html – 如何创建具有相等宽度列的居中CSS网格？

2023年12月20日 207次阅读

我想要一个菜单​​栏,其中所有菜单项具有相同的宽度(与最宽的菜单项一样宽).菜单项的数量可以变化.如果有额外的空间,菜单应该在其容器中居中.

如果项目不适合一行,则项目可能会换行另一行,但它们仍应具有相同的宽度.像这样的东西：

|    [   short   ] [loooooooong] [  between  ]    |
|    [  wrapped  ]                                |

我可以用CSS做到这一点吗？

我尝试使用display：grid,但失败了：

.container { 
  border: 1px solid black;
  display:inline-block;
}

.menu { 
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(50px, -webkit-max-content));
  grid-template-columns: repeat(auto-fit, minmax(50px, max-content));
  justify-content: center;
  grid-gap: 10px;
  
  background: #eee;
}

.item { 
  border: 1px solid #aaa;
  background: yellow;
  white-space: nowrap;
}
<div class="container">
  <h2>Two items</h2>
  
  <p>
    These should have equal widths (as wide as the widest one is) and be centered within the container.
  </p>
  
  <div class="menu">
    <div class="item">Short</div>
    <div class="item">Looooooooooong</div>
  </div>
  
  <p>
    They are centered all right, but don't have equal widths.
  </p>

  <h2>Three items</h2>
  
  <p>
    These three should also have same width with each other.
  </p>
  
  <div class="menu">
    <div class="item">First item</div>
    <div class="item">Second item</div>
    <div class="item">Third</div>
  </div>

  <p>
    They are centered all right, but don't have equal widths.
  </p>
  
  <h2>So many items that they won't fit on one line</h2>

  <p>
    These should also have equal widths, but they should wrap to the next row. I don't care whether the second row is centered as long as the items are aligned with the row above.
  </p>
  
  <div class="menu">
    <div class="item">First item</div>
    <div class="item">Second item</div>
    <div class="item">Third item, a longer one</div>
    <div class="item">Fourth item</div>
    <div class="item">Fifth item</div>
    <div class="item">Sixth item</div>
    <div class="item">Seventh item</div>
    <div class="item">Eight item</div>
    <div class="item">Ninth item</div>
    <div class="item">Tenth item</div>
    <div class="item">Item number 11</div>
    <div class="item">Item number 12</div>
    <div class="item">Item number 13</div>
    <div class="item">Item number 14</div>
    <div class="item">Item number 15</div>
    <div class="item">Item number 16</div>
    <div class="item">Item number 17</div>
    <div class="item">Item number 18</div>
    <div class="item">Item number 19</div>
    <div class="item">Item number 20</div>
    <div class="item">Item number 21</div>
    <div class="item">Item number 22</div>
    <div class="item">Item number 23</div>
  </div>
  <p>
    They have equal widths, but the width is the min width given in minmax and the content doesn't fit within the item.
  </p>
</div>

问题Centered table-like layout with columns of equal widths using CSS?是类似的,但是按钮的数量是固定的,没有包装.

它不需要显示：grid.

最佳答案 你有没有尝试1fr 1fr 1fr(每个都代表整个的1个单一部分,在这种情况下,列)

其他人正在推荐flexbox,但css-grid理论上可以做任何flexbox但可以获得二维的额外好处(相比之下只有1 w / flexbox).此外,css-grid集成在浏览器级别,因此不依赖于任何框架.
