html - 以可延展的列数居中

Question

我正在尝试列出一系列相同大小的元素。我希望这些元素在左右(垂直居中？)上以均匀的间距显示，并且彼此之间的间距均匀。最大的问题是列表需要能够适应屏幕大小的变化和元素数量的变化。因此，每行的宽度和元素需要根据需要更新。最下面的行也应该与上面的行对齐。

这是迄今为止我能得到的最接近的。

HTML

<div class="outer">
  <div class="inner">
  </div>
</div>
... repeated as any times as there are blocks.
<div class="outer">
  <div class="inner">
  </div>
</div>

CSS

body {
  text-align: justify;
  margin:0;
  width: auto; 
}

.outer {
  background:blue;
  width: 100px;
  height: 90px;
  display: inline-block;
  text-align: center;
}

.inner {
  background:red;
  width: 90px; 
  height: 90px;
  display: inline-block;
  text-align: center;
}

听起来像是 flexbox 的工作。其中一个对你有用吗？ https://codepen.io/anon/pen/VEpbjv
