How to use the CSS Flexbox Generator
1
Set up the tool
Adjust the controls for the output you need. Most utilities show a live preview.
2
Fine-tune the result
Use the generated code, measurement or artifact and iterate until it fits your context.
3
Copy or export
Copy the value or download the file. Nothing is persisted after you close the page.
What CSS Flexbox Generator is for
Set direction, wrapping, alignment, gap and item order, preview the result and copy the CSS plus markup for your container.
The CSS Flexbox Generator is part of the Utilities collection on ToolFlow. It is designed for one concrete job: configure flex layouts visually. Everything runs client-side, so you can use it with sensitive material without creating a copy on someone else's server.
Common use cases
- Prototype a toolbar
- Centre content
- Explain flex alignment
Good to know
- No account is required, and there is no usage limit on the browser tool.
- Processing happens locally. Files are read from disk and the result is written back to your downloads folder.
- Results are reproducible: the same input and options produce the same output, with no hidden server round-trip.
- If the tool needs a live data source, the page states it explicitly instead of silently failing.

The questions people ask before using this tool.
No. State lives in the page and disappears when you close it. Nothing is written to a server database.
