Fun Facts

• Styling native HTML form elements was nearly impossible before CSS3 — developers routinely rebuilt selects, checkboxes, and radios entirely in JavaScript for visual consistency.
• The CSS accent-color property, added to browsers in 2021, was the first standard way to theme native checkboxes, radios, and range inputs without JavaScript replacement.
• A 2019 Baymard Institute study found that 18% of e-commerce checkout abandonments were caused by confusing form design — proper input styling directly impacts conversion rates.

FAQ

Which form controls does it style?

Text inputs, textareas, selects, checkboxes (via custom styler), radios, and buttons. File inputs aren't directly stylable — the tool includes the common label-wrapping workaround.

Does it handle invalid states?

Yes — :invalid and :user-invalid styles are included. :user-invalid only applies after interaction, which is better UX than showing red borders before typing.

What about focus rings?

A 2px offset outline on :focus-visible. The color is tied to the accent token so the whole form feels consistent.

Is the output mobile-friendly?

Yes — default padding is tall enough for 44px touch targets. Input font-size is 16px to avoid iOS zoom-on-focus.
