You can change the color scheme with css variables inside cookieconsent.css. You can also change some basic layout options via the gui_options inside the config. object; example:
cookieconsent.run({
// ...
gui_options: {
consent_modal: {
layout: 'cloud', // box/cloud/bar
position: 'bottom center', // bottom/middle/top + left/right/center
transition: 'slide', // zoom/slide
swap_buttons: false // enable to invert buttons
},
settings_modal: {
layout: 'box', // box/bar
// position: 'left', // left/right
transition: 'slide' // zoom/slide
}
}
//...
});Default layout is box and default transition is zoom.
You can alter the color scheme by overriding the available css variables which you can find here.
How to build an ad-hoc stylesheet with your color scheme:
- make sure you have nodejs installed
- download/clone this repo.
- run
npm install - modify
src/cookieconsent.css(css variables that will apply to IE are under the:rootcss selector) - run
npm run build - use the newly generated
dist/cookieconsent.cssstylesheet
Alternatively, you could load a css variables polyfill.
You can manage any script (inline or external) via the page_scripts option:
-
Enable page scripts management:
cookieconsent.run({ // ... page_scripts: true // ... });
-
Set
type="text/plain"anddata-cookiecategory="<category>"to anyscripttag you want to manage:<script type="text/plain" data-cookiecategory="analytics" src="analytics.js" defer></script> <script type="text/plain" data-cookiecategory="ads"> console.log('"ads" category accepted'); </script>
Note:
data-cookiecategorymust be a valid category defined inside the configuration object
After getting the plugin like so:
var cookieconsent = initCookieConsent();the following methods are available:
- cookieconsent
.run(<config_object>) - cookieconsent
.show(<optional_delay>, <create_modal>) - cookieconsent
.hide() - cookieconsent
.showSettings(<optional_delay>) - cookieconsent
.hideSettings()
Additional methods for an easier management of your scripts and cookie settings (expand them to see usage example):
-
cookieconsent
.accept(<accepted_categories>, <optional_rejected_categories>)[v2.5.0+]- accepted_categories:
stringorstring[] - rejected_categories:
string[]- optional
Note: all categories marked as
readonlywill ALWAYS be enabled/accepted regardless of the categories provided inside the.accept()API call.Examples:
cookieconsent.accept('all'); // accept all categories cookieconsent.accept([]); // accept none (reject all) cookieconsent.accept('analytics'); // accept only analytics category cookieconsent.accept(['cat_1', 'cat_2']); // accept only these 2 categories cookieconsent.accept(); // accept all currently selected categories inside modal cookieconsent.accept('all', ['analytics']); // accept all except "analytics" category cookieconsent.accept('all', ['cat_1', 'cat_2']); // accept all except these 2 categories
How to later reject a specific category (cookieconsent already accepted)? Same as above:
cookieconsent.accept('all', ['targeting']); // opt out of targeting category
- accepted_categories:
-
cookieconsent
.allowedCategory(<category_name>)Note: there are no default cookie categories, you create them!
A cookie category corresponds to the string of the
valueproperty inside thetoggleobject:// ... toggle: { value: 'analytics', // cookie category enabled: false, // default status readonly: false // allow to enable/disable // reload: 'on_disable', // allows to reload page when the current cookie category is deselected } // ...
Example:
// Check if user accepts cookie consent with analytics category enabled if (cookieconsent.allowedCategory('analytics')) { // yoo, you might want to load analytics.js ... };
-
cookieconsent
.validCookie(<cookie_name>)If cookie exists and has non empty (
'') value => returntrue, otherwisefalse.// Example: check if '_gid' cookie is set if (!cookieconsent.validCookie('_gid')) { // yoo, _gid cookie is not set, do something ... };
-
cookieconsent
.eraseCookies(<cookie_names>, <optional_path>, <optional_domains>)[v2.5.0+]- cookie_names:
string[] - path:
string- optional - domains:
