javascript - 如何以正确的纵横比显示响应式 5 张扑克牌图像？

Question

我想显示 5 张扑克牌，并排放置，水平边距就像在扑克 table 上一样。我试过了，但无法显示:

我还希望它能够响应，即在调整大小时保持宽高比。

Answer 1

正如 Armedin 所说，您的 div 中没有任何内容。 Width 和 height 100% 不会做任何事情。

我建议您不要将图片作为背景，因为它不会改变 div 的尺寸。使用 img 标签和 display: inline; 作为卡片 div。

.card {
  width: 100%;
  height: 100%;
  background-size: cover;
  display:inline;

编辑:如果您不想使用 img，您可以将 img 设置为不可见，然后使用背景图片，因为 div 的尺寸仍然是img标签里面。这不是一个好的解决方案，但它会起作用。
