如何在CSS中使脱节图像的大小相同？

Question

我想做什么

在同一帧中对齐各种尺寸和形状的图像。 （仅CSS）
随着浏览器大小的变化，图像大小也会成比例地变化。

当前状态

JSFiddle
目前，只有水平图像效果良好。
较小的图像变大，较大的图像变小并适合框架。

在Fiddle演示中可以看到，方形和垂直效果不佳。

如何对所有形状执行此操作？

代码

与JSFiddle完全相同。
建议您查看JSFiddle，因为显示可能有些奇怪。

/* swiper (doesn't matter) */
var swiperCnt = new Swiper('.swiperCnt', {
  direction: 'vertical',
  autoHeight: true,
  pagination: {
    el: '.swiper-pagination',
    type: 'bullets',
    clickable: 'true',
  },
  keyboard: {
    enabled: true,
  },
  mousewheel: {
    forceToAxis: true,
    invert: true,
  },
});

/* The orange "big square" is crushed by the "small vertical" below and is less visible. */
.swiper-slide {
  display: flex;
  align-items: center;
  padding: 1%;
}
.swiper-slide img {
  width: 100%;
}

.swiper-container {
  displey: flex;
  width: 400px;
  height: 300px;
}

p {
  white-space: pre-wrap;
}

Answer 1

设置图像的图像宽度和高度，并使用object-fit: contain;

.swiper-slide {
  box-sizing: border-box; // <-- needed to compensate for padding
  display: flex;
  align-items: center;
  padding: 1%;
  img {
    width: 100%;  // <-- set width
    height: 100%; // <-- set height
    object-fit: contain; // <-- makes sure image fits 100% x 100%x
  }
}
