HTML- Center a div element vertically

In this tutorial, we are going to learn about how to center a div element vertically in HTML with the help of examples.

Consider, we have the following div element in our HMTL:

<div class="container">
  <h1>Hello, User</h1>
</div>

To center a div vertically in HTML, add the display:flex and align-items: center to the div CSS class.

“align-items: center” centers the div vertically.

Here is an example:

<div class="container">
  <h1>Hello, User</h1>
</div>

CSS:

.container{
    display: flex;
    align-items: center;
    height:100vh;
}

or we can add the inline styles to div using the style attribute in HTML.

<div style="display:flex; align-items:center; height:100vh;">
  <h1>Hello, User</h1>
</div>

Centering the div vertically using absolute position

We can use the absolute positioning in html to center the div vertically.

Here is an example:

<div class="container">
     <h1>Hello, User</h1>
</div>

.container{
   position:absolute;
   top:50%;
   transform:translateY(-50%);
}

1. Here we added position:absolute to the div element, so the element breaks out from the normal document flow and positioned to its relative parent (eg: body or parent element).

2. The top:50% moves the element 50% down from its position.

3. The translateY(-50%) moves the element 50% up from it’s position.
