Code:

add_action( 'wp_head', 'custom_cookie_consent' );
/**
 * Add Cookie Consent bar.
 * 
 * @link https://cookieconsent.insites.com/download/ Code generated from here.
 */
function custom_cookie_consent() { ?>

    <link rel="stylesheet" type="text/css" href="//cdnjs.cloudflare.com/ajax/libs/cookieconsent2/3.1.0/cookieconsent.min.css" />
    <script src="//cdnjs.cloudflare.com/ajax/libs/cookieconsent2/3.1.0/cookieconsent.min.js"></script>
    <script>
    window.addEventListener("load", function(){
    window.cookieconsent.initialise({
      "palette": {
        "popup": {
          "background": "#000"
          },
        "button": {
          "background": "#f1d600"
          }
      }
    })});
    </script>

<?php }
