How to set vertical alignment in Bootstrap ?

  • Difficulty Level : Expert
  • Last Updated : 20 Aug, 2021

Vertical Alignment changes the alignment of elements vertically with the help of vertical-alignment utilities. The vertical-align utilities only affect inline(Present in one Line), inline-block(Present as blocks in one line), inline-table, and table cell(Elements in a cell of a table) elements. Vertical Alignment of div is one of the most basic requirements of a responsive web page. This can be achieved through CSS but the Bootstrap library has some classes specifically built for this purpose. In this article, we will learn the available classes & methods used for verticle-align in Bootstrap. Please refer to Vertical alignment in Bootstrap with Examples for other verticle-align classes.

Here, we will discuss 2 built-in classes:

  • Using class align-items-center
  • Using class d-flex with class align-items-center

Let’s understand both the classes through examples.

Method 1: Using class align-items-center

In Bootstrap 5, if we want to vertically align an <div> element in the center, we can do this by applying the class align-items-center on the containing element of that div.



 

Example:

HTML




<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1" />
  
    <link
      rel="stylesheet"
      href=
  
    <script src=
    </script>
    <script src=
    </script>
    <script src=
    </script>
  </head>
  
  <body>
    <div class="container">
      <div
        class="row align-items-center bg-success text-light"
        style="min-height: 100vh">
        <div class="col-md-12">
          <h1>GeeksforGeeks</h1>
        </div>
      </div>
    </div>
  </body>
</html>

Output:

Method 2: Using class d-flex with class align-items-center

In Bootstrap 5, if we want to vertically align an <div> element in the middle of a containing element, we can do this by applying the class align-items-center and d-flex on the containing element of that div. Here, the d-flex class has the same effect as that of the display: flex; property in CSS.

Example:

HTML




<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1"/>
  
    <link
      rel="stylesheet"
      href=
  
    <script src=
    </script>
    <script src=
    </script>
    <script src=
    </script>
  </head>
  
  <body>
    <div class="d-flex align-items-center" style="min-height: 100vh">
      <div class="box w-100 text-success">
        <h1>GeeksforGeeks</h1>
      </div>
    </div>
  </body>
</html>
