What is CSS Grid and Flexbox?

CSS Grid is a two-dimensional layout system for creating complex grid-based layouts. Flexbox is a one-dimensional layout system for arranging items in rows or columns. Both are modern CSS layout methods that make responsive design easier.

How do I create a Grid layout?

Select 'Grid' layout type, add blocks to your layout, configure grid properties (columns, rows, gaps, alignment), and see the layout update in real-time. Export the CSS code when you're done.

How do I create a Flexbox layout?

Select 'Flexbox' layout type, add blocks, configure flex properties (direction, wrap, justify-content, align-items, gap), and see the layout update in real-time. Export the CSS code when you're done.

Can I customize block properties?

Yes! Each block can be customized with content, background color, and size. You can add, remove, and reorder blocks to create your desired layout structure.

Can I export the CSS code?

Yes! Click 'Copy CSS' to copy the generated CSS code to your clipboard. Use it directly in your stylesheets or projects. The code includes all the properties you've configured.

Is the layout generator free?

Yes, completely free! No registration, no limits, no hidden fees. All layout generation happens in your browser - we never see or store your layouts.

CSS Grid vs Flexbox

CSS Grid is a two-dimensional layout system, meaning it can handle both columns and rows. It's perfect for creating complex layouts with precise control over both axes. Grid excels at creating page layouts, card grids, and any design that needs alignment in two dimensions.

Flexbox is a one-dimensional layout method for laying out items in rows or columns. It's ideal for distributing space and aligning content within a container. Flexbox is perfect for navigation bars, centering content, and creating flexible components.

Our visual layout generator lets you experiment with both Grid and Flexbox. Add blocks, adjust properties, and see your layout update in real-time. Perfect for learning, prototyping, and generating production-ready CSS.

CSS Grid Properties

grid-template-columns

Defines the line names and track sizing functions of the grid columns.

grid-template-columns: repeat(3, 1fr);
grid-template-columns: 1fr 2fr 1fr;
grid-template-columns: 200px auto 300px;

grid-template-rows

Defines the line names and track sizing functions of the grid rows.

grid-template-rows: auto;
grid-template-rows: 100px 200px;
grid-template-rows: repeat(2, 1fr);

gap

Sets the gaps (gutters) between rows and columns. Shorthand for row-gap and column-gap.

Flexbox Properties

flex-direction

Establishes the main-axis, defining the direction flex items are placed in the flex container.

flex-direction: row;        /* default */
flex-direction: column;
flex-direction: row-reverse;
flex-direction: column-reverse;

justify-content

Defines how the browser distributes space between and around content items along the main-axis.

justify-content: flex-start;
justify-content: center;
justify-content: space-between;
justify-content: space-around;

align-items

Controls the alignment of items on the cross-axis (perpendicular to the main-axis).

Common Use Cases

📐 Grid: Page Layouts

Use CSS Grid for overall page structure - header, sidebar, main content, footer. Grid's two-dimensional nature makes it perfect for complex layouts.

📱 Grid: Card Grids

Create responsive card grids that automatically adjust to available space. Use repeat() and auto-fit/auto-fill for flexible, responsive designs.

🎯 Flexbox: Navigation

Flexbox is ideal for navigation bars. Use justify-content to space items, align-items to center vertically, and flex-wrap for responsive behavior.

🎨 Flexbox: Centering

The easiest way to center content both horizontally and vertically. Use justify-content: center and align-items: center on a flex container.

🔄 Combined Approach

Use Grid for the overall page layout and Flexbox for components within grid areas. This combines the strengths of both layout methods.

📦 Flexbox: Form Layouts

Flexbox makes form layouts simple. Use flex-direction: column for stacked inputs, and flex properties on form elements for flexible sizing.

Frequently Asked Questions

When should I use Grid vs Flexbox?

Use Grid for two-dimensional layouts (rows and columns) like page layouts, card grids, and complex designs. Use Flexbox for one-dimensional layouts (row OR column) like navigation bars, centering content, and flexible components.

Can I use Grid and Flexbox together?

Absolutely! Use Grid for the overall page structure and Flexbox for components within grid areas. This is a common and recommended approach that combines the strengths of both layout methods.

What does repeat() do in Grid?

repeat(3, 1fr) creates 3 columns, each taking 1 fraction of available space.repeat(auto-fit, minmax(200px, 1fr)) creates as many columns as fit, each at least 200px wide.

How do I make a responsive grid?

Use repeat(auto-fit, minmax(200px, 1fr)) orrepeat(auto-fill, minmax(200px, 1fr)). This automatically adjusts the number of columns based on available space.

What's the difference between justify-content and align-items in Flexbox?

justify-content aligns items along the main-axis (horizontal in row, vertical in column).align-items aligns items along the cross-axis (vertical in row, horizontal in column).

Can I save my layouts?

You can export the CSS code to a file, which you can then use in your projects. All processing happens in your browser, so your layouts are never stored on our servers.