string[]- optional
Examples:
cookieconsent.eraseCookies(['cc_cookies']); // erase "cc_cookie" if it exists cookieconsent.eraseCookies(['cookie1', 'cookie2']); // erase these 2 cookies cookieconsent.eraseCookies(['cc_cookie'], "/demo"); cookieconsent.eraseCookies(['cc_cookie'], "/demo", [location.hostname]);
- cookie_names:
-
cookieconsent
.loadScript(<path>, <callback_function>, <optional_custom_attributes>)Basic example:
cookieconsent.loadScript('https://www.google-analytics.com/analytics.js', function(){ // Script loaded, do something });
How to load scripts with custom attributes:
cookieconsent.loadScript('https://www.google-analytics.com/analytics.js', function(){ // Script loaded, do something }, [ {name: 'id', value: 'ga_id'}, {name: 'another-attribute', value: 'value'} ]);
-
cookieconsent
.set(<field>, <object>)[v2.6.0+]The
.set()method allows you to set the following values:- data (used to save custom data inside the plugin's cookie)
- revision
How to save custom
data:// Set cookie's "data" field to whatever the value of the `value` prop. is cookieconsent.set('data', {value: {id: 21, country: "italy"}}); // Only add/update the specified props. cookieconsent.set('data', {value: {id: 22, new_prop: 'new prop value'}, mode: 'update'});
-
cookieconsent
.get(<field>)[v2.6.0+]The
.get()method allows you to retrieve any of the fields inside the plugin's cookie:cookieconsent.get('level'); // retrieve all accepted categories (if cookie exists) cookieconsent.get('data'); // retrieve custom data (if cookie exists) cookieconsent.get('revision'); // retrieve revision number (if cookie exists)
-
cookieconsent
.getConfig(<field>)[v2.7.0+]The
.getConfig()method allows you to read configuration options from the current instance:cookieconsent.getConfig('current_lang'); // get currently used language cookieconsent.getConfig('cookie_expiration'); // get configured cookie expiration // ...
-
cookieconsent
.getUserPreferences()[v2.7.0+]The
.getUserPreferences()returns the following object (for analytics/logging purposes):{ accept_type: string, // 'all', 'necessary', 'custom' accepted_categories: string[], // e.g. ['necessary', 'analytics'] rejected_categories: string[] // e.g. ['ads'] }
-
cookieconsent
.updateScripts()[v2.7.0+]This method allows the plugin to manage dynamically added/injected scripts that have been loaded after the plugin's execution.
E.g. dynamic content generated by server side languages like php, node, ruby ...
-
cookieconsent
.updateLanguage(<language>, <force_update>)[v2.8.0+]Use this method to change modal's language dynamically (without page reload).
- language:
string - force_update:
boolean- optional
Example:
cookieconsent.updateLanguage('it');
Note: language will change only if it is valid (already defined) and different from the current language!
You can also forcefully update the modals (useful if you dynamically change the content of the modals). Example:
// Change content: e.g. modify modal title cookieconsent.getConfig('languages').en.consent_modal.title = 'New title'; // Update changes cookieconsent.updateLanguage('en', true);
- language:
Any button (or link) can use the custom data-cc attribute to perform a few actions without manually invoking the api methods.
Valid values:
c-settings: show settings modalaccept-all: accept all categoriesaccept-necessary: accept only categories marked as necessary/readonly (reject all)accept-custom: accept currently selected categories inside the settings modal
Examples:
<button type="button" data-cc="c-settings">Show cookie settings</button>
<button type="button" data-cc="accept-all">Accept all cookies</button>The following functions have to be defined inside the configuration object passed to the .run() method.
-
onAcceptThis function will be executed:
- at the first moment that consent is given (just like
onFirstAction) - after every page load, if consent (accept or "reject" action) has already been given
parameters:
cookie: contains the current value of the cookie
example:
//... cc.run({ // ... onAccept: function(cookie){ // load somescript, google analytics ... }, // ... });

