How it works

Design Inputs and Selections

The Flexbox Generator applies the controls and values shown in its workspace. Use the displayed units and options; outputs reflect those selections and any assumptions stated on the page.

Output and Preview

The workspace shows the design value, preview, or code provided by this tool. Review units and format before applying the result elsewhere.

Review in the Target Context

Check generated values in the component, stylesheet, asset, or interface where they will be used. A tool preview does not replace review at the target widths and states.

Example Scenarios

Use the controls or presets available in the Flexbox Generator to create alternatives, then compare them against the needs of the intended interface.

Apply the Flexbox Generator result in its target component, stylesheet, or design file and check it with the surrounding layout and theme.

Share the selected Flexbox Generator settings together with the resulting value or code so a teammate can reproduce the same design choice.
