How Can Flexbox Achieve Equal Height Columns in CSS?

Flxexbox Solution for Equal Height Columns in CSS

In your code, you are attempting to use a table with percentages for equal height columns. However, this approach may encounter challenges. As a viable alternative, consider leveraging Flexbox.

HTML:

<ul>
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li>
  <li>6</li>
</ul>

CSS:

ul {
  display: flex;
}

With this simple Flexbox implementation, you can ensure that every list item maintains the same height, regardless of its content.

How It Works:

• The display: flex property on the
  element declares it as a flex container.
  • By default, a flex container arranges its child elements (flex items) horizontally.
  • The default align-items: stretch property instructs flex items to occupy the full height of the container, resulting in equal height columns.

  Notes:

  • Flexbox equal height columns only apply to sibling elements.
  • Setting a specific height on a flex item overrides the equal height functionality.
  • Equal height columns work only within a single line.
  • To disable equal height behavior in Flexbox, use align-items: flex-start or align-items: flex-end.

  Browser Support:

  Flexbox is widely supported across modern browsers, including Chrome, Firefox, Safari, and Edge. For older browsers like IE < 10, consider using vendor prefixes to ensure compatibility. Tools like Autoprefixer can automate this process.
