Answer 1

您可以将 margin: 0 auto 设置为 .wrapper 中的 p 元素:

.main {
  color: white;
  background: blue;
  position: relative;
  height: 300px;
  padding: 10px;
}
.wrapper {
  display: flex;
  justify-content: center;
  flex-direction: column;
  text-align: center;
  position: absolute;
  width: calc(100% - 20px);
  height: calc(100% - 20px);
}
.wrapper p {
  color: #000;
  background: lightgrey;
  margin: 0 auto;/*add margin 0 auto*/
}

<div class="main">
  <div class="wrapper">
    <p>Please press Enter to continue installation</p>
  </div>
  <p>Welcome to Windows 95</p>
</div>
