How to Add a Floating CTA Button to a Next.js App

Next.js uses a root layout file that wraps every page — making it the perfect place to add a site-wide floating CTA button. Design your button with the generator, export the code, and drop it into your layout in under a minute.

Design your CTA button

Open the CTA Button Generator and customize your button using the visual editor. Pick colors, position, animation, hover effects, icon, and font. The live preview updates in real time so you see exactly what your visitors will get.

Export your code

When you are happy with the design, click "Get Code" to export a clean HTML + CSS snippet. The code is lightweight, has zero dependencies, and works on any website.

Create a CtaButton component

Create a new file at components/cta-button.tsx. Paste the exported HTML converted to JSX and include the styles. Since the button is purely presentational, it can be a server component (no "use client" needed).

export function CtaButton() {
  return (
    <>
      <style>{`/* paste your CTA styles here */`}</style>
      {/* paste your CTA HTML here, converted to JSX */}
    </>
  );
}

Add it to your root layout

Open app/layout.tsx and render the <CtaButton /> component inside the <body> tag, after your main content. This ensures it appears on every page.

import { CtaButton } from "@/components/cta-button";

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>
        {children}
        <CtaButton />
      </body>
    </html>
  );
}

Run your dev server and verify

Start your Next.js dev server with npm run dev (or bun dev, pnpm dev). Navigate to any page and confirm the floating CTA button appears in the correct position.

Frequently Asked Questions

Does the CTA button work with both the App Router and Pages Router?

Yes. For the App Router, add it to app/layout.tsx. For the Pages Router, add it to pages/_app.tsx or pages/_document.tsx.

Will it affect server-side rendering?

No. The button is pure HTML + CSS with no client-side JavaScript, so it renders on the server just like any other element.
