如何在Bootstrap中将容器垂直居中？

神乐神奇2020-03-23

我正在寻找一种将containerdiv 垂直居中放置jumbotron在页面中间的方法。

在.jumbotron必须适应于屏幕的整个高度和宽度。的.containerdiv有一个宽度1025px和应在该页面（垂直中心）的中间。

我希望此页面的大屏幕适应屏幕的高度和宽度，并且容器垂直于大屏幕垂直居中。我该如何实现？

.jumbotron {
  height:100%;
  width:100%;
}
.container {
  width:1025px;
}
.jumbotron .container {
  max-width: 100%;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<div class="jumbotron">
    <div class="container text-center">
        <h1>The easiest and powerful way</h1>
        <div class="row">
            <div class="col-md-7">
                 <div class="top-bg"></div>
            </div>

            <div class="col-md-5 iPhone-features" style="margin-left:-25px;">
                <ul class="top-features">
                    <li>
                        <span><i class="fa fa-random simple_bg top-features-bg"></i></span>
                        <p><strong>Redirect</strong><br>Visitors where they converts more.</p>
                    </li>
                    <li>
                        <span><i class="fa fa-cogs simple_bg top-features-bg"></i></span>

这是我用于垂直对齐内容的方式-带有自举3行的顶部/中央/底部。引导3个具有相同高度并垂直对齐的列。

/* columns of same height styles */

.row-full-height {
  height: 100%;
}
.col-full-height {
  height: 100%;
  vertical-align: middle;
}
.row-same-height {
  display: table;
  width: 100%;
  /* fix overflow */
  table-layout: fixed;
}
.col-xs-height {
  display: table-cell;
  float: none !important;
}

@media (min-width: 768px) {
  .col-sm-height {
    display: table-cell;
    float: none !important;
  }
}
@media (min-width: 992px) {
  .col-md-height {
    display: table-cell;
    float: none !important;
  }
}
@media (min-width: 1200px) {
  .col-lg-height {
    display: table-cell;
    float: none !important;
  }
}
/* vertical alignment styles */

.col-top {
  vertical-align: top;
}
.col-middle {
  vertical-align: middle;
}
.col-bottom {
  vertical-align: bottom;

<div class="container">

<h2>Demo 1</h2>
<div class="row">
  <div class="row-same-height">
    <div class="col-xs-3 col-xs-height">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed tempus tincidunt porttitor. Praesent vehicula aliquam enim. Fusce non luctus eros, sit amet consequat velit. Pellentesque volutpat est et est imperdiet pharetra. Integer vestibulum feugiat malesuada. Proin a felis ut libero vestibulum fermentum ut sit amet est. Morbi placerat eget lacus sed sagittis. Nullam eu elit gravida arcu viverra facilisis. Quisque laoreet enim neque, ut consequat sem tincidunt at. Fusce lobortis scelerisque libero, eget vulputate neque. </div>
    <div class="col-xs-3 col-xs-height col-top">2st column</div>
    <div class="col-xs-3 col-xs-height col-middle">3st column</div>
    <div class="col-xs-3 col-xs-height col-bottom">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed tempus tincidunt porttitor. Praesent vehicula aliquam enim. Fusce non luctus eros, sit amet consequat velit. Pellentesque volutpat est et est imperdiet pharetra.</div>
  </div>
</div><!-- ./row -->
</div><!-- ./container -->

这是一个JSFiddle演示。

如果您使用的是Bootstrap 4，则只需添加2个div：

.jumbotron{
  height:100%;
  width:100%;
}

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>    
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<body>
  <div class="jumbotron">
    <div class="d-table w-100 h-100">
      <div class="d-table-cell w-100 h-100 align-middle">
        <h5>
          your stuff...
        </h5>
        <div class="container">
          <div class="row">
            <div class="col-12">
              <p>
                More stuff...
              </p>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</body>

类：d-table，d-table-cell，w-100，h-100和align-middle可以胜任

  height: 100%;
  width: 100%;
}

.jumbotron {
   display: table-cell;
   vertical-align: middle;
}

灵活的盒子方式

现在，通过使用弹性框布局，垂直对齐非常简单。如今，除Internet Explorer 8和9之外，各种 Web浏览器都支持此方法。因此，对于IE8 / 9，我们需要使用一些hacks / polyfill或其他方法。

在下面的内容中，我将向您展示如何仅用3行文本（不管使用旧的flexbox语法）如何做到这一点。

注意：最好使用其他类，而不要进行更改.jumbotron以实现垂直对齐。我将使用vertical-center类名作为实例。

实施例在此 （A 镜子上jsbin） 。

<div class="jumbotron vertical-center"> <!-- 
                      ^--- Added class  -->
  <div class="container">
    ...
  </div>
</div>

