How to Achieve Equal Height Columns with Pure CSS?

How to Create True Equal Height Columns Using Pure CSS

When working with multiple columns of varying content lengths, achieving equal heights without resorting to background images can be a common challenge. After extensive research, we have developed a unique CSS solution that effectively addresses this issue.

Solution

For a simplified approach that effectively distributes vertical space, consider using the following properties:

.parent {
  display: table;
}

.child {
  display: table-cell;
}

This method assigns a table-like structure to the parent container and its children, ensuring that they occupy equal vertical space.

Compatibility

It is important to note that this solution is not compatible with Internet Explorer 7. If support for IE7 is crucial, a more complex approach may be necessary.

Example

<div class="parent">
  <div class="child">Column 1</div>
  <div class="child">Column 2 with longer content</div>
  <div class="child">Column 3</div>
</div>

In this example, all three columns will have the same height, regardless of the content length of each column.
