Getting Started

The Flexbox Generator is an intuitive tool for creating and visualizing CSS flexbox layouts. Whether you're building a navigation bar, card grid, or complex multi-column layouts, this tool helps you experiment with flexbox properties in real-time.

Quick Start Steps:

  1. Use the Interactive Preview panel to see your layout in real-time
  2. Adjust Container Properties to control the overall layout behavior
  3. Click on individual items to modify their specific properties
  4. Apply Preset Layouts for common flexbox patterns
  5. Copy or export your code in CSS, HTML, Tailwind, or React format

Tip: The preview panel is interactive - click on any item to select it and modify its individual properties like flex-grow, align-self, and order.

Interactive Visual Preview

The Visual Preview panel provides a real-time representation of your flexbox layout. You can interact with the preview to select items and see how different flexbox properties affect the layout.

Live Updates

All changes to flexbox properties are reflected immediately in the preview panel, allowing you to see the effects in real-time.

Item Selection

Click on any item in the preview to select it. Selected items are highlighted and their individual properties can be modified.

Dynamic Items

Add or remove flex items using the +/- buttons. You can have between 1 and 12 items in the preview.

Preview Controls:

  • Add Item: Click the + button to add a new flex item
  • Remove Item: Click the - button to remove the last item
  • Select Item: Click on any item to edit its individual properties
  • Reset: Click Reset to restore default settings

Container Properties

Container properties control the overall layout behavior of the flex container. These properties affect how flex items are arranged within the container.

Display

Controls whether the container is a block-level or inline-level flex container. Options: flex or inline-flex.

Flex Direction

Sets the direction of flex items within the container. Options: row, row-reverse, column, column-reverse.

Flex Wrap

Controls whether flex items wrap to new lines. Options: nowrap, wrap, wrap-reverse.

Justify Content

Aligns flex items along the main axis. Options: flex-start, flex-end, center, space-between, space-around, space-evenly.

Align Items

Aligns flex items along the cross axis. Options: stretch, flex-start, flex-end, center, baseline.

Align Content

Aligns flex lines when there is extra space in the cross axis. Only applies when flex-wrap: wrap is set.

Gap

Sets the space between flex items. Range: 0px to 100px in 4px increments.

Item Properties

Item properties control the behavior of individual flex items. To modify item properties, first click on an item in the preview panel to select it. The selected item is highlighted with a blue border.

Note: Item properties only apply to the currently selected item. Unselected items use default values.

Flex Grow

Controls how much a flex item will grow relative to other items. Value: 0 to 5. Default is 0 (item won't grow).

Flex Shrink

Controls how much a flex item will shrink relative to other items. Value: 0 to 5. Default is 1 (item can shrink).

Flex Basis

Sets the initial size of a flex item before remaining space is distributed. Accepts values like auto, 100px, 50%, etc.

Align Self

Overrides the container's align-items property for the selected item. Options: auto, flex-start, flex-end, center, baseline, stretch.

Order

Controls the order in which flex items appear. Value: -10 to 10. Default is 0. Items with lower values appear first.

Preset Layouts

The tool includes several preset layouts that demonstrate common flexbox patterns. Click any preset to instantly apply its configuration.

Navigation Bar

Horizontal navigation layout with space-between alignment. Perfect for headers with logo on left and links on right.

Card Grid

Responsive card layout with wrapping. Items flow to new lines while maintaining consistent spacing.

Centered Content

Perfect center alignment using column direction. Ideal for modals, hero sections, or centered content blocks.

Sidebar Layout

Fixed sidebar with flexible content area. Common pattern for dashboard layouts and documentation sites.

Holy Grail Layout

Classic header-content-footer layout using column direction. Traditional web page structure.

Tip: Presets are great starting points. After applying a preset, you can customize any property to match your specific needs.

Code Output

The tool generates production-ready code in multiple formats. Switch to the "Generated Code" tab to view and copy the code.

CSS Output

Pure CSS with container and item properties. Ready to paste into your stylesheet.

.container {
  display: flex;
  flex-direction: row;
  justify-content: space-between;
  align-items: center;
  gap: 16px;
}

HTML Output

Complete HTML structure with inline styles for quick prototyping or standalone examples.

Tailwind CSS Output

Tailwind CSS classes equivalent to your flexbox configuration. Great for modern React projects.

className="flex flex-row justify-between items-center gap-4"

React Component Output

Ready-to-use React component with inline styles or CSS modules. Includes TypeScript support.

Code Copying:

Each code tab has a copy button that copies the code to your clipboard. A toast notification confirms when the code has been copied.

Export Options

In addition to copying code snippets, you can export your complete layout as an HTML file for offline use or sharing.

Export Actions:

  • Copy CSS: Copies the generated CSS code to clipboard
  • Export HTML: Downloads a complete HTML file with embedded styles
  • Reset: Restores all settings to their default values

Note: The exported HTML file includes all necessary styles and creates a standalone flexbox layout that works offline.

Common Use Cases

Navigation Headers

Use the Navigation Bar preset or configure justify-content: space-between for logo-menu layouts.

Card Layouts

Use flex-wrap: wrap with card grids. Items wrap naturally on smaller screens.

Centering Content

Use column direction with justify-content: center and align-items: center for perfect centering.

Sidebar Layouts

Use row direction with flex-grow on the content area and fixed width for the sidebar.

Holy Grail Layout

Use column direction with header, main, and footer sections. Classic page structure.

Reordering Items

Use the order property on individual items to change their visual order without affecting HTML structure.
