CSS网格动态列自动匹配列之间的间隙

Question

我正在尝试youtube.com自适应网格布局。我可以实现使用CSS网格。但是，如果总卡片数量非常少，例如2，卡片的宽度增加，以适应整排。我可以通过设置最大宽度或宽度来避免这种情况，但是，当我更改浏览器窗口的宽度时，卡片上的间隙会发生变化。

如何在不增加卡间距的情况下设置最大宽度？

.grid-layout {
  padding: 0;
  margin: 0;
  list-style: none;
  border: 1px solid silver;
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(5rem, 1fr) );
}

.card {
  background: grey;
  height: 4rem;
  /* Uncommenting below line sets width but gap between card too high*/
  /* max-width: 7rem; */
  padding: 1px;
  margin: 0.5rem;
  line-height: 4rem;
  color: white;
  font-weight: bold;
  font-size: 2rem;
  text-align: center;
}

<section class="grid-layout">
    <div class="card">0</div>
    <div class="card">1</div>

Answer 1

使用值为百分比的grid-gap：

​

.grid-layout {
  list-style: none;
  border: 1px solid silver;
  display: grid;
  grid-gap: 20%;
  grid-template-columns: 1fr 1fr;
}

.card {
  background: grey;
  height: 8rem;
  padding: 1px;
  line-height: 8rem;
  color: white;
  font-weight: bold;
  font-size: 2rem;
  text-align: center;
}

<section class="grid-layout">
    <div class="card">0</div>
    <div class="card">1</div>
    <!-- <div class="card">2</div>
    <div class="card">3</div>
    <div class="card">4</div>
    <div class="card">5</div>
    <div class="card">6</div>
    <div class="card">7</div>
    <div class="card">8</div>
    <div class="card">9</div>
    <div class="card">10</div>
    <div class="card">11</div>
    <div class="card">12</div>
    <div class="card">13</div>
    <div class="card">14</div>
    <div class="card">15</div>
    <div class="card">16</div>
    <div class="card">17</div>
    <div class="card">18</div>
    <div class="card">19</div> -->

这是你想要的吗？

Answer 2

自动填充按照我的预期工作，而不是在列未包装时自动安装。

​

.grid-layout {
  padding: 0;
  margin: 0;
  list-style: none;
  border: 1px solid silver;
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(5rem, 1fr) );
}

.card {
  background: grey;
  height: 4rem;
  max-width: 7rem;
  padding: 1px;
  margin: 0.5rem;
  line-height: 4rem;
  color: white;
  font-weight: bold;
  font-size: 2rem;
  text-align: center;
}

<section class="grid-layout">
    <div class="card">0</div>
    <div class="card">1</div>
    <!-- <div class="card">2</div>
    <div class="card">3</div>
    <div class="card">4</div>
    <div class="card">5</div>
    <div class="card">6</div>
    <div class="card">7</div>
    <div class="card">8</div>
    <div class="card">9</div>
    <div class="card">10</div>
    <div class="card">11</div>
    <div class="card">12</div>
    <div class="card">13</div>
    <div class="card">14</div>
    <div class="card">15</div>
    <div class="card">16</div>
    <div class="card">17</div>
    <div class="card">18</div>
    <div class="card">19</div> -->
