Local processing inputs

Local Worker: 10s startup, 1s processing. 32KiB per field, 1MiB complete result. Editing or clearing cancels work and stale output. Generated HTML/CSS is not mounted; remote image preview requires a separate action.

Preview and code

Edit fields and build a preview; complete code can be copied or downloaded.

Model and scope

Generate 1–100 named pixel breakpoints. Mobile-first order is ascending and desktop-first descending; names must be unique ASCII CSS identifiers. Choose viewport or inline-size/size container queries. Add-ons are independent media blocks. Presets are declared widths, not device detection; common widths are a local selection. Custom preserves the original four widths. No URL/storage persistence.