.vertical-center {
  min-height: 100%;  /* Fallback for browsers do NOT support vh unit */
  min-height: 100vh; /* These two lines are counted as one :-)       */

  display: flex;
  align-items: center;
}

重要说明（在演示中考虑）：

一个百分比值height或min-height性质是相对height父元素的，因此，你应该指定height明确的母公司。
由于简洁，在发布的代码段中省略了供应商前缀/旧的flexbox语法，但在线示例中存在。
在一些旧的Web浏览器如Firefox 9 ^{（在我测试过）}，柔性容器- .vertical-center在这种情况下-不会占用可用空间父里面，所以我们需要指定width类似属性：width: 100%。
同样在如上所述的某些Web浏览器中，.container在这种情况下，伸缩项可能不会水平出现在中央。看来所施加的左/右margin的auto没有在柔性项目产生任何影响。
因此，我们需要将其对齐box-pack / justify-content。

有关列的更多详细信息和/或垂直对齐，可以参考以下主题：

与Bootstrap 3垂直对齐

传统Web浏览器的传统方式

这是我回答这个问题时写的旧答案。此方法已在此处进行了讨论，并且应该也可以在Internet Explorer 8和9中使用。我将简短地解释一下：

In inline flow, an inline level element can be aligned vertically to the middle by vertical-align: middle declaration. Spec from W3C:

middle
Align the vertical midpoint of the box with the baseline of the parent box plus half the x-height of the parent.

In cases that the parent - .vertical-center element in this case - has an explicit height, by any chance if we could have a child element having the exact same height of the parent, we would be able to move the baseline of the parent to the midpoint of the full-height child and surprisingly make our desired in-flow child - the .container - aligned to the center vertically.

Getting all together

That being said, we could create a full-height element within the .vertical-center by ::before or ::after pseudo elements and also change the default display type of it and the other child, the .container to inline-block.

Then use vertical-align: middle; to align the inline elements vertically.

Here you go:

<div class="jumbotron vertical-center">
  <div class="container">
    ...
  </div>
</div>

.vertical-center {
  height:100%;
  width:100%;

  text-align: center;  /* align the inline(-block) elements horizontally */
  font: 0/0 a;         /* remove the gap between inline(-block) elements */
}

.vertical-center:before {    /* create a full-height inline block pseudo=element */
  content: " ";
  display: inline-block;
  vertical-align: middle;    /* vertical alignment of the inline element */
  height: 100%;
}

.vertical-center > .container {
  max-width: 100%;

  display: inline-block;
  vertical-align: middle;  /* vertical alignment of the inline element */
                           /* reset the font property */
  font: 16px/1 "Helvetica Neue", Helvetica, Arial, sans-serif;
}

WORKING DEMO.

Also, to prevent unexpected issues in extra small screens, you can reset the height of the pseudo-element to auto or 0 or change its display type to none if needed so:

@media (max-width: 768px) {
  .vertical-center:before {
    height: auto;
    /* Or */
    display: none;
  }
}

UPDATED DEMO

And one more thing:

如果容器周围有footer/个header部分，最好将这些元素正确放置（relative，absolute？取决于您）。并增加一个较高的z-index值（以确保），以使它们始终位于其他元素的顶部。

村村2020/03/23 11:03:28

在IE，Firefox和Chrome中进行了测试。

.parent-container {
    position: relative;
    height:100%;
    width: 100%;
}

.child-container {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

<div class="parent-container">
    <div class="child-container">
        <h2>Header Text</h2>
        <span>Some Text</span>
    </div>
</div>

更新2019

Bootstrap 4包含flexbox，因此垂直居中的方法要容易得多，并且不需要额外的CSS。

只需使用d-flex和align-items-center实用程序类即可。

<div class="jumbotron d-flex align-items-center">
  <div class="container">
    content
  </div>
</div>

http://www.codeply.com/go/ui6ABmMTLv

重要：垂直居中是相对于高度。您要居中的项目的父容器必须具有定义的高度。如果要使用页面的高度vh-100或使用min-vh-100父级！例如：

<div class="jumbotron d-flex align-items-center min-vh-100">
  <div class="container text-center">
    I am centered vertically
  </div>
</div>

另请参见：Bootstrap 4中的垂直对齐中心

小卤蛋2020/03/23 11:03:28

在Bootstrap 4中：

以水平居中的孩子，使用引导-4类：

justify-content-center

以垂直居中的孩子，使用引导-4类：

 align-items-center

但请记住不要忘记将d-flex类与bootstrap-4实用程序类一起使用，就像这样

<div class="d-flex justify-content-center align-items-center" style="height:100px;">
    <span class="bg-primary">MIDDLE</span>    
</div>

注意：如果此代码不起作用，请确保添加bootstrap-4实用程序

我知道这不是此问题的直接答案，但可能会对某人有所帮助

番长樱梅2020/03/23 11:03:28

添加Bootstrap.css，然后将其添加到您的CSS

   
html, body{height:100%; margin:0;padding:0}
 
.container-fluid{
  height:100%;
  display:table;
  width: 100%;
  padding: 0;
}
 
.row-fluid {height: 100%; display:table-cell; vertical-align: middle;}
 
 

.centering {
  float:none;
  margin:0 auto;
}

Now call in your page 

<div class="container-fluid">
    <div class="row-fluid">
        <div class="centering text-center">
           Am in the Center Now :-)
        </div>
    </div>
</div>
