In this article, we would like to show you how in CSS, center an element vertically using flexbox when elements are ordered in the row direction (by default flex uses flex-direction: row; so it is not needed to add it).

Quick solution:

.container {
    display: flex;
    align-items: center;
}

Practical example

In this example, we're using a flexbox with the align-items property to vertically center the item inside the flex container.

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
<head>
  <style>

    .container {
        border-radius: 10px;
        background: #3085d6;
        width: 200px;
        height: 200px;
        box-shadow: 5px 5px 15px gray;
      
        display: flex;        /*  <----- required   */
        align-items: center;  /*  <----- required   */
    }

    .item {
        border: 1px solid black;
        border-radius: 5px;
        background: #ffc353;
        width: 50px;
        height: 50px;
    }

  </style>
</head>
<body>
  <div class="container">
    <div class="item"></div>
  </div>
</body>
</html>

Multiple items

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
<head>
  <style>

    .container {
        border-radius: 10px;
        background: #3085d6;
        width: 200px;
        height: 200px;
        box-shadow: 5px 5px 15px gray;
      
        display: flex;        /*  <----- required   */
        align-items: center;  /*  <----- required   */
    }

    .item {
        margin: 2px;
        border: 1px solid black;
        border-radius: 5px;
        background: #ffc353;
        width: 50px;
        height: 50px;
    }

  </style>
</head>
<body>
  <div class="container">
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
