom: 0;
width: 100%;
height: 2.5rem; /* Footer height */
}
我在我的许多项目中都使用过，从来没有遇到过任何问题:)
供您参考，代码片段
* { margin: 0; } html, body { height: 100%; } .wrapper { min-height: 100%; height: auto !important; /* This line and the next line are not necessary unless you need IE6 support */ height: 100%; margin: 0 auto -50px; /* the bottom margin is the negative value of the footer's height */ background:green; } .footer, .push { height: 50px; /* .push must be the same height as .footer */ } .footer{ background:gold; } <html> <head> <meta charset="utf-8"> <title>Untitled Document</title> </head> <body> <div class="wrapper"> Content Area </div> <div class="push"> </div> <div class="footer"> Footer Area </div> </body> </html>
这就是我解决同样问题的方法
html { height: 100%; box-sizing: border-box; } *, *:before, *:after { box-sizing: inherit; } body { position: relative; margin: 0; padding-bottom: 6rem; min-height: 100%; font-family: "Helvetica Neue", Arial, sans-serif; } .demo { margin: 0 auto; padding-top: 64px; max-width: 640px; width: 94%; } .footer { position: absolute; right: 0; bottom: 0; left: 0; padding: 1rem; background-color: #efefef; text-align: center; } <div class="demo"> <h1>CSS “Always on the bottom” Footer</h1> <p>I often find myself designing a website where the footer must rest at the bottom of the page, even if the content above it is too short to push it to the bottom of the viewport naturally.</p> <p>However, if the content is taller than the user’s viewport, then the footer should disappear from view as it would normally, resting at the bottom of the page (not fixed to the viewport).</p> <p>If you know the height of the footer, then you should set it explicitly, and set the bottom padding of the footer’s parent element to be the same value (or larger if you want some spacing).</p> <p>This is to prevent the footer from overlapping the content above it, since it is being removed from the document flow with <code>position: absolute; </code>.</p> </div> <div class="footer">This footer will always be positioned at the bottom of the page, but <strong>not fixed</strong>.</div>
