问题描述
我需要在我的页面上放置一个粘性页脚,但是我没有为页脚设置一个确定的高度。在较小的屏幕上 - 行的大小调整和页脚变长。
因此,getbootstrap提供的默认粘性页脚示例不起作用,因为它需要固定页脚高度。
任何方式来实现这一点?
/ *粘滞的页脚样式
---------- ---------------------------------------- * /
html {
位置:相对;
最低身高:100%;
}
body {
/ *边距底部高度* /
margin-bottom:60px;
}
.footer {
position:absolute;
bottom:0;
宽度:100%;
/ *设置页脚的固定高度* /
height:60px;
line-height:60px; / *垂直居中文本* /
背景颜色:#f5f5f5;
}
/ *自定义页面CSS
------------------------ -------------------------- * /
/ *模板或粘滞页脚方法不需要。 * /
body> .container {
padding:60px 15px 0;
}
.footer> .container {
padding-right:15px;
padding-left:15px;
}
代码{
font-size:80%;
现在Bootstrap 4是flexbox ,粘性页脚可以使用...
< wrapper class =d-flex flex-column>
< nav>
< / nav>
< main class =flex-fill>
< / main>
< footer>
< / footer>
< / wrapper>
body,wrapper {
min-height:100vh;
}
.flex-fill {
flex:1 1 auto;
}
演示:(4.0.0)
$ b 注意:
flex-fill
实用程序类将包含在发布。所以在发布之后,不需要额外的flex-fill CSS。 I need to put a sticky footer on my pages , however i don't have a definite height set for my footer . On smaller screens - the rows resize and footer becomes longer .
Therefore , the default sticky footer example provided on getbootstrap does not work since it requires a fixed footer height.
Any way to implement this ?
/* Sticky footer styles
-------------------------------------------------- */
html {
position: relative;
min-height: 100%;
}
body {
/* Margin bottom by footer height */
margin-bottom: 60px;
}
.footer {
position: absolute;
bottom: 0;
width: 100%;
/* Set the fixed height of the footer here */
height: 60px;
line-height: 60px; /* Vertically center the text there */
background-color: #f5f5f5;
}
/* Custom page CSS
-------------------------------------------------- */
/* Not required for template or sticky footer method. */
body > .container {
padding: 60px 15px 0;
}
.footer > .container {
padding-right: 15px;
padding-left: 15px;
}
code {
font-size: 80%;
}
Now that Bootstrap 4 is flexbox, a sticky footer can be done using...
<wrapper class="d-flex flex-column">
<nav>
</nav>
<main class="flex-fill">
</main>
<footer>
</footer>
</wrapper>
body, wrapper {
min-height:100vh;
}
.flex-fill {
flex:1 1 auto;
}
Demo: Bootstrap 4 Sticky Footer (4.0.0)
Note: The flex-fill
utility class will be included in the next Bootstrap 4.1 release. So after that release the extra CSS for flex-fill won't be needed.
