使用 flex-flow: row wrap 在 flex 容器中收缩而不是增长

Question

显示具有以下规格的不同尺寸和比例的图片库：

图像之间没有空白（边距）。
尽可能尊重原始比例
图像被 link.
非 JS 解决方案。
图片可能被裁剪了一点。
便携式解决方案。
显示的图像集是随机的。
图像必须从左到右显示（防止使用列）。

我通过以下 flexbox 解决方案实现了这一目标：

section {
  display: flex;
  flex-flow: row wrap;
  justify-content: center;
}
section a {
  flex: auto;
}
section img {
  height: 100%;
  width: 100%;
  object-fit: cover;
}

该解决方案有效，但根据 window 的大小，一些图片放大太多，我希望每行有更多元素，即使项目需要缩小更多。

这意味着代替：

我希望项目的密度更高，这样图像就不会被放大：

我寻找解决方案来全局增加每行元素的数量，这样图像就不会被放大（或者至少不会放大太多：例如：最大 10%）。

目前我找到的两个 hackish 解决方案是：

解决方案 1

使用缩放属性:

section {
  display: flex;
  flex-flow: row wrap;
  justify-content: center;
  zoom: 50%;
}
section a {
  flex: auto;
}
section img {
  height: 100%;
  width: 100%;
  object-fit: cover;
}

但是属性在 Chrome 中很好用，但在 Firefox 中不行。

解决方案 2

用宽度/高度和[=模拟缩放属性 64=]变换：缩放:

section {
  display: flex;
  flex-flow: row wrap;
  justify-content: center;
  width: 200% !important;
  height: 200% !important;
  transform-origin: 0 0;
  transform: scale(0.5);
  float: left;
  margin-right: -100000px;
  margin-bottom: -100000px;

section a {
  flex: auto;
}
section img {
  height: 100%;

该解决方案到目前为止有效，但需要一些 hack，并且远非优雅，现在会对页面的其他元素产生影响。

是否有任何其他解决方案，更面向 flexgrid，允许这种控制？我试过使用 flex-grow: 0: 它确实禁用了增长的项目，但是到处都是图像周围的空白。

Answer 1

解决此问题的一种方法是将 line-height: 0 添加到 a 并将 height 值设置为 px 值。

section {
  display: flex;
  flex-flow: row wrap;
  justify-content: center;
}
section a {
  flex: auto;
  line-height: 0;
}
section img {
  height: 300px;
  width: 100%;
  object-fit: cover;
}

Answer 2

这里有一个想法，您可以考虑高度来控制行的大小，主要技巧是依靠 min-width:100% 为您的图像填充 space。

基本上，a 将定义高度，图像将遵循该高度并计算 auto 宽度以保持比例。图像的宽度将定义 link 的宽度，然后 link 将增长以填充 space（在其中创建 space）。最后，min-width:100%你会让图像填充space里面创建的link.

section {
  display: flex;
  flex-flow: row wrap;
  justify-content: center;
}

section a {
  flex: auto;
  height: 100px;
}

section img {
  height: 100%;
  width: auto; /* we need auto to keep the ratio based on the height */
  min-width: 100%; /* we expand the image to fill the gaps */
  max-width:100%;
  object-fit: cover;
}

如果您考虑 vw 高度单位，您将拥有一个静态网格，该网格将在保持相同整体结构的同时进行缩放：

section {
  display: flex;
  flex-flow: row wrap;
  justify-content: center;
}

section a {
  flex: auto;
  height: 8vw;
}

section img {

Answer 3

我修改你的起始尝试。

主要思想是将imgwidth: 100%;改为width: auto;并指定链接'height。这将为我们提供有间隙的图像。

要消除间隙，我们可以添加链接 display: flex; 和 flex-direction: column;。快完成了。

最后一步 是添加到链接max-width: 100%;，如果图像width 比小屏幕中的列宽，它将防止ovelflow。 ~~如果我们放置更高 height 的链接，我们可以在 Temani Afif 的第一个解决方案第 4 张图片中看到这样的问题。~~ 已编辑

查看代码段。

section {
  display: flex;
  flex-flow: row wrap;
  justify-content: center;
}

section a {
  flex: auto;
  display: flex;
  flex-direction: column;
  height: 166px;
  max-width: 100%;
}

section img {
  height: 100%;
  width: auto;
  object-fit: cover;
}
