[英]Issue in fixing the content in the center both horizontally and vertically
我在垂直和水平方向固定内容时遇到问题。 当我在开发人员工具中进行检查时,我的容器流体没有覆盖页脚。 我看过其他堆栈,但仍然无法弄清楚。 这是我的codepen。 https://codepen.io/anon/pen/yqdbWd
我要删除侧边栏,因为它只有一个页面,内容很少。 我包括了我的问题的屏幕截图。 而且我的容器流体不会占用整个页面。
最后,我想知道是否有办法像这样大大缩短我的hr线的长度。
这是我到目前为止完成的代码。

这是CSS
body,html {
height: 100%;
background:#333A4D;
}
.navbar{
margin: 10px;
background: #333A4D;
padding: 20px;
}
.nav-link{
font-size: 25px;
line-height: 32px;
color: #F3B0B6;
}
.list-inline-item{ margin-left: 1rem; }
.jumbotron{ background: none; }
.text-border{
display: block;
height: 1px;
border: 0;
border-top: 4px solid #F3B0B6;
}
.lead{
text-transform: uppercase;
color: #F3B0B6;
font-size: 25px;
line-height: 31px;
}
@media (min-width: 48em) {
.navbar-brand{
float: left;
}
.nav{
float: right;
}
}
您增加了height: 100%;
到您的主要部分,它将使其与屏幕一样大,但是标题将您的主要部分向下推,这就是滚动条出现的原因。
然后我添加了position: absolute;
在您的页脚上贴上底部并添加display: flex;
用一些技巧来代替float: left & float: right
。
也缩短线路我换成<div class="col-4 mx-auto">
与<div class="col-6 mx-auto">
如果你想缩短它更使用<div class="col-3 mx-auto">
甚至更低的值。

而不是在jumbotron .row
上使用height:100%,而是使其成为容器流体flexbox列( d-flex flex-column
),然后在jumbotron .row
上使用flex-grow-1
,以填充导航器之间的剩余高度。和页脚。 这将消除滚动条。

<div class="row align-items-center flex-grow-1">

至于将超大屏幕放到页面中央,请将导航栏fixed-top
这样就不会压低超大屏幕内容并使它偏离中心。 还要去掉巨无霸(mb-0)的底部边缘。 这是一个通用的Bootstrap 4示例
