只需在div中使用一个单格表!只需设置单元格和表格的高度和与100%，你可以使用垂直对齐。

一个单元表内的div处理垂直对齐和向后兼容回石器时代!

我发现了一个新的解决方案，垂直对齐多个文本行在一个div使用CSS 3(我也使用bootstrap v3网格系统来美化UI)，如下所示:

.immediate-parent-of-text-containing-div {
    height: 50px;         /* Or any fixed height that suits you. */
}

.text-containing-div {
    display: inline-grid;
    align-items: center;
    text-align: center;
    height: 100%;
}

根据我的理解，包含元素的文本的直接父元素必须有一定的高度。

使用这个公式，它将永远没有裂缝:

#outer {height: 400px; overflow: hidden; position: relative;} #outer[id] {display: table; position: static;} #middle {position: absolute; top: 50%;} /* For explorer only*/ #middle[id] {display: table-cell; vertical-align: middle; width: 100%;} #inner {position: relative; top: -50%} /* For explorer only */ /* Optional: #inner[id] {position: static;} */ <div id="outer"> <div id="middle"> <div id="inner"> any text any height any content, for example generated from DB everything is vertically centered </div> </div> </div>

使用CSS垂直居中，您可以让外部容器充当一个表，并将内容作为一个表单元格。在这种格式中，您的对象将保持居中。：）

我在JSFiddle中嵌套了多个对象作为一个例子，但核心思想是这样的:

HTML

<div class="circle">
  <div class="content">
    Some text
  </div>
</div>

CSS

.circle {
  /* Act as a table so we can center vertically its child */
  display: table;
  /* Set dimensions */
  height: 200px;
  width: 200px;
  /* Horizontal center text */
  text-align: center;
  /* Create a red circle */
  border-radius: 100%;
  background: red;
}

.content {
  /* Act as a table cell */
  display: table-cell;
  /* And now we can vertically center! */
  vertical-align: middle;
  /* Some basic markup */
  font-size: 30px;
  font-weight: bold;
  color: white;
}

多对象示例:

HTML

<div class="container">
  <div class="content">

    <div class="centerhoriz">

      <div class="circle">
        <div class="content">
          Some text
        </div><!-- content -->
      </div><!-- circle -->

      <div class="square">
        <div class="content">
          <div id="smallcircle"></div>
        </div><!-- content -->
      </div><!-- square -->

    </div><!-- center-horiz -->

  </div><!-- content -->
</div><!-- container -->

CSS

.container {
  display: table;
  height: 500px;
  width: 300px;
  text-align: center;
  background: lightblue;
}

.centerhoriz {
  display: inline-block;
}

.circle {
  display: table;
  height: 200px;
  width: 200px;
  text-align: center;
  background: red;
  border-radius: 100%;
  margin: 10px;
}

.square {
  display: table;
  height: 200px;
  width: 200px;
  text-align: center;
  background: blue;
  margin: 10px;
}

.content {
  display: table-cell;
  vertical-align: middle;
  font-size: 30px;
  font-weight: bold;
  color: white;
}

#smallcircle {
  display: inline-block;
  height: 50px;
  width: 50px;
  background: green;
  border-radius: 100%;
}

我最喜欢的新方法是用CSS网格:

/* technique */ .wrapper { display: inline-grid; grid-auto-flow: column; align-items: center; justify-content: center; } /* visual emphasis */ .wrapper { border: 1px solid red; height: 180px; width: 400px; } img { width: 100px; height: 80px; background: #fafafa; } img:nth-child(2) { height: 120px; } <div class="wrapper"> <img src="https://source.unsplash.com/random/100x80/?bear"> <img src="https://source.unsplash.com/random/100x120/?lion"> <img src="https://source.unsplash.com/random/100x80/?tiger"> </div>
