html - 使用自动放置包裹 CSS 网格

Question

我正在尝试构建一个包含类似卡片的元素的网格。每种类型的单元格(标题、图片、文本、按钮等)在每一行中的高度应相等，由最大单元格的内容决定，如下面的代码片段所示。

现在我试图限制列数，并让卡片环绕，就像我在基于 flexbox 的解决方案中使用 flex-wrap: wrap; 一样。列数应通过媒体查询确定。如果不使用尚未支持的 subgrids 是否可行？ ？

此外，使用子网格的解决方案会是什么样子？我猜它会降级为当前浏览器中高度不等的单元格？

.grid {
  display: grid;
  grid-template-rows: repeat(4, auto);
  grid-gap: 10px;
  grid-auto-flow: column;
  grid-auto-columns: auto;
}

<div class="grid">

  <h2 class="a">Header 1</h2>
  <img class="b" src="https://placekitten.com/400/100" />
  <p class="c">text
  </p>
  <button class="d">Button</button>

  <h2 class="a">Header 2 is longer and may span multiple lines</h2>
  <img class="b" src="https://placekitten.com/400/100" />
  <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis et cursus ligula. Maecenas non pharetra dui, eu tincidunt mi. Vivamus vitae luctus risus. Etiam vehicula sem est.
  </p>
  <button class="d">Button</button>


  <h2 class="a">Header 1</h2>
  <img class="b" src="https://placekitten.com/400/100" />
  <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis et cursus ligula. Maecenas non pharetra dui, eu tincidunt mi. Vivamus vitae luctus risus. Etiam vehicula sem est, non ultricies lectus placerat eget.
  </p>
  <button class="d">Button</button>

  <h2 class="a">Header 1</h2>
  <img class="b" src="https://placekitten.com/400/100" />
  <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis et cursus ligula. Maecenas non pharetra dui, eu tincidunt mi. Vivamus vitae luctus risus. Etiam vehicula sem est, non ultricies lectus placerat eget. Suspendisse pulvinar arcu massa, quis
    varius velit facilisis tincidunt. Proin sed cursus orci.
  </p>
  <button class="d">Button</button>

  <h2 class="a">Header 1</h2>
  <img class="b" src="https://placekitten.com/400/100" />
  <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit.
  </p>
  <button class="d">Button</button>
</div>

Answer 1

这是我们需要子网格的情况的一个很好的例子 - 对齐网格表亲在诸如这个问题的布局中是必不可少的。

直到浏览器实现建议的 Subgrids 的 2 级规范，我们只能包装元素中的每一列，然后使用外部网格容器包装它。

以下是 Editor's Draft 的摘录CSS 网格布局模块级别 2:

2.  Subgrids

A grid item can itself be a grid container by giving it display: grid; in this case the layout of its contents will be independent of the layout of the grid it participates in.

In some cases it might be necessary for the contents of multiple grid items to align to each other. A grid container that is itself a grid item can defer the definition of its rows and columns to its parent grid container, making it a subgrid. In this case, the grid items of the subgrid participate in sizing the grid of the parent grid container, allowing the contents of both grids to align.

可以找到讨论此问题的好读物 here .

这是一个使用嵌套网格容器的模型(子网格可以看起来像这样，但没有违反非等同表亲规则)- 请参见下面的演示:

.wrapper {
  display: grid;
  grid-gap: 10px;
  grid-template-columns: repeat(auto-fill, minmax(400px, 1fr));
}

.grid {
  display: grid;
  grid-template-rows: repeat(4, 1fr);
  justify-items: flex-start;
  border: 1px solid #07c;
}

img {
  width: 100%;
}

button {
  align-self: center;
  justify-self: center;
}

p {
  padding: 0 10px;
}

<div class="wrapper">

  <div class="grid">
    <h2 class="a">Header 1</h2>
    <img class="b" src="https://placekitten.com/400/100" />
    <p class="c">text
    </p>
    <button class="d">Button</button>
  </div>

  <div class="grid">
    <h2 class="a">Header 2 is longer and may span multiple lines</h2>
    <img class="b" src="https://placekitten.com/400/100" />
    <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis et cursus ligula. Maecenas non pharetra dui, eu tincidunt mi. Vivamus vitae luctus risus. Etiam vehicula sem est.
    </p>
    <button class="d">Button</button>
  </div>

  <div class="grid">
    <h2 class="a">Header 1</h2>
    <img class="b" src="https://placekitten.com/400/100" />
    <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis et cursus ligula. Maecenas non pharetra dui, eu tincidunt mi. Vivamus vitae luctus risus. Etiam vehicula sem est, non ultricies lectus placerat eget.
    </p>
    <button class="d">Button</button>
  </div>

  <div class="grid">
    <h2 class="a">Header 1</h2>
    <img class="b" src="https://placekitten.com/400/100" />
    <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis et cursus ligula. Maecenas non pharetra dui, eu tincidunt mi. Vivamus vitae luctus risus. Etiam vehicula sem est, non ultricies lectus placerat eget. Suspendisse pulvinar arcu massa, quis
      varius velit facilisis tincidunt. Proin sed cursus orci.
    </p>
    <button class="d">Button</button>
  </div>

  <div class="grid">
    <h2 class="a">Header 1</h2>
    <img class="b" src="https://placekitten.com/400/100" />
    <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    </p>
    <button class="d">Button</button>
  </div>

</div>

一个可能的定义是:

.wrapper {
  display: grid; /* outer grid */
  /* sets a wrapping grid container with items of width around 400px */
  grid-template-columns: repeat(auto-fill, minmax(400px, 1fr)); 
}

.grid {
  grid-row: span 4; /* span 4 rows */
  display: grid;
  /* magic is here */
  grid-template-rows: subgrid; /* create a sub-grid with the 4 parent grid rows */
}
