页面容器未与页面居中对齐居中问题

Question

我试图使页面容器居中，同时保持内容的左对齐。

我最初是在flexbox上尝试此操作，但是遇到了问题，所以有些复杂。

主包装容器居中，但内部包装容器未居中

flexbox是否可能？为什么在我告诉容器居中对齐的情况下，容器为何不居中？

主包装容器居中，但内部包装容器未居中

从width:33%中删除.item，并给.stockListItems一个justify-content: space-between。这样会将.item div均匀拉伸到.pageWrapper容器的末尾。然后给.pageWrapper一个width: 90%：

body {
  margin: 0px;
  padding: 0px;
}

.center {
  text-align: center;
}

.pageWrapper {
  max-width: 800px;
  display: block;
  margin: 0 auto;
  padding-top: 100px;
  width: 90%;
}

.pageWrapper .country {
  font-size: 16px;
}

.pageWrapper .stockistItems {
  display: flex;
  border-bottom: 1px solid #eaeaea;
  padding: 25px 0px;
  margin-bottom: 20px;
  /*justify-content: center;*/
  justify-content: space-between;
}

.pageWrapper .stockistItems .item {
  display: flex;
  flex-direction: column;
  /*width: 33%;*/
}
