设置与另一个div内嵌的div内的内容对齐

Question

我有一个页面，两个div并排排列在三分之一到三分之二的位置。这些包含在一个父div中。我的一个div有一个图像，我想要做的是有能力将图像垂直对齐到父div的顶部，中间或底部，其高度由第二个div中的文本数量定义。理想情况下，我希望能够为图片或内容添加一个类，这将设置对齐方式。

Answer 2

也许你可以使用display: table-cell

与HTML：

<div class="area vertical-top"> 
    <img src="http://lorempixel.com/300/150/cats"> 
</div> 

<div class="area"> 
    <p>lorem ipsum...</p> 
</div> 

和CSS：

.area { 
    background: red; 
    display:table-cell; 
    vertical-align: top; 
} 

.vertical-bottom { 
     vertical-align: bottom; 
} 

.vertical-middle { 
     vertical-align: middle; 
}
