Add Cookies to Hugo Site

| 2 minutes read

My blog is based on hugo. And since I use google analytics, I need a cookie notice to be gdpr compliant.

But it was not so easy for me to find a page that describes how to do it. so that will be the content of this article.

Getting started

The first thing we need is control over the theme. I use PaperMod, with which I am also very satisfied. so far.

So we forge the theme into our github and then use the fork as a submodule like this:

git submodule add themes/PaperMod --depth=1

Now we have control and can add code. I base myself on the tutorial by Adam Spann.

First we add the html part to the file Papermod/layouts/_default/baseof.html:

<div class="cookie-container">
    I use cookies on this website to give you the best experience on my blog. To find out more, read our
    <a href="/cookies/">privacy policy and cookie policy</a>.
  <button class="cookie-btn">
    const cookieContainer = document.querySelector(".cookie-container");
    const cookieButton = document.querySelector(".cookie-btn");
    const nopeCookieButton = document.querySelector(".nope-cookie-btn");
    const cookieBannerDisplayed = "cookieBannerDisplayed"
    const analyticsIsAllowed = "analyticsIsAllowed"
    const analyics = () => {
      (function (i, s, o, g, r, a, m) {
        i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () {
          (i[r].q = i[r].q || []).push(arguments)
        }, i[r].l = 1 * new Date(); a = s.createElement(o),
          m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m)
      })(window, document, 'script', '', 'ga');
      ga('create', 'G-Q2W252LSJR', 'auto');
      ga('send', 'pageview');
    if (localStorage.getItem(analyticsIsAllowed) === "true") {

    cookieButton.addEventListener("click", () => {
      localStorage.setItem(cookieBannerDisplayed, "true");
      localStorage.setItem(analyticsIsAllowed, "true");

    nopeCookieButton.addEventListener("click", () => {
      localStorage.setItem(cookieBannerDisplayed, "true");
      localStorage.setItem(analyticsIsAllowed, "false");

    setTimeout(() => {
      if (!localStorage.getItem(cookieBannerDisplayed)) {
    }, 100);

After that we have to style it. Here we simply work in file PaperMod/assets/common/main.css:

.wrapper {
    padding: 2rem;

.cookie-container {
    position: fixed;
    bottom: -100%;
    left: 0;
    right: 0;
    background: #2f3640;
    color: #f5f6fa;
    padding: 0 32px;
    box-shadow: 0 -2px 16px rgba(47, 54, 64, 0.39);

    transition: 400ms;
} {
    bottom: 0;
    display: flex;
    justify-content: space-evenly;
    align-items: center;
    flex-wrap: wrap;

.cookie-container>p {
    margin-top: .5rem;

.cookie-container a {
    color: #f5f6fa;

.cookie-btn {
    margin-top: 1rem;
    background: #e84118;
    border: 0;
    color: #f5f6fa;
    padding: .6rem 1.2rem;
    font-size: 1.2rem;
    margin-bottom: 1rem;
    border-radius: .5rem;
    cursor: pointer;

After that we only need one page for the cookies and then the result looks like this (can also be seen below 😋):


I hope it helped you. As you can see, it is quite easy to create the gdpr comliance in Hugo.