example:
//... cc.run({ // ... onChange: function(cookie, changed_categories){ // cleanup logic ... (e.g. disable gtm if analytics category is disabled) }, // ... });
-
onFirstAction[v2.7.0+]This function will be executed only once, when the user takes the first action (accept/reject).
parameters:
user_preferences: contains the same data provided by the.getUserPreferences()APIcookie: contains the current value of the cookie
example:
//... cc.run({ // ... onFirstAction: function(user_preferences, cookie){ console.log('User accept type:', user_preferences.accept_type); console.log('User accepted these categories', user_preferences.accepted_categories) console.log('User reject these categories:', user_preferences.rejected_categories); }, // ... });

Languages is an object which basically holds all of the text/html of your cookie modals in different languages. In here you can define cookie categories, cookie tables, opt-in/out toggle for each category and more. For each language, a consent_modal object and a settings_modal object must be configured.
Example with multiple languages ('en' and 'it')
cookieconsent.run({
// ...,
languages: {
'en': {
consent_modal: {
title: 'Title here ...',
description: 'Description here ...',
primary_btn: {
text: 'Accept',
role: 'accept_all' // 'accept_selected' or 'accept_all'
},
secondary_btn: {
text: 'Settings',
role: 'settings' // 'settings' or 'accept_necessary'
}
},
settings_modal: {
title: 'Cookie preferences ...',
save_settings_btn: 'Save settings',
accept_all_btn: 'Accept all',
blocks: [
{
title: 'First block title ...',
description: 'First block description ...'
}, {
title: 'Second block title ...',
description: 'Second block description ...',
toggle: {
value: 'my_category1',
enabled: true,
readonly: true
}
}, {
title: 'Third block title ...',
description: 'Third block description ...',
toggle: {
value: 'my_category2',
enabled: false,
readonly: false
}
}
]
}
},
'it': {
consent_modal: {
title: 'Title in italian here ...',
description: 'Description in italian here ...',
primary_btn: {
text: 'Accept in italian',
role: 'accept_all' //'accept_selected' or 'accept_all'
},
secondary_btn: {
text: 'Settings',
role: 'settings' //'settings' or 'accept_necessary'
}
},
settings_modal: {
title: 'Cookie preferences ...',
save_settings_btn: 'Save settings in italian',
accept_all_btn: "Accept all",
blocks: [
{
title: 'First block title in italian ...',
description: 'First block description in italian ...'
}, {
title: 'Second block title in italian ...',
description: 'Second block description in italian...',
toggle: {
value: 'my_category1',
enabled: true,
readonly: true
}
}, {
title: 'Third block title in italian ...',
description: 'Third block description in italian...',
toggle: {
value: 'my_category2',
enabled: false,
readonly: false
}
}
]
}
}
}
});Example with custom cookie table
You can create tables with a custom number of columns to explain what each cookie does.
NOTE: If you want to also use autoclear_cookie, make sure the first column of the cookie table contains the name of the cookie.
Check demo app.js which has a full example with cookie table.
Note:
- default revision number is 0
- if existing revision number is different from the one you just specified => show consent modal
-
Enable revisions by specifying a valid
revisionparameter:cookieconsent.run({ // ..., revision: 1, // ... })
-
Set a valid
revision_messageparameter (optional) insideconsent_modal, and add the following placeholder{{revision_message}}insidedescription:cookieconsent.run({ // ..., revision: 1, // ..., languages: { en: { consent_modal: { // ..., description: 'Usual description ... {{revision_message}}', revision_message: '<br> Dude, my terms have changed. Sorry for bothering you again!', // ... }, // ... } } // ... })

How to integrate with my multi-language website
If you have multiple versions of your html page, each with a different <html lang="..." > attribute, you can grab this value using:
document.documentElement.getAttribute('lang');
and then set it as
current_langvalue like this:cookieconsent.run({ // ... current_lang: document.documentElement.getAttribute('lang'), // ... });
Note: make sure that the lang attribute's value format (example: 'en' => 2 characters) is identical to the ones you defined. If you have 'en-US' as lang attribute, make sure to also specify 'en-US' (and not just 'en') in the config. parameters.

How to load scripts after a specific cookie category has been accepted
Suppose you have a
analytics.jsfile you want to load after theanalyticscategory has been accepted:-
Method 1 (recommended)
-
enable
page_scripts:cookieconsent.run({ // ... page_scripts: true, // ... });
-
add a
<script>tag with the following attributes:type="text/plain"anddata-cookiecategory="<category>"<script type="text/plain" data-cookiecategory="analytics" src="<path-to-analytics.js>"></script>
-
-
Method 2
Load script using the
.loadScript()method inside theonAcceptmethod:cookieconsent.run({ // ... onAccept: function () { if (cookieconsent.allowedCategory('analytics')) { cookieconsent.loadScript('<path-to-analytics.js', function () { // script loaded ... }); } } })

Make consent required (block page navigation until action)
This is a css only solution:
- enable
force_consentoption:cookieconsent.run({ // ... force_consent: true, // ... });
- That should do it. If you want to remove the weird horizontal jump (due to the scrollbar disappearing) you can add the following style inside the head tag of your page:
<style> html, body { height: auto!important; width: 100vw!important; overflow-x: hidden!important; } </style>
For a full example check the second demo.

CookieConsent.jsimport { useEffect } from "react"; import 'vanilla-cookieconsent'; import 'vanilla-cookieconsent/dist/cookieconsent.css'; export default function CookieConsent() { useEffect(() => { if (!document.getElementById('cc--main')) { window.CookieConsentApi = window.initCookieConsent(); window.CookieConsentApi.run({ // your config }); } }, []); return null; }
