How to add it

How to add a Dark Mode Contact Form to your site.

To add a Dark Mode Contact Form to your site you need three things: a free splitforms access key, the HTML snippet above, and your key pasted into it. No backend, database, or CAPTCHA library — the form posts to one URL and every submission lands in your inbox and dashboard.

Define color tokens

Set --bg, --ink, --line, --accent in :root. These are your light-mode values.

Override for dark mode

Inside @media (prefers-color-scheme: dark), redefine the same tokens with dark-friendly values. Every color in your form references the tokens, so the whole thing flips.

(Optional) Add a manual toggle

If you want a manual override, add a `data-theme` attribute on `<html>` and additional CSS selectors. Most sites don't need this — system preference is enough.

What's included

What's in this Dark Mode Contact Form template?

OS-level dark mode is the standard in 2026 — every modern browser supports prefers-color-scheme and most visitors have a preference set. A contact form that respects that preference looks polished without any JavaScript or theme-toggle UI. The trick is using CSS custom properties for color tokens and a single @media (prefers-color-scheme: dark) override. Native OS dark mode, no JS, no theme library.

  • Basic contact form — 4 ready-made fields
  • HTML, JS, React, PHP, and cURL outputs
  • One POST endpoint, no SDK — honeypot and classifier, no CAPTCHA

Where submissions go

Where do your Dark Mode Contact Form submissions go?

Reply-to is wired to the visitor's email, so one tap on Reply answers them directly — while the built-in honeypot and spam classifier filter out bots before they reach you. Every submission is emailed to your inbox and can forward to a webhook or Slack the moment a visitor hits send.

  • Reply-to wired to the visitor's email — reply straight from your inbox
  • Honeypot and spam classifier filter bots, no CAPTCHA friction
  • Live dashboard, CSV export, and signed webhooks on paid plans

Testimonials

Loved by developers shipping at every scale.

40 quotes on record — from indie hacks to agency migrations.

Next.js
“I replaced a Lambda + DynamoDB + SES contact form with six lines of HTML. It took eleven minutes, and the dashboard is better than what I was going to build.”
Daniel K.Full-stack developer
Agency
“We migrated 14 client sites off Formspree in a single weekend. The price is a third of what we paid, the API is more honest, and the spam filter actually works.”
Priya N.Agency owner
Webhooks
“The webhook payload is signed, idempotent, and well-shaped. It reads like code from a competent team, not a CRUD app held together with duct tape.”
Marcus T.Backend engineer
Marketing
“I stopped reaching for Typeform on small marketing sites. splitforms covers 90% of the use case at none of the bloat.”
Elena R.Freelance designer
MCP
“I onboarded our whole agency in an afternoon. The MCP integration meant Cursor literally dropped the form straight into our client repos for us.”
Sam O.Technical lead
Free plan
“The free plan gave me 500 submissions before I paid a cent, and Pro is five dollars a month. I've spent more on coffee deciding which backend to use.”
Aisha B.Indie hacker
Spam
“Spam went from forty junk entries a day to zero, with no reCAPTCHA puzzle ruining the form. The honeypot and time-trap just quietly do their job.”
Tom W.Webflow consultant
Astro
“Point the form action at one endpoint and you're done. No SDK, no client library, no build step. This is how a form backend should feel.”
Lukas M.Astro developer
Integrations
“Leads land in Slack the second someone submits, and a copy goes to Google Sheets for the sales team. I wired both up in under ten minutes.”
Grace H.Growth marketer
Static site
“I run a static Hugo site on a five-dollar VPS. splitforms gave it a real contact form without me standing up a single server.”

Questions

Dark Mode Contact Form questions.

View all FAQs
Will the dark version work in older browsers?

prefers-color-scheme has been supported since 2018 (Chrome 76, Firefox 67, Safari 12.1). Older browsers see the light theme — which is the safe fallback.

How do I support both system preference AND a manual toggle?

Use a `data-theme="dark"` attribute on `<html>` and write `[data-theme="dark"]` selectors. Default to system preference, override on user action. Persist the choice in localStorage.

Does Tailwind support this pattern?

Yes — Tailwind ships a `dark:` variant. Either base it on system preference (`darkMode: 'media'` in config) or on a class (`darkMode: 'class'`). Both work with splitforms.

What about accessibility for low-contrast issues?

Hit WCAG AA on both themes — at least 4.5:1 for body text, 3:1 for large text. Use a contrast checker on every color combination. Dark mode is where most accessibility bugs hide because designers test light-mode first.
