Complete Flexbox Guide

CSS Flexbox is a one-dimensional layout model designed for laying out items in rows or columns. It provides powerful alignment and distribution capabilities that simplify complex layouts that were previously difficult with floats and positioning.

Flexbox is ideal for navigation bars, card layouts, centering content, equal-height columns, and responsive designs where items need to adapt to available space.

What is CSS Flexbox?

CSS Flexbox (Flexible Box Layout) is a one-dimensional layout model that provides efficient ways to distribute space and align content within a container, even when item sizes are unknown.

What is flex-direction?

flex-direction defines the main axis direction. 'row' lays items left to right, 'column' top to bottom, and the reverse variants flip these directions.

What does justify-content do?

justify-content aligns items along the main axis. Options include flex-start, flex-end, center, space-between, space-around, and space-evenly.

What does align-items do?

align-items aligns items along the cross axis (perpendicular to main axis). Common values are stretch, center, flex-start, flex-end, and baseline.

What is flex-wrap?

flex-wrap controls whether flex items wrap to new lines. 'nowrap' keeps all items on one line, 'wrap' allows wrapping, and 'wrap-reverse' wraps in reverse order.

What is the gap property?

The gap property sets the spacing between flex items. It is a shorthand for row-gap and column-gap and is supported in all modern browsers.

When should I use Flexbox vs Grid?

Use Flexbox for one-dimensional layouts (rows or columns). Use CSS Grid for two-dimensional layouts where you need control over both rows and columns simultaneously.

Is Flexbox supported in all browsers?

Yes, Flexbox has excellent browser support across all modern browsers including Chrome, Firefox, Safari, Edge, and Opera.

Is this tool free?

Yes, completely free with no signup required. Generate unlimited flexbox layouts with live preview.

Can I nest flex containers?

Yes, flex items can also be flex containers themselves, allowing for complex nested layouts.
