如何在引导程序的 3 列中均匀对齐我的内容？

Question

如下图所示，我的内容不是均匀对齐的。有没有办法在 Bootstrap 中均匀对齐我的内容？例如，我希望我的图像在每一列中都对齐。我不介意段落和图像之间是否有一些空白。

Answer 1

为当前.row 下方的图像使用单独的.row div，并在其中放置与当前用于文本和图像的相同类型的列/div 具有相同的类.

Answer 2

好的，这是我在使用基于浮点的网格系统时遇到的一个问题。

以下是您如何在 Bootstrap 中解决当前网格系统问题的草图：http://jsbin.com/yolewusuza/

@media screen and (min-width: 992px) {
  .content {
    position: absolute;
    top: 0;
    left: 15px;
    right: 15px;
    bottom: 0;
  }
  .col-sm-4:after {
    padding-bottom: 170%;
    content: '';
    display: block;
  }
  .content .image {
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
  }
}

调整列新创建的伪元素上的 padding-bottom 以满足您的需要。理想情况下，您需要限制摘录长度。

Answer 3

使用框架的.thumbnail 组件（带有.caption），您可以完成@Johannes 的建议，如下所示，包括将您自己的高度添加到.caption，如下所示。确保根据需要调整身高。

.caption{
  min-height: 300px;
  height: 300px;
}
