What is the CSS Flexbox Generator?

Think of the CSS Flexbox Generator as the Swiss Army Knife for modern web layouts. In the past, aligning elements in the center or creating equal-height columns was a nightmare for developers. Flexbox solved this, and our generator makes that power visual and intuitive.

This tool allows you to act as a layout architect, arranging "flex items" within a container with absolute precision. Whether you are building a responsive navigation bar, a centered landing page hero, or a complex grid of cards, you can experiment with alignment and spacing properties in real-time and see the code update instantly.

How to Use the CSS Flexbox Generator?

  1. 1
    Configure the Container:

    Start by adjusting the Flex Direction (Rows/Columns), Justify Content, and Align Items. This determines how all items behave collectively inside the parent box.

  2. 2
    Manage Flex Items:
    Add & Individualize:Add or remove items using the controls. Click on an individual item to adjust its Flex Grow, Shrink, or Align Self properties for unique positioning.
  3. 3
    Visualize Dimensions:

    Customize container width, height, and background colors. Toggle Gap sliders to see how spacing works between items without using margins.

  4. 4
    Copy the Code:

    Switch to the Generated CSS tab to inspect the clean code. Copy it with one click and paste it directly into your project's stylesheet.

Key Flexbox Features Explained

Flex Direction:Defines the main axis (Row/Column) along which items are laid out.
Justify Content:Controls alignment on the main axis (e.g., Space-Between, Center, Flex-End).
Align Items:Defines the default behavior for how flex items are laid out along the cross axis.
Flex Wrap:Determines if items should stay on one line or wrap onto multiple lines if space runs out.
Real-time CSS:Generates clean HTML and CSS structure instantly with syntax highlighting for developers.
Responsive Ready:Test how your layout handles different container sizes and wrapping behaviors for mobile devices.

Pro Tips

Main vs Cross

If your direction is row, the main axis is horizontal. If it's column, the main axis is vertical.

Flex-Basis

Think of flex-basis as the "ideal" size of an item before the remaining space is distributed.

Flex-Grow

An item with flex-grow: 2 will take up twice as much available space as an item with flex-grow: 1.
