如何将旋转木马内的内容垂直居中？

Question

我所指的旋转木马是Bootstrap的旋转木马（http://getbootstrap.com/examples/carousel/）。

我正在使用示例中的类似代码，但我无法将内容放在父级中间。

如您所见，内容不居中。我已经尝试设置轮播标题{vertical-align：middle;}，但没有任何变化。

<div class="carousel-inner">
    <div class="item active">
        <div class="container">
            <div class="carousel-caption">
                !!contents!!
            </div>
        </div>
    </div>
</div>

这是示例中的相同代码。我怎样才能将旋转木马标题垂直居中？

中的标题文字垂直和水平居中

Answer 2

用于IE8及以上版本

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

Answer 3

最简单的方法是使用display:inline-block和line-height的组合，例如。

.container {
    line-height: 100px // height of your carousel
}

.carousel-caption {
    line-height: normal; // restore original line height here
    display: inline-block;
    vertical-align: middle;
}
