Free Bootstrap 5 Cookie Consent Banner for React — Glassmorphism by pGento

Install Bootstrap 5 for React

Create a React project with Vite and install Bootstrap:

npm create vite@latest my-app -- --template react
cd my-app
npm install
npm install bootstrap

Save the generated theme.css next to the component; the component file already imports bootstrap/dist/css/bootstrap.min.css and ./theme.css. No Bootstrap JavaScript is required — interactivity uses useState.

Use the cookie consent banner in React

// App.jsx
import CookieConsent from './CookieConsent';

export default function App() {
  return <CookieConsent />;
}

Making the banner actually compliant

  • Block before consent: load analytics/marketing tags only after the cookie-consent event reports the matching category (or set Google Consent Mode v2 defaults to denied before tags load).
  • Equal choice: keep “Reject all” on the first layer with the same visual weight as “Accept all”.
  • Withdrawal: keep the “Cookie settings” button (or a footer link) available on every page.
  • Record: the stored choice includes a timestamp; bump CONSENT_KEY when your purposes change to re-ask.

This is an implementation pattern, not legal advice — have your privacy counsel review the wording and categories for your jurisdictions.

Accessibility & customization

The banner is a labelled region (role="region" with aria-label) rather than a blocking modal, preference toggles are native checkboxes with labels, and the always-available “Cookie settings” button lets keyboard users reopen it.

Every color, radius and dark-mode choice is baked into plain Bootstrap classes plus a tiny CSS-variable theme file, so the copied code has no runtime dependency on this site. The glass style relies on backdrop-filter, supported in all current browsers; place it over a colorful background for the best effect.
