我想用CSS垂直居中放置一个div。我不需要表或JavaScript,只需要纯CSS。我找到了一些解决方案,但都缺少Internet Explorer 6支持。

<body>
    <div>Div to be aligned vertically</div>
</body>

如何在所有主要浏览器(包括Internet Explorer 6)中垂直居中放置div?


当前回答

最好的做法是:

#vertalign{
  height: 300px;
  width: 300px;
  position: absolute;
  top: calc(50vh - 150px); 
}

150像素,因为在本例中,这是div高度的一半。

其他回答

我认为,对于所有不使用Flexbox的浏览器来说,“alignitems:center;”是一种显示:表格和垂直对齐:中间;的组合;。

CSS

.vertically-center
{
    display: table;

    width: 100%;  /* Optional */
    height: 100%; /* Optional */
}

.vertically-center > div
{
    display: table-cell;
    vertical-align: middle;
}

HTML

<div class="vertically-center">
    <div>
        <div style="border: 1px solid black;">some text</div>
    </div>
</div>

Billbad的答案只适用于固定宽度的.intern除法。此解决方案通过将属性textalign:center添加到.outer div中来实现动态宽度。

.外部{位置:绝对;显示:表格;宽度:100%;高度:100%;文本对齐:居中;}.中间{显示:表格单元格;垂直对齐:中间;}.内部{文本对齐:居中;显示:内联块;宽度:自动;}<div class=“outer”><div class=“middle”><div class=“inner”>所容纳之物</div></div></div>

只需这样做:在div中添加类:

.modal {
  margin: auto;
  position: absolute;
  top: 0;
  right: 0;
  left: 0;
  bottom: 0;
  height: 240px;
}

请阅读本文以获得解释。注:高度是必需的。

我用这个。它适用于Internet Explorer 8和更高版本:

高度:268px-用于显示:表的作用类似于最小高度。

CSS:

* {
  padding: 0;
  margin: 0;
}
body {
  background: #cc9999;
}
p {
  background: #f0ad4e;
}
#all {
  margin: 200px auto;
}
.ff-valign-wrap {
  display: table;
  width: 100%;
  height: 268px;
  background: #ff00ff;
}
.ff-valign {
  display: table-cell;
  height: 100%;
  vertical-align: middle;
  text-align: center;
  background: #ffff00;
}

HTML格式:

<body>

  <div id="all">
    <div class="ff-valign-wrap">
      <div class="ff-valign">
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Amet, animi autem doloribus earum expedita, ipsum laboriosam nostrum nulla officiis optio quam quis quod sunt tempora tenetur veritatis vero voluptatem voluptates?</p>

      </div>
    </div>
  </div>

</body>

这里有一个简单的方法,几乎没有代码:

CSS代码:

.main{
    height: 100%;
}

.center{
    top: 50%;
    margin-top: 50%;
}

HTML代码:

<div class="main">
    <div class="center">
        Hi, I am centered!
    </div>
</div>

您的文本将位于页面中间!
