Prefer shrinking over growing in a flex container with flex-flow: row wrap

Question

Prefer shrinking over growing in a flex container with flex-flow: row wrap

Displaying an image gallery of different sized images and ratio with the following specs:

No blanks (margins) between images.
Respecting the original ratio as much as possible.
Images surrounded by a link.
Non-JS solution.
Images could be cropped a bit.
Portable solution.
Set of images displayed is random.
Images must be displayed from left to right (prevents using columns).

I achieved that with the following flexbox solution:

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

The solution works, but depending on the size of the window, some pictures are enlarged way too much, I would prefer more elements per row, even if the items needs to be shrinked more.

This means that instead of:

I would prefer a higher density of items so that images never gets enlarged:

I looked for solutions to increase globally the number of elements per row so that images does not get enlarged (or at least not too much: for example: 10% max).

The two hackish solutions I have found so far are:

Solution 1

Using the zoom property:

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;
}

But that property works great in Chrome, not in Firefox.

Solution 2

Emulating the zoom property with width/height and transform: scale:

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%;
  width: 100%;
  object-fit: cover;
}

That solution worked so far, but requires a few hacks, and is far from being elegant and now will have impacts with the other elements of the page.

Is there any other solution, more flexgrid-oriented that permits that kind of control? I have tried using flex-grow: 0: it, indeed, disables growing items, but then there are blanks around images everywhere.

我修改了你的起始尝试。

主要思想是更改img width: 100%;为width: auto;并指定 links' height。这将为我们提供有间隙的图像。

为了消除间隙，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，如果图像比小屏幕中的列宽，max-width: 100%;它将防止 ovelflow 。~~如果我们放置更高的链接，我们可以在 Temani Afif 的第一个解决方案（第四张图片）中看到这样的问题。~~已编辑width~~height~~

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;
