以前的帖子：

.container {
  background-color: #2196f3;
}

.container > .wrapper {
  padding: 3rem 0;
}

/* optional */

span {
  display: block;
 }
<div class="container">
  <div class="wrapper">
    <span class="item-1">
      Item 1
    </span>
    <span class="item-2">
      Item 2
    </span>
  </div>
</div>

有大约一千种方法可以使某物垂直居中，您可以使用flex-box，也可以使用position: absolute，top: 50%和transform: translateY(-50%)中的一种混合方法。 / p>

,

在您的css文件中，进行以下更改：

.PcYqm {
  box-sizing: border-box;
  padding-bottom: 5px;
  padding-top: 5px; // added this
  margin: 10px;
  background: red;
}

.eZmlQJ {
  box-sizing: border-box;
  padding-top: 5px;
  padding-bottom: 5px; // added this
  margin: 10px;
  background: green;
}

接下来在HTML标签中同时为“选择文件”添加此CSS：

<label for="uploadFileExport" style="margin-top: .5rem" ... 
<label for="uploadFileSubmit" style="margin-top: .5rem" ...

除了此内联CSS外，您还可以创建一个类，但可能无法正常工作，因为标签正在从Bootstrap标签继承CSS。
