本文介绍了在使用 flex-flow 的 flex 容器中，更喜欢收缩而不是增长:row wrap的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

显示具有以下规格的不同尺寸图像和比例的图库:

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

  1. 图像之间没有空格(边距).
  2. 尽可能尊重原始比例.
  3. 被链接包围的图片.
  4. 非 JS 解决方案.
  5. 图像可能会被裁剪一点.
  6. 便携式解决方案.
  7. 显示的图像集是随机的.
  8. 图像必须从左到右显示(防止使用列).

我使用以下 flexbox 解决方案实现了这一点:

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;
}

该解决方案有效，但根据窗口的大小，有些图片放大太多，我希望每行有更多元素，即使这些项目需要缩小更多.

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.

这意味着，而不是:

我更喜欢更高密度的项目，以便图像永远不会被放大:

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

我寻找了在全局范围内增加每行元素数量的解决方案，以便图像不会被放大(或至少不会放大太多:例如:最大 10%).

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).

目前我发现的两个 hackish 解决方案是:

The two hackish solutions I have found so far are:

使用 zoom 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;
}

但该属性在 Chrome 中效果很好，而在 Firefox 中则不然.

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

使用 width/height 和 transform: scale 模拟 zoom 属性:

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;
}

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

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.

有没有其他解决方案，更面向 flexgrid 的，允许这种控制?我曾尝试使用 flex-grow: 0:它确实禁用了不断增长的项目，但随后到处都是图像周围的空白.

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.

推荐答案

我修改了你的开始尝试.

I modify your starting attempt.

主要思想是将img width: 100%;改为width: auto;并指定链接' <代码>高度.这将为我们提供带有间隙的图像.

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

为了消除间隙，我们可以添加链接display: flex; 和flex-direction: column;.差不多完成了.

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

最后一步是添加到链接max-width: 100%;，如果图像width更宽，它将防止ovelflow比小屏幕中的列.如果我们将链接的height设置得更高，我们可以在Temani Afif的第4张图片的第一个解决方案中看到这样的问题. Edited

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

查看代码片段.

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;
}
