Vertical Align Center in Bootstrap 4

Vertical Align Center in Bootstrap 4

Important! Vertical center is relative to the height of the parent

If the parent of the element you're trying to center has no defined
height, none of the vertical centering solutions will work!

Now, onto vertical centering...

Bootstrap 5 (Updated 2021)

Bootstrap 5 is still flexbox based so vertical centering works the same way as Bootstrap 4. For example, align-items-center, justify-content-center or auto margins can used on the flexbox parent (row or d-flex).

  • use align-items-center on a flexbox row parent (row or d-flex)
  • use justify-content-center on a flexbox column parent (d-flex flex-column)
  • use my-auto on a flexbox parent

Vertical Center in Bootstrap 5

Bootstrap 4

You can use the new flexbox & size utilities to make the container full-height and display: flex. These options don't require extra CSS (except that the height of the container (ie:html,body) must be 100%).

Option 1 align-self-center on flexbox child

<div class="container d-flex h-100">
    <div class="row justify-content-center align-self-center">
     I'm vertically centered
    </div>
</div>

Option 2 align-items-center on flexbox parent (.row is display:flex; flex-direction:row)

<div class="container h-100">
    <div class="row align-items-center h-100">
        <div class="col-6 mx-auto">
            <div class="jumbotron">
                I'm vertically centered
            </div>
        </div>
    </div>
</div>

Option 3 justify-content-center on flexbox parent (.card is display:flex;flex-direction:column)

<div class="container h-100">
    <div class="row align-items-center h-100">
        <div class="col-6 mx-auto">
            <div class="card h-100 border-primary justify-content-center">
                <div>
                    ...card content...
                </div>
            </div>
        </div>
    </div>

More on Bootstrap 4 Vertical Centering

Now that Bootstrap 4 offers flexbox and other utilities, there are many approaches to vertical
alignment. http://www.codeply.com/go/WG15ZWC4lf

1 - Vertical Center Using Auto Margins:

Another way to vertically center is to use my-auto. This will center the element within it's container. For example, h-100 makes the row full height, and my-auto will vertically center the col-sm-12 column.

<div class="row h-100">
    <div class="col-sm-12 my-auto">
        <div class="card card-block w-25">Card</div>
    </div>
</div>

Vertical Center Using Auto Margins Demo

my-auto represents margins on the vertical y-axis and is equivalent to:

margin-top: auto;
margin-bottom: auto;

2 - Vertical Center with Flexbox:

vertical center grid columns

Since Bootstrap 4 .row is now display:flex you can simply use align-self-center on any column to vertically center it...

       <div class="row">
           <div class="col-6 align-self-center">
                <div class="card card-block">
                 Center
                </div>
           </div>
           <div class="col-6">
                <div class="card card-inverse card-danger">
                    Taller
                </div>
          </div>
    </div>

or, use align-items-center on the entire .row to vertically center align all col-* in the row...

       <div class="row align-items-center">
           <div class="col-6">
                <div class="card card-block">
                 Center
                </div>
           </div>
           <div class="col-6">
                <div class="card card-inverse card-danger">
                    Taller
                </div>
          </div>
    </div>

3 - Vertical Center Using Display Utils:

Bootstrap 4 has display utils that can be used for display:table, display:table-cell, display:inline, etc.. These can be used with the vertical alignment utils to align inline, inline-block or table cell elements.

<div class="row h-50">
    <div class="col-sm-12 h-100 d-table">
        <div class="card card-block d-table-cell align-middle">
            I am centered vertically
        </div>
    </div>
</div>

Important! Did I mention height?

Remember vertical centering is relative to the height of the parent element. If you want to center on the entire page, in most cases, this should be your CSS...

body,html {
  height: 100%;
}

Or use min-height: 100vh (min-vh-100 in Bootstrap 4.1+) on the parent/container. If you want to center a child element inside the parent. The parent must have a defined height.

Bootstrap 5 (Updated 2021)

Bootstrap 5 is still flexbox based so vertical centering works the same way as it did in Bootstrap 4. For example, align-items-center (flex-direction: row) and justify-content-center (flex-direction: column) can used on the flexbox parent (row or d-flex).

Centering examples in Bootstrap 5

Vertical center (don't forget the parent must have a defined height!):

  • my-auto for centering inside flex (.d-flex) elements
  • my-auto can be used to center columns (.col-) inside row
  • align-items-center to center columns (col-*) inside row

Horizontal center:

  • text-center to center display:inline elements & column content
  • mx-auto for centering inside flex elements
  • mx-auto can be used to center columns (.col-) inside row
  • justify-content-center to center columns (col-*) inside row

Bootstrap 4.3+ (Update 2019)

There's no need for extra CSS. What's already included in Bootstrap will work. Make sure the container(s) of the form are full height. Bootstrap 4 now has a h-100 class for 100% height...

Vertical center:

<div class="container h-100">
  <div class="row h-100 justify-content-center align-items-center">
    <form class="col-12">
      <div class="form-group">
        <label for="formGroupExampleInput">Example label</label>
        <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input">
      </div>
      <div class="form-group">
        <label for="formGroupExampleInput2">Another label</label>
        <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input">
      </div>
    </form>   
  </div>
</div>

https://codeply.com/go/raCutAGHre

the height of the container with the item(s) to center should be 100%
(or whatever the desired height is relative to the centered item)

Note: When using height:100% (percentage height) on any element, the element takes in the height of it's container. In modern browsers vh units height:100vh; can be used instead of % to get the desired height.

