Common errors and fixes

Native checkbox style still appears

Keep `appearance: none` and verify browser compatibility defaults.

Check mark looks off-center

Adjust size and check thickness together for balanced geometry.

Low contrast in checked state

Re-test check and background colors against accessibility targets.

Hover/focus style missing in production

Add focus-visible and hover rules around generated base styles.

Snippet conflicts with global inputs

Scope selectors to component classes to avoid unintended overrides.

Security and privacy notes

Style generation runs locally in your browser.
Keep unreleased design token values inside private channels.
Review copied CSS before publishing shared component docs.

Step-by-step workflow

Start with a minimal input for CSS Checkbox Generator and verify baseline behavior first.
Make assumptions explicit: encoding, delimiter strategy, and timezone.
Change one variable at a time and compare output diffs.
Keep one verified output snapshot as a team reference.

Quality checklist before sharing output

Confirm CSS Checkbox Generator output is deterministic across repeated runs with identical input.
Check boundary inputs (empty values, long fields, invalid characters).
Remove sensitive data before sharing output externally.
Verify final rendering on both desktop and mobile viewports.
