CSS Input Generator

Design a text field — outline, filled, underline or soft style, a label (static or floating), placeholder, helper and error text, leading / trailing icons or affixes, a focus ring, size and radius, plus a clear button, character counter and password reveal — previewed in every state, with HTML + CSS + JS output or SCSS / Tailwind / React.

What this tool does

It builds the markup and CSS for a form field — label, control, helper text and the focus / error styling — and previews every state live.

Styles

Outline is a bordered box. Filled is a tinted box with a bottom border. Underline is a single line. Soft is a rounded fill with no border until focus.

Floating label

The label sits inside the field and moves up on focus or when the field has a value, using :placeholder-shown and :focus-within — no JavaScript.

Affixes and icons

Add a leading or trailing icon, or a short text affix like $ or .com, inside the field border.

Extras

An optional clear button, a live character counter, and a show / hide toggle for password fields — each a few lines of JS included in the output.

Output

HTML + CSS (+ JS), SCSS with variables, Tailwind classes, or a React component.

Privacy

Everything runs in your browser. Nothing is uploaded.

Frequently asked questions

Does the floating label need JavaScript?
No. It uses :placeholder-shown (true when the field is empty) plus :focus-within to decide whether the label is "up" or "resting". The placeholder is set to a space so the selector works.
How does the error state get applied?
Add aria-invalid="true" to the input (or an .is-error class on the wrapper). The CSS targets that to recolour the border, label and helper text, and the helper slot shows the error message.
Can the field have a currency prefix?
Yes — set a leading affix of "$". It renders inside the border with the input padding adjusted so text does not overlap it.
Is the password reveal accessible?
The toggle is a real
Is anything sent to a server?
No. The field is generated entirely in your browser.
