Everything you need to know

Visual Flexbox Layout Builder

The CSS Flexbox Generator lets you design flexible box layouts without writing code from scratch. Set container properties like direction, wrap, justify-content, align-items, align-content, and gap. Watch your layout update in the live preview as you adjust each property. The visual builder removes the guesswork and helps you understand how each flexbox property affects layout.

Per-Child Flex Properties

Click any child item in the preview to edit its individual flex properties: grow, shrink, basis, align-self, and order. This makes it easy to create asymmetric layouts where certain items stretch, shrink, or reorder independently of their siblings.

Live Preview & Instant Feedback

Every change you make is reflected instantly in the live preview panel. Add or remove child elements to test how your layout adapts. The colored boxes make it easy to identify each item and see how they flow within the container.

One-Click CSS Copy

The generated CSS is displayed in a code block you can copy with one click. The output includes both the container and any customized child styles, ready to paste into your stylesheet.
