使用"display: grid"使父级元素扩展到子元素的宽度。

Question

使用"display: grid"使父级元素扩展到子元素的宽度。

编辑：不确定这是否为重复问题？我不希望背景颜色超出容器的宽度，我希望容器会扩展到其display:grid子元素的大小。更新示例以更好地解释我的问题。

我正在构建一个表格，其中每行都是CSS网格。我这样做是为了利用每个单元格的minmax()，使整个表格在单元格无法再缩小时可滚动，同时允许表格在有更多空间时增长。

这个功能很好，除了行的样式只适用于容器的宽度之外。

请查看这个示例：

.container {
  width: 430px;
  background: grey;
  overflow-x: scroll;
}

.row {
  display: grid;
  grid-template-columns: minmax(200px, 1fr) minmax(200px, 1fr) minmax(200px, 1fr) minmax(100px, 1fr);
  background: red;
  height: 3rem;
  margin: 0.5rem;
}

.cell {
  border: 1px solid black;
}

Scroll to the right inside the box:
<div class="container">
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
</div>
Elements with the <code>.row</code> class should expand to fit all the cells.

有没有什么办法可以解决这个问题？如果需要的话，我可以添加额外的元素！

为什么不在每个单元格中使用红色背景，而不是整行？ - Αntonis Papadakis

每一行都应该有渐变背景和圆角边框，这是我的设计要求。如果可能的话，将样式设置为整个行会更容易。 - Amygdaloideum

如果您需要使用单元格宽度填充grid-template-columns，您可以尝试以下方法：

.row {
  display: grid;
  grid-template-columns: auto auto auto auto;
  background: red;
  height: 3rem;
}

每个单元格的宽度为200像素，只需添加：

.cell {
    min-width: 200px;
    border: 1px solid black;
}

将行的显示方式更改为 inline-grid 看起来会有所帮助：

.container {
  width: 430px;
  background: grey;
  overflow-x: scroll;
}

.row {
  display: inline-grid;
  grid-template-columns: minmax(200px, 1fr) minmax(200px, 1fr) minmax(200px, 1fr) minmax(100px, 1fr);
  background: red;
  height: 3rem;
}

.cell {
  border: 1px solid black;
}

Scroll to the right inside the box:
<div class="container">
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
</div>
The red background should cover the whole row.

为避免在宽容器和窄子元素处于一行的问题（如上述解决方案），您可以使用更复杂的解决方案，该方案使用父元素上的display: flex; flex-direction: column，并附加align-items: start，强制行元素具有完整的宽度（与默认值stretch相反，后者使行宽度不超过容器）。

.container {
  width: 430px;
  background: grey;
  overflow-x: scroll;
  display: flex;
  flex-direction: column;
  align-items: start;
}

.container.container-wide{
  width: 1000px;
}

.row {
  display: grid;
  grid-template-columns: minmax(200px, 1fr) minmax(200px, 1fr) minmax(200px, 1fr) minmax(100px, 1fr);
  background: red;
  height: 3rem;
}

.cell {
  border: 1px solid black;
}

Scroll to the right inside the box:
<div class="container">
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
</div>
Wide container:
<div class="container container-wide">
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
</div>
The red background should cover the whole row.

如果行宽大于所有列的宽度之和，为了使行可以延展至容器的全宽度，可以通过将Update 1中的display: flex替换为display: grid来调整解决方案，如下所示：

.container {
  width: 430px;
  background: grey;
  overflow-x: scroll;
  display: grid;
}

.container.container-wide{
  width: 1000px;
}

.row {
  display: grid;
  grid-template-columns: minmax(200px, 1fr) minmax(200px, 1fr) minmax(200px, 1fr) minmax(100px, 1fr);
  background: red;
  height: 3rem;
}

.cell {
  border: 1px solid black;
}

Scroll to the right inside the box:
<div class="container">
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
</div>
Wide container:
<div class="container container-wide">
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
  <div class="row">
    <span class="cell">cell 1</span>
    <span class="cell">cell 2</span>
    <span class="cell">cell 3</span>
    <span class="cell">cell 4</span>
  </div>
</div>
The red background should cover the whole row.
