Cookie Banner is a super-easy way to ensure you're complying with the EU
cookie law. Just reference the
cookiebanner.min.js script from your page
and you're done.
To see the script in action, visit the Good Code web page.
Add a single line to your web page, just before the closing
This will display a black-and-white floating banner at the bottom of your web page, informing the user that the site is using cookies, and giving them the link to a page with more information.
When the user clicks the "close" button, the banner will set a cookie (oh, the irony!) remembering that the banner was acknowledged, so the same user will not be bothered again.
If you don't like the defaults, you can modify the banner content and
style. The following options are settable through a
data- property on the
height- banner height (default: 32 pixels)
fg- banner text color (default:
bg- banner background color (default:
link- link text color (default:

message- the message text

effect- effect to use
cookie- name for the cookie to store the cookiebanner acceptance information (default:
expires- cookie expiry date/time (defaults to
Fri, 31 Dec 9999 23:59:59 GMT). There's basic support for specifying a callback function (more flexibility, must return one of
Cookies.set()). You can also just specify a valid UTC string.
cookie-path- Path to set for the cookie
moreinfo- where the visitor can read more about cookies (default: http://aboutcookies.org)
mask- whether to create a mask over the viewport (default:

Here's an example:
If you don't want to depend on the
cookiebanner.eu site, you can copy
cookiebanner.min.js directly to your site.
If you're using SSL, you'll also need to host the file yourself, as Amazon S3 service that we're using for hosting doesn't support adding custom SSL certificates.
Internals and more options
If the banner needs to be shown, the script will create the following DOM
subtree and add it just before the closing
<div class="cookiebanner"> <div class="cookiebanner-close" style="float: right; padding-left:5px;">x</div> <span>Message</span> <a href=".." target="_blank">Learn more</a> </div>
You can use CSS with
div.cookiebanner > span and
div.cookiebanner > a to
further modify the banner appearance.
You can also try customizing the close button via the
.cookiebanner-close CSS class.
Keep in mind that you might have to override and/or reset certain properties by using
!important CSS rules.

If you've modified the code, it's recommended you run it through linter to catch potential errors, and minifier to minimize its footprint.
We're old-school here so we just use Makefile for the tasks:
make check # run jshint to check the code make # minify it
uglifyjs tools installed for this.
Pull requests are welcome! In order to get your pull-request accepted, please follow these simple rules:
- all code submissions must pass cleanly (no errors) with

- if you want to add significant features, file an issue about it first so we can discuss whether the addition makes sense for the project
