html - 使图像大小相同

Question

我希望主页上的所有图片大小相同。但是，当我添加照片时，有些照片的高度不同。我希望它们在不拉伸(stretch)的情况下都一样，而是通过填充和裁剪来实现。我该怎么做呢？谢谢!

img {
  overflow: hidden;
  max-width: 100%;
  height: auto;
  margin: 0 0 10px 0;
}

<div class="thirds clearfix">

  <!-- one-third -->
  <div class="one-third mobile-collapse">
    <a href="thetrainer.html">
      <img src="http://i66.tinypic.com/vnfcro.jpg" width="400px" height="400px">
    </a>

Answer 1

纯 CSS 解决方案将要求您添加放置图像作为该 div 的背景图像，具有 background-size: cover 样式。

所以你的 anchor 标签应该有这些样式:

background-image: url('link-to-image.png');
background-repeat: no-repeat;
background-size: cover;
background-position: center center;

请注意，您的 anchor 标记应具有高度和宽度以显示图像作为其背景。
