css – 如何让物品伸展以填充宽度？

.container {
  display: grid;
  grid-template-columns: repeat(auto-fill,100px);
  grid-gap: 3px;
  border: 1px solid green;
}

.item {
  border: 1px solid red;
  height: 50px;
}

<div class="container">
  <div class="item"></div>

如何将红色物品盒拉伸一点,以便它们填满绿色容器盒的整个宽度？

它们应该都是相同的宽度,并且大于100px.

最后一行应该像现在一样左对齐.

解决方法

您只需要将一个分数单位添加到grid-template-columns规则中.

grid-template-columns: repeat(auto-fill,minmax(100px,1fr));

此规则会创建适合容器的列数.

每列的最小宽度为100px.

最大宽度为1fr,这意味着该列将消耗该行上的任何可用空间.

现在正在使用容器中的所有水平空间.

.container {
  display: grid;
  grid-template-columns: repeat(auto-fill,1fr));
  grid-auto-rows: 50px;
  grid-gap: 3px;
  border: 1px solid green;
}

.item {
  border: 1px solid red;
}

<div class="container">
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
</div>
