What Is Flexbox Generator?

The Flexbox Generator builds a flex container from dropdowns for direction, wrap, justify-content, align-items, and align-content, plus gap, padding, and an adjustable item count. The preview uses the same values as the generated CSS.

Who Uses the Flexbox Generator?

Developers use it to settle a layout before writing it, especially for centring a single element, distributing items evenly, or making a row that wraps on small screens.

How to Use the Flexbox Generator

  1. Choose a flex direction and wrap setting.
  2. Pick how items are justified and aligned.
  3. Adjust the gap, padding, and number of preview items.
  4. Copy the container rule and the optional item margin.

Why Choose Our Flexbox Generator?

  • Every flexbox property in one panel
  • Live preview with a realistic number of items
  • Omits defaults to keep the CSS tidy
