我有一个简单的flex-box布局的容器,如:

.grid {
  display: flex;
  flex-flow: row wrap;
  justify-content: space-between;
}

现在我想让最后一行中的项目与其他项目对齐。justify-content:之间的空间;应使用,因为网格的宽度和高度是可以调节的。

目前看来

在这里,我希望右下角的项目在“中间一列”中。最简单的方法是什么?下面是一个展示这种行为的小jsfiddle。

.exposegrid { display: flex; flex-flow: row wrap; justify-content: space-between; } .exposetab { width: 100px; height: 66px; background-color: rgba(255, 255, 255, 0.2); border: 1px solid rgba(0, 0, 0, 0.4); border-radius: 5px; box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2); margin-bottom: 10px; } <div class="exposegrid"> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> <div class="exposetab"></div> </div>

你不能。Flexbox不是一个网格系统。它没有实现您所要求的功能的语言结构,至少在使用justify-content: space between时是这样。使用Flexbox最接近的方法是使用列方向,这需要设置显式的高度:

http://cssdeck.com/labs/pvsn6t4z(注:不包括前缀)

ul {
  display: flex;
  flex-flow: column wrap;
  align-content: space-between;
  height: 4em;
}

然而,只使用列会更简单,它有更好的支撑,不需要设置特定的高度:

ul {
  columns: 15em;
}

你还可以这样做:

.exposegrid:last-child {
  margin-right: auto;
}

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。

如果你想要一个在项目之间有一些空间的网格,并且项目开始时没有任何初始空间,那么这个简单的解决方案是有效的:

.grid {
    display: flex;
    flex-flow: row wrap;
    margin: 0 -5px; // remove the inital 5px space
    width: auto;
}
.grid__item {
    width: 25%;
    padding: 0 5px; // should be same as the negative margin above.
}

如果你想要初始的5px空间,那么只需删除负边距:)简单。

被接受的答案,虽然很好,但它导致第二行元素之间没有空格。

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;
    }    

  }
}

我修改了Dan Andreasson给出的示例,在元素上使用右边框来创建一个伪gutter。然后,您可以使用第n -child删除所需列网格计数的最后一个子节点上的边框。这里是一个演示https://codepen.io/JacobLett/pen/mdVoroM