Therefore, you can set html, body {height: 100%}, or use the new min-vh-100 class on container instead of h-100.

Horizontal center:

  • text-center to center display:inline elements & column content
  • mx-auto for centering inside flex elements
  • offset-* or mx-auto can be used to center columns (.col-)
  • justify-content-center to center columns (col-*) inside row

How to center div vertically in Bootstrap 4?

If you want to vertically center those elements set the height and width of html and body to 100%. Setting width & height to 100% makes an element take on the height of it's parent.

Next, set all the child elements accordingly. In bootstrap width: 100% is w-100 and height:100% is h-100. Also, bootstrap uses a 12 column layout so change your class from col-md-4 to col-md-6

Note: you could add w-100 and h-100 to html and body in your code for the same effect.

<style>
    html,body{
      width:100%;
      margin:0;
        height:100%;
    }
</style>

<div class="container w-100 h-100">
    <div class="row align-items-center h-100">
      <div class="col-md-6">
        <h1 class="alert alert-primary">Vertical</h1>
      </div>
      <div class="col-md-6">
        <h1 class="alert alert-success">Vertical</h1>
      </div>
    </div>
  </div>

Vertical align DIV & Text in Bootstrap 4

Basically, this question has already been answered.

Use flexbox and justify-content-center to make the box centered, and h-100 for height:100%...

<div class="container">
  <div class="row">
    <div class="col-4">
      <div class="box h-100 d-flex justify-content-center flex-column">
        <h6>Title 1</h6>
        <p>A small description</p>
      </div>
    </div>
    <div class="col-4">
      <div class="box h-100 d-flex justify-content-center flex-column">
        <h6>Title 2</h6>
        <p>A bigger description goes here</p>
      </div>
    </div>
    <div class="col-4">
      <div class="box h-100 d-flex justify-content-center flex-column">
        <h6>Title 3</h6>
        <p>A large description is placed here to make whatever changes we need.</p>
      </div>
    </div>
  </div>
</div>

Or, if you want to apply the same changes to .box instead of using the Bootstrap classes...

https://jsfiddle.net/g38e9Lfm/

.box {
  background-color: grey;
  padding: 15px;
  display: flex;
  flex-direction: column;
  justify-content: center;
  height: 100%;
}

Vertical alignment in Bootstrap 4

You can use the flex-xs-middle class like this..

Bootstrap 4 Alpha 5

<div class="container-fluid">
    <div class="row">
        <div class="col-xs-6">
            <div class="circle-medium backgrounds"></div>
        </div>
        <div class="col-xs-6 flex-xs-middle">
            <div class="name">Supplier</div>
        </div>
    </div>
    <div class="row">
        <div class="col-xs-6">
            <div class="circle-medium backgrounds"></div>
        </div>
         <div class="col-xs-6 flex-xs-middle">
            <div class="name">Supplier</div>
        </div>
    </div>
</div>

UPDATE for Bootstrap 4.0.0

Now that Bootstrap 4 is flexbox by default there are many different approaches to vertical alignment using: auto-margins, flexbox utils, or the display utils along with vertical align utils. At first "vertical align utils" seems obvious but these only work with inline and table display elements. Below are the Bootstrap 4 vertical centering options. Remember, vertical alignment is relative to parent height.

1 - Vertical Center Using Auto Margins:

Another way to vertically center is to use my-auto. This will center the element within it's container. For example, h-100 makes the row full height, and my-auto will vertically center the col-sm-12 column.

<div class="row h-100">
    <div class="col-sm-12 my-auto">
        <div class="card card-block w-25">Card</div>
    </div>
</div>

my-auto represents margins on the vertical y-axis and is equivalent to:

margin-top: auto;
margin-bottom: auto;

2 - Vertical Center with Flexbox:

vertical center grid columns

Since Bootstrap 4 .row is now display:flex you can simply use align-self-center on any column to vertically center it...

       <div class="row">
           <div class="col-6 align-self-center">
                <div class="card card-block">
                 Center
                </div>
           </div>
           <div class="col-6">
                <div class="card card-inverse card-danger">
                    Taller
                </div>
          </div>
    </div>

or, use align-items-center on the entire .row to vertically center align all col-* in the row...

       <div class="row align-items-center">
           <div class="col-6">
                <div class="card card-block">
                 Center
                </div>
           </div>
           <div class="col-6">
                <div class="card card-inverse card-danger">
                    Taller
                </div>
          </div>
    </div>

3 - Vertical Center Using Display Utils:

Bootstrap 4 has display utils that can be used for display:table, display:table-cell, display:inline, etc.. These can be used with the vertical alignment utils to align inline, inline-block or table cell elements.

<div class="row h-50">
    <div class="col-sm-12 h-100 d-table">
        <div class="card card-block d-table-cell align-middle">
            I am centered vertically
        </div>
    </div>
</div>
