如何在div中垂直对齐元素?

我有一个div与两个图像和一个h1。所有这些都需要在div中垂直对齐，彼此相邻。其中一个图像需要在div中绝对定位。

要在所有常见浏览器上工作，需要什么样的CSS ?

<div id="header">
  <img src=".." ></img>
  <h1>testing...</h1>
  <img src="..."></img>
</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%;
}

结果

我已经使用以下解决方案(没有定位和线高)一年多了，它适用于Internet Explorer 7和Internet Explorer 8。

<style>
.outer {
    font-size: 0;
    width: 400px;
    height: 400px;
    background: orange;
    text-align: center;
    display: inline-block;
}

.outer .emptyDiv {
    height: 100%;
    background: orange;
    visibility: collapse;
}

.outer .inner {
    padding: 10px;
    background: red;
    font: bold 12px Arial;
}

.verticalCenter {
    display: inline-block;
    *display: inline;
    zoom: 1;
    vertical-align: middle;
}
</style>

<div class="outer">
    <div class="emptyDiv verticalCenter"></div>
    <div class="inner verticalCenter">
        <p>Line 1</p>
        <p>Line 2</p>
    </div>
</div>

在父div中创建中央子div的三种方法

绝对定位法 Flexbox方法变换/翻译方法

Demo

/* Absolute Positioning Method */ .parent1 { background: darkcyan; width: 200px; height: 200px; position: relative; } .child1 { background: white; height: 30px; width: 30px; position: absolute; top: 50%; left: 50%; margin: -15px; } /* Flexbox Method */ .parent2 { display: flex; justify-content: center; align-items: center; background: darkcyan; height: 200px; width: 200px; } .child2 { background: white; height: 30px; width: 30px; } /* Transform/Translate Method */ .parent3 { position: relative; height: 200px; width: 200px; background: darkcyan; } .child3 { background: white; height: 30px; width: 30px; position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); } <div class="parent1"> <div class="child1"></div> </div> <hr /> <div class="parent2"> <div class="child2"></div> </div> <hr /> <div class="parent3"> <div class="child3"></div> </div>

对我来说，它是这样工作的:

<div style="width:70px; height:68px; float:right; display: table-cell; line-height: 68px">
    <a href="javascript:void(0)" style="margin-left: 4px; line-height: 2" class="btn btn-primary">Login</a>
</div>

“a”元素转换为按钮，使用Bootstrap类，它现在垂直居中在一个外部的“div”。
