Guides
Build a ready-to-paste <input type="number"> field — set the name, label, placeholder, and numeric constraints (required, min, max, step, default value), then copy the HTML straight into your page.
Runs entirely in your browser: no AI call, no credits, no network round-trip. The output updates instantly as you type.
How to use it
- Set the Name (used for the
name/idattributes) and Label. - Adjust Settings — required, min/max, step, default value — to match your form's validation needs.
- Copy or download the generated HTML.
Why is there no live preview?
The output is real, unsanitized form markup (<input>, <label>) — rendering it directly on the page isn't safe. Paste the code into your own page to see it in context.
