Why this tool is useful
Create a branded checkbox without losing the native checked input, keyboard access or a clear focus indicator for people navigating without a mouse.
Design & CSS · runs locally
Accessible CSS Checkbox Generator
Build a custom checkbox with a visible checked state, keyboard focus ring and bounded size, radius and color controls, then copy the complete CSS locally.
Ready. Your working data stays in this browser.
How it works
The browser clamps dimensions to practical ranges, accepts only six-digit colors and renders a checked preview from static DOM nodes before returning reusable CSS.
Practical example
Set a 24-pixel control, 6-pixel corners and a violet focus ring to match a compact settings form while retaining a visible keyboard outline.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
