javascript – 如何使旋转木马内的内容垂直居中？

参见英文答案 > How to vertically center a Bootstrap carousel-caption?                                    1个
我指的旋转木马是Bootstrap的旋转木马(http://getbootstrap.com/examples/carousel/).

我正在使用示例中的类似代码,但我不能将内容放在父级的中间.

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.如何将旋转木马标题垂直居中？

解决方法:

.full-width {
    width: 100%;
}

.carousel-caption {
    position: absolute;
    top: 0;
    display: -webkit-Box;
    display: -moz-Box;
    display: -ms-flexBox;
    display: -webkit-flex;
    display: flex;
    -webkit-Box-align: center;
    -moz-Box-align: center;
    -ms-flex-align: center;
    -webkit-align-items: center;
    align-items: center;
    height: 100%;
}
