输入和按钮在子div内居中

如何解决输入和按钮在子div内居中

我有一个父div，其中有3个子div。我需要每个子div占用屏幕的三分之一，并且每个div内的所有元素（文本，按钮和输入）都必须始终位于子div的中心以进行响应。

我可以做出这样的排序：每个子div占据屏幕的三分之一，但是元素没有响应，并且将自己潜入子div的两列中，如下图所示：

以下是使用的代码：

input,select,textarea {
  width: 100%;
  padding: 6px;
  border: 1px solid #ccc;
  border-radius: 5px;
}

label {
  padding: 12px 12px 12px 0;
  display: inline-block;
}

.Order_Create_Ship_Stock>div {
  width: 30%;
  margin: 5px;
  padding: auto;
  display: inline-table;
  border: solid;
}

.Order_Create,.Order_Ship,.Order_Store {
  border-radius: 5px;
  background-color: #f2f2f2;
  padding: 10px;
  display: table-cell;
}

#SubmitCreateOrder,#SubmitShipOrder,#SubmitStoreOrder {
  cursor: pointer;
  display: flex;
  flex-direction: column;
}

当我在工作时，我可以使用flexbox（flex-direction：column）以某种方式使按钮保留在一列中，但是这种方法不适用于输入和文本区域...

因此，我想请一些帮助，以使这些子div中的所有元素仅保留在一列中。

在此先感谢任何愿意花时间帮助我的人。

解决方法

对于按钮，增加边距：自动，居中放置任何孩子都可以完成这项工作，如果您认为将其设为完整按钮有用，我会在第一个按钮中添加一个选项。

还可以使容器响应，您可以将父级设置为弹性框。然后使用flex：1设置所有子项，并使用媒体查询将其设置为列。

刚发现错误，我只需要添加到标签而不是输入，请选择以下内容：

display: flex;
flex-direction: column;
