css - 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:

  1. No blanks (margins) between images.
  2. Respecting the original ratio as much as possible.
  3. Images surrounded by a link.
  4. Non-JS solution.
  5. Images could be cropped a bit.
  6. Portable solution.
  7. Set of images displayed is random.
  8. 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;
}

I modify your starting attempt.

Main idea is to change img width: 100%; to width: auto; and specify links' height. This will give us images with gaps.

To remove the gaps we could add to links display: flex; and flex-direction: column;. Almost done.

Last step is to add to links max-width: 100%;, it will protect from ovelflow if image width will be wider than column in small screen. Such problem we could see in Temani Afif's first solution with 4th image, if we put higher height of links. Edited

Look into snippet.

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;
}
