How to Vertically Center a Div within its Parent Div?

Centering a Div Vertically within a Parent Div

Vertically centering a div within its parent div can be achieved through various methods, without relying on specific element dimensions.

Table Layout (Classic Approach)

This method utilizes table layout and inline-block display properties.

<div class="container">
  <div class="inner">
    ...
  </div>
</div>

.container {
  display: table-cell;
  vertical-align: middle;
  height: 500px;
  width: 500px;
}

.inner {
  display: inline-block;
  width: 200px;
  height: 200px;
}

Transform (Modern Approach)

Transformations offer a simpler solution for vertical centering.

.container {
  position: relative;
  height: 500px;
  width: 500px;
}

.inner {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  width: 200px;
  height: 200px;
}

Flexbox (Preferred Modern Approach)

Flexbox provides the most straightforward method for centered alignment.

.container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 500px;
  width: 500px;
}

.inner {
  width: 200px;
  height: 200px;
}

Note:

• The table layout approach is well-supported but may impact performance.
• Transform and flexbox offer modern solutions with greater support and ease of use.
• These methods ensure vertical centering regardless of the dimensions or content of the inner div.
