CSS网格自动适合最大内容 [英] CSS Grid auto fit with max-content

问题描述

我有4栏.第1列和第4列的实际内容为150像素，第2列为250像素，第3列为370像素.我想在浏览器宽度改变时换行.当我减小浏览器的宽度时，我希望每列在包装前缩小到其最小宽度.因此，我认为第4列在低于150px宽度后将以100％的宽度下降到下一行.

I have 4 columns. The actual content for columns 1 and 4 is 150px, column 2 is 250px and column 3 is 370px. I want to wrap the columns when the browser width changes. When I decrease the width of the browser, I want each column to shrink down to their lowest width before wrapping. So I imagine the 4th column would fall to the next row with a 100% width after it fell below 150px width.

这是我认为应该完成的窍门:

Here's what I thought should've done the trick:

repeat(auto-fit, minmax(max-content, 1fr))

有没有一种方法可以在不传递最大内容"为固定宽度的情况下实现这一目标?

Is there a way to achieve this without passing a fixed width where 'max-content' is?

这是我使用媒体查询和固定宽度的解决方案

Here's my solution using media queries and hard widths

这是我在上面的小提琴中使用的html/css:

Here's the html/css I used in the fiddle above:

.container {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(370px, 1fr));
  grid-gap: 8px;
}

@media (max-width: 799px) {
  .container {
      grid-template-columns: minmax(max-content, 1fr);
  }
}

@media (min-width: 800px) {
  .container .p2,
  .container .p3 {
    grid-column: auto / span 2;
  }
}

.container > div {
  background-color: gray;
  text-align: center;
}

<div class="container">
  <div class="p1">
    <img src="https://via.placeholder.com/150x150">
  </div>
  <div class="p2">
    <img src="https://via.placeholder.com/250x150">
  </div>
  <div class="p3">
    <img src="https://via.placeholder.com/370x150">
  </div>
  <div class="p4">
    <img src="https://via.placeholder.com/150x150">
  </div>
</div>

推荐答案

在处理网格时，我有一个类似的问题:

I had a similar question when playing around with grid:

grid-template-columns: repeat(auto-fit, minmax(max-content, 1fr))

如果我们看一下文档，我们会发现minmax命令是有效的: https://developer.mozilla.org/zh-CN/docs/Web/CSS/minmax

If we take a look at the documentation we can see that minmax command is valid: https://developer.mozilla.org/en-US/docs/Web/CSS/minmax

但是在有关csswg的重复文档中，它陈述了一个简单的规则，不允许所有这些事情发生； https://drafts.c​​sswg.org/css-grid/#funcdef-repeat

But in a repeat documentation on csswg, it states one simple rule that disallows all of this from happening; https://drafts.csswg.org/css-grid/#funcdef-repeat

repeat()语法的通用形式大约是

The generic form of the repeat() syntax is, approximately,

repeat( [ <positive-integer> | auto-fill | auto-fit ] , <track-list> )

第一个参数指定重复次数.第二 参数是一个跟踪列表，重复该次数.

The first argument specifies the number of repetitions. The second argument is a track list, which is repeated that number of times.

但是，有一些限制:

• repeat()表示法不能嵌套.

• The repeat() notation can’t be nested.

自动重复(自动填充或自动调整)不能与 固有尺寸或灵活尺寸.

Automatic repetitions (auto-fill or auto-fit) cannot be combined with intrinsic or flexible sizes.

什么是固有尺寸或灵活尺寸?

Whats an intrinsic or flexible sizes ?

• 内部大小调整函数(min-content，max-content，auto，fit-content()).

• An intrinsic sizing function (min-content, max-content, auto, fit-content()).

因此该命令将无法在网格中使用，因为每列/行的大小都会不同，并且无法进行换行.参见下面的图片.

So the command wont work in grid because each column/row will be different sizes and wrapping cannot take place. See bellow picture as example.

此行为应改为使用flex-box来执行.

This behavior should be executed using flex-box instead.
