粘性Flexbox页脚不起作用

标签： html css twitter-bootstrap flexbox

我试图通过flexbox制作贴纸页脚;但是，它没有用。它仍然占据屏幕的一半左右。

这是我的HTML和CSS代码：

＆＃13;
＆＃13; 
.page {
    flex: 1 0 auto;
}
html {
  height: 100%;
}
body {
    min-height: 100%;
    display: flex;
    flex-direction: column;
}
＆＃13; 
<div class="page">
    <div class="contactandsocial">
        <p class="phonenumbers">
            Brockville - (613) 865-7733 &nbsp &nbsp
            Cornwall - (343) 885-7733 &nbsp &nbsp
            Kingston - (613) 817-7733 &nbsp &nbsp
            Ottawa - (613) 454-7733
        </p>
        <form action="http://www.truespeed.ca/contact">

由于我们没有您的最小代码段，因此这里有一个示例代码，说明如何完成。

＆＃13; 
html, body {
  margin: 0;
}
body {
  display: flex;           /*  IE 11/10 min-height bug fix - or an extra wrapper  */
  background: red;
}                          /*  in the markup having display: flex;                */
.page {
  width: 100%;
  min-height: 100vh;
  display: flex;
  flex-direction: column;
}
.content {

将footer放在.page之外，并将.page设置为flex: 1（注释一些页脚链接以便更好地欣赏）：

＆＃13;
＆＃13; 
.page {
  flex: 1;
}
html {
  height: 100%;
}
body {
  min-height: 100%;
  display: flex;
  flex-direction: column;
}
footer {
  background: lightgray;
}
＆＃13; 
<div class="page">
  Content

<footer>
  <div class="container-fluid">

你仍然可以这样做

<main>
    Main
</main>
<footer>
    Footer
</footer>

html {
    height: 100%;
}

body {
    height: 100%;
}

main {
    height: 100%;
    padding-bottom: 200px;
    background-color: #ccc;
}

footer {
    height: 200px;
    margin-top: -200px;
    position: relative;
}

我不建议在页面中为所有网格使用flexbox。
