html - Bootstrap 4 网格行 - 图像未垂直对齐

Question

我有一行图像由于某种原因没有垂直对齐。如果我使用所有相同的图像，它看起来不错，但如果我用尺寸略有不同的不同图像替换它就不起作用。下面是一个示例:

这是我的 HTML 代码..注意我正在使用一些自定义 CSS 进行叠加，不确定这是否会导致问题

<div className="container">

          <div className="row">

            <div className="col-xl-12 mx-auto mb-3">
              <h2 className="abouthead">Portfolio</h2>
            </div>
          </div>
          <div className="row">
            <div className="col-lg-4 col-md-12 mb-4">
              <div
                className="view overlay hm-black-strong"

Answer 1

您是否尝试过为图像指定高度？然后申请Object-Fit CSS属性(property)。

img {
  object-fit: cover;  
  width: 400px;
  height: 400px;  
}
