Hi there!

You can create a cookie consent banner in Webflow by combining design elements with custom code. Here’s a detailed approach:

First, create the banner design:

  1. Add a div element with position: fixed and set it as a popup wrapper
  2. Design your banner inside this wrapper with text explaining cookie usage
  3. Add “Accept” and “Decline” buttons, giving them unique IDs (e.g., “acceptCookies” and “declineCookies”)
  4. Style the banner to match your site’s design, ensuring it’s visible but not intrusive

Make it functional:

  1. Convert the banner to a component
  2. Add it to your site’s Master pages or individual pages as needed
  3. In Site settings > Custom code > Footer code, add this JavaScript:
document.addEventListener('DOMContentLoaded', function() {
    const banner = document.getElementById('cookieBanner');
    if (!localStorage.getItem('cookieConsent')) {
        banner.style.display = 'block';
    }
    
    document.getElementById('acceptCookies').addEventListener('click', function() {
        localStorage.setItem('cookieConsent', 'accepted');
        banner.style.display = 'none';
    });
    
    document.getElementById('declineCookies').addEventListener('click', function() {
        localStorage.setItem('cookieConsent', 'declined');
        banner.style.display = 'none';
    });
});

Remember to adjust the IDs in the JavaScript to match the ones you used in your design. The banner will appear to new visitors and stay hidden for returning users who have already made their choice.

Hopefully this helps! If you still need assistance, please reply here so somebody from the community can help.

I have not seen a WF-specific tutorial. The AI gen code here covers the UX but it doesn’t actually do any cookie suppression.

Normally, you need to e.g. supress all of your tracking scripts ( GA4, Adwords, FB pixel, Posthog, etc. ) until the user accepts cookies. There are a few hacks for that, like giving the scripts invalid type strings so they won’t load automatically, and then script-changing it later.

The most common setup I see these days is that privacy specialists will setup everything inside of GTM, and distinguish between cookie types- ads, tracking, personalization, stats and so on. Then the client side cookie script can inform GTM and GTM can enable the appropriate stuff.

None of this is Webflow-specific, you should just be able to search for cookie consent setups and GTM and learn how to engineer your own. Make sure to test it thoroughly for compliance, or all of that work is meaningless.
