How to Use the CSS Flexbox Generator

1 Select flex-direction (row, column, row-reverse, column-reverse).
2 Choose justify-content for main-axis alignment.
3 Set align-items for cross-axis alignment.
4 Configure flex-wrap and gap size.
5 Adjust the number of items to see how the layout responds.
6 Copy the generated CSS code.

CSS Flexbox is a one-dimensional layout model that distributes space along a single axis. The flex container's main axis is set by flex-direction (row = horizontal, column = vertical). justify-content controls spacing along the main axis, while align-items controls the cross axis. The gap property adds consistent spacing between items without margins.

Flexbox is ideal for navigation bars, card layouts, centering content, and distributing items evenly. Unlike CSS Grid (which is two-dimensional), Flexbox works best for layouts that flow in one direction. The wrap property allows items to flow to the next line when they don't fit, making it responsive by default.
