是的。!我们可以，但与一些媒体查询和列的最大数目是预定义的。

这里我用了4列。检查我的代码:

.container { display: flex; display: -webkit-flex; display: -moz-flex; flex-flow: row wrap; -webkit-flex-flow: row wrap; -moz-flex-flow: row wrap; } .container .item { display: flex; display: -webkit-flex; display: -moz-flex; justify-content: center; -webkit-justify-content: center; -moz-justify-content: center; flex-basis: 25%; //max no of columns in %, 25% = 4 Columns } .container .item .item-child { width: 130px; height: 180px; background: red; margin: 10px; } @media (max-width: 360px) { .container .item { flex-basis: 100%; } } @media (min-width:360px) and (max-width: 520px) { .container .item { flex-basis: 50%; } } @media (min-width:520px) and (max-width: 680px) { .container .item { flex-basis: 33.33%; } } <div class="container"> <div class="item"> <div class="item-child">1</div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> <div class="item"> <div class="item-child"></div> </div> </div>

请注意 1)不需要创建子div。它可以是任何其他的标签，如'img' r任何你想要的。 2)如果你想要更多的列，调整媒体查询和最大数目。的列。

我可以用容器上的justify-content: space between来做

我为它做了一个SCSS mixin。

@mixin last-row-flexbox($num-columns, $width-items){

  $filled-space: $width-items * $num-columns;
  $margin: calc((100% - #{$filled-space}) / (#{$num-columns} - 1));

  $num-cols-1 : $num-columns - 1;

  &:nth-child(#{$num-columns}n+1):nth-last-child(-n+#{$num-cols-1}) ~ & {
    margin-left: $margin;
  }
  @for $i from 1 through $num-columns - 2 { 
    $index: $num-columns - $i;
    &:nth-child(#{$num-columns}n+#{$index}):last-child{
      margin-right: auto;
    }
  }
}

你只需要设置项目的宽度百分比和列数。

我希望这能帮助到你。

假设:

你想要4列网格布局与包装 项目的数量不一定是4的倍数

除了第1、5、9项以外，在每一项上都设置左距。如果左边的边距是10px，那么每行有30px的边距分布在4个项目中。项目宽度百分比计算方法如下:

100% / 4 - horizontal-border - horizontal-padding - left-margin * (4 - 1) / 4

这是一个体面的工作，涉及flexbox最后一行的问题。

.flex { display: flex; flex-direction: row; flex-wrap: wrap; margin: 1em 0 3em; background-color: peachpuff; } .item { margin-left: 10px; border: 1px solid; padding: 10px; width: calc(100% / 4 - 2px - 20px - 10px * (4 - 1) / 4); background-color: papayawhip; } .item:nth-child(4n + 1) { margin-left: 0; } .item:nth-child(n + 5) { margin-top: 10px; } <div class="flex"> <div class="item">1</div> <div class="item">2</div> <div class="item">3</div> <div class="item">4</div> </div> <div class="flex"> <div class="item">1</div> <div class="item">2</div> <div class="item">3</div> <div class="item">4</div> <div class="item">5</div> <div class="item">6</div> </div> <div class="flex"> <div class="item">1</div> <div class="item">2</div> <div class="item">3</div> <div class="item">4</div> <div class="item">5</div> <div class="item">6</div> <div class="item">7</div> <div class="item">8</div> <div class="item">9</div> </div>

这很老套，但对我来说很管用。我试图达到一致的间距/边距。

.grid {
  width: 1024px;
  display: flex;
  flex-flow: row wrap;
  padding: 32px;
  background-color: #ddd;  

  &:after {
    content: "";
    flex: auto;
    margin-left:-1%;
  }

  .item {
    flex: 1 0 24.25%;
    max-width: 24.25%;
    margin-bottom: 10px;
    text-align: center;
    background-color: #bbb;

    &:nth-child(4n+2),
    &:nth-child(4n+3),
    &:nth-child(4n+4) {
      margin-left: 1%;
    }

    &:nth-child(4n+1):nth-last-child(-n+4),
      &:nth-child(4n+1):nth-last-child(-n+4) ~ .item {
        margin-bottom: 0;
    }    

  }
}

这里有一些解决方案，人们建议编写精确的布局css类，使用伪元素伪造最后一项，使用非flexbox方法等。

一个大问题是邻居之间的间隙(大小写对齐的按钮包装到多行)。在这种情况下，你不希望物品相互接触，就需要有空隙。我只是想添加一个适当的解决方案，尊重差距，并适用于任何数量的项目。它也是基于假的最后一个元素的想法，但更普遍。有关详细信息，请参阅代码片段注释。
