CSS Flexbox Generator
Generate CSS Flexbox layout code with configurable direction, alignment, justification, wrapping, and gap properties.
Run tool
This CSS Flexbox generator creates custom layout styling declarations based on your chosen flex container properties. When building responsive web layouts, flexbox controls how child elements distribute space and align along the main and cross axes. Adjust the flex direction to arrange items horizontally in rows or vertically in columns. Set the justification property to distribute elements across the main axis with options like center, flex-start, or space-between. Configure cross-axis alignment to manage item placement vertically or stretch elements to fill available room. You can also specify wrapping behavior to let items move to new lines when container space runs low, and provide a numeric gap spacing value in pixels. After running the generator, the result panel displays CSS snippet declarations including display flex, flex-direction, justify-content, align-items, flex-wrap, and gap for your stylesheet.
Instructions
- Specify the flex direction such as row or column.
- Enter your desired justification along the main axis, such as center or space-between.
- Set the alignment along the cross axis, such as center or flex-start.
- Choose your wrap behavior, entering nowrap or wrap.
- Enter the numeric gap distance between child items in pixels.
- Generate the CSS rule and copy the resulting code block into your stylesheet.
Examples
- Centered navigation bar: Direction set to row, Justify set to space-between, Align set to center, Wrap set to nowrap, and Gap set to 16. Generates a horizontal container rule with 16px item spacing.
- Card grid layout: Direction set to row, Justify set to flex-start, Align set to stretch, Wrap set to wrap, and Gap set to 24. Generates a multi-line wrapping flex container rule with 24px item spacing.
FAQ
What default values does the Flexbox generator use?
When fields are left blank, the generator defaults to a row direction, center justification, center alignment, nowrap wrapping, and a gap of 10 pixels.
How is the gap spacing rendered in the generated CSS?
The numeric gap value you provide is formatted with a px unit suffix in the generated CSS gap property declaration.
Does this tool preview or render HTML elements?
This tool generates CSS code declarations for you to paste into your web project stylesheet rather than rendering an interactive preview.
Can I enter column layout properties?
Enter column or column-reverse into the direction field to stack flex items vertically instead of in horizontal rows.
