Create, Visualize, and Export Professional Flexbox Layouts
A powerful tool for creating CSS flexbox layouts with an interactive visual editor, real-time preview, and multi-format code export. Perfect for building responsive layouts without memorizing flexbox syntax.
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.
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.
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.
All changes to flexbox properties are reflected immediately in the preview panel, allowing you to see the effects in real-time.
Click on any item in the preview to select it. Selected items are highlighted and their individual properties can be modified.
Add or remove flex items using the +/- buttons. You can have between 1 and 12 items in the preview.
Container properties control the overall layout behavior of the flex container. These properties affect how flex items are arranged within the container.
Controls whether the container is a block-level or inline-level flex container. Options: flex or inline-flex.
Sets the direction of flex items within the container. Options: row, row-reverse, column, column-reverse.
Controls whether flex items wrap to new lines. Options: nowrap, wrap, wrap-reverse.
Aligns flex items along the main axis. Options: flex-start, flex-end, center, space-between, space-around, space-evenly.
Aligns flex items along the cross axis. Options: stretch, flex-start, flex-end, center, baseline.
Aligns flex lines when there is extra space in the cross axis. Only applies when flex-wrap: wrap is set.
Sets the space between flex items. Range: 0px to 100px in 4px increments.
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.
Controls how much a flex item will grow relative to other items. Value: 0 to 5. Default is 0 (item won't grow).
Controls how much a flex item will shrink relative to other items. Value: 0 to 5. Default is 1 (item can shrink).
Sets the initial size of a flex item before remaining space is distributed. Accepts values like auto, 100px, 50%, etc.
Overrides the container's align-items property for the selected item. Options: auto, flex-start, flex-end, center, baseline, stretch.
Controls the order in which flex items appear. Value: -10 to 10. Default is 0. Items with lower values appear first.
The tool includes several preset layouts that demonstrate common flexbox patterns. Click any preset to instantly apply its configuration.
Horizontal navigation layout with space-between alignment. Perfect for headers with logo on left and links on right.
Responsive card layout with wrapping. Items flow to new lines while maintaining consistent spacing.
Perfect center alignment using column direction. Ideal for modals, hero sections, or centered content blocks.
Fixed sidebar with flexible content area. Common pattern for dashboard layouts and documentation sites.
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.
The tool generates production-ready code in multiple formats. Switch to the "Generated Code" tab to view and copy the code.
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;
}Complete HTML structure with inline styles for quick prototyping or standalone examples.
Tailwind CSS classes equivalent to your flexbox configuration. Great for modern React projects.
className="flex flex-row justify-between items-center gap-4"Ready-to-use React component with inline styles or CSS modules. Includes TypeScript support.
Each code tab has a copy button that copies the code to your clipboard. A toast notification confirms when the code has been copied.
In addition to copying code snippets, you can export your complete layout as an HTML file for offline use or sharing.
Note: The exported HTML file includes all necessary styles and creates a standalone flexbox layout that works offline.
Use the Navigation Bar preset or configure justify-content: space-between for logo-menu layouts.
Use flex-wrap: wrap with card grids. Items wrap naturally on smaller screens.
Use column direction with justify-content: center and align-items: center for perfect centering.
Use row direction with flex-grow on the content area and fixed width for the sidebar.
Use column direction with header, main, and footer sections. Classic page structure.
Use the order property on individual items to change their visual order without affecting HTML structure.
