Flexbox: center horizontally and vertically-第2页回答

How to center div horizontally, and vertically within the container using flexbox. In below example, I want each number below each other (in rows), which are centered horizontally.

.flex-container {
  padding: 0;
  margin: 0;
  list-style: none;
  display: flex;
  align-items: center;
  justify-content: center;
}
row {
  width: 100%;
}
.flex-item {
  background: tomato;
  padding: 5px;
  width: 200px;
  height: 150px;
  margin: 10px;
  line-height: 150px;
  color: white;
  font-weight: bold;
  font-size: 3em;
  text-align: center;
}

<div class="flex-container">
  <div class="row">
    <span class="flex-item">1</span>
  </div>
  <div class="row">
    <span class="flex-item">2</span>
  </div>
  <div class="row">
    <span class="flex-item">3</span>
  </div>
  <div class="row">
    <span class="flex-item">4</span>
  </div>
</div>

  <div class="PADDER-CENTER">
    <div contentEditable="true">Edit this text...</div>

If you need to center a text in a link this will do the trick:

div {
  display: flex;

  width: 200px;
  height: 80px;
  background-color: yellow;
}

a {
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center; /* only important for multiple lines */

  padding: 0 20px;
  background-color: silver;
  border: 2px solid blue;
}

<div>
  <a href="#">text</a>
  <a href="#">text with two lines</a>
</div>

margin: auto works perfect with flexbox. It centralize vertically and horizontally.

html, body {
  height: 100%;
  max-height: 100%;
}

.flex-container {
  display: flex;
    
  height: 100%;
  background-color: green;
}

.container {
  display: flex;
  margin: auto;
}

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JS</title>
</head>
<body>
  <div class="flex-container">
    <div class="container">
      <div class="row">
        <span class="flex-item">1</span>
      </div>
      <div class="row">
        <span class="flex-item">2</span>
      </div>
      <div class="row">
        <span class="flex-item">3</span>
      </div>
     <div class="row">
        <span class="flex-item">4</span>
    </div>
  </div>  
</div>
</body>
</html>
