About CSS Flexbox Generator

CSS Flexbox is a one-dimensional layout system that makes it easy to align and distribute space among items in a container. This generator lets you visually explore all the key container properties and copy the generated CSS directly into your project.

Key Properties

  • flex-direction - Sets the main axis direction (row or column).
  • flex-wrap - Controls whether items wrap onto multiple lines.
  • justify-content - Aligns items along the main axis.
  • align-items - Aligns items along the cross axis within each line.
  • align-content - Aligns multiple lines along the cross axis.
  • gap - Sets the spacing between flex items.

How to Use

  1. Set the flex-direction (row or column) and justify-content using the dropdown controls.
  2. Set align-items and flex-wrap as needed.
  3. Add or remove child items using the + Add Item button.
  4. The live preview shows how items lay out with the current settings.
  5. Click Copy CSS to copy the container and item styles.

How It Works

The tool applies the selected flexbox property values directly to the preview container as inline styles. The generated CSS output includes the container's display, direction, wrap, justification, and alignment properties ready to paste into your stylesheet.

Example

Center a card horizontally and vertically on the page: set justify-content: center, align-items: center, min-height: 100vh on the parent. Copy the CSS and apply it to your layout container.

FAQ

Flexbox is supported in all modern browsers including Chrome, Firefox, Safari, and Edge. It has had broad support since 2015 and is safe to use in all current projects.
Flexbox is best for one-dimensional layouts - laying out items in a single row or column. CSS Grid is better for two-dimensional layouts where you need control over both rows and columns simultaneously.
