How Can I Create Equal Height Columns with Pure CSS?

Achieving Equal Height Columns with CSS

In the realm of web development, the quest for visually appealing layouts often leads to the desire for equal height columns. Achieving this effect using pure CSS can be a challenge, prompting many developers to turn to solutions like background images. However, there exists a simpler and more efficient method.

The Vertical Table Approach

To achieve equal height columns without resorting to background images, the "vertical table" approach proves to be both effective and cross-browser compatible. This technique involves assigning the parent div the display: table property and its children the display: table-cell property.

Implementation

.parent {
  display: table;
}
.child {
  display: table-cell;
}

By applying these CSS rules, the parent div is transformed into a table, while its child elements become table cells. Each cell thus fills the vertical space of the table, resulting in columns of equal height.

Compatibility

This solution enjoys compatibility with all modern browsers. However, it's important to note that it does not work in Internet Explorer 7. If support for IE7 is essential, a more comprehensive approach may be necessary.

Conclusion

The "vertical table" method provides a straightforward and efficient way to achieve equal height columns using pure CSS. By utilizing this technique, developers can create visually consistent layouts without the reliance on background images or complex hacks.
