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.
Cookie Banner script is very lightweight and depends on no JavaScript libraries, css files or images.
To see the script in action, visit the Good Code web page.
Add a single line to your web page, just before the closing </body>
tag:
<script type="text/javascript" id="cookiebanner"
src="http://cookiebanner.eu/js/cookiebanner.min.js"></script>
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
script
tag:
height
- banner height (default: 32 pixels)fg
- banner text color (default:#ddd
)bg
- banner background color (default:#000
)link
- link text color (default:#aaa
)position
- banner position,top
orbottom
(default:bottom
)message
- the message textlinkmsg
- the link text content (default:Learn more
)close-text
- the text/symbol for the close button (default:✖
)font-size
- the text size of the message and the link (default:14px
)font-family
- the font family of the message and the link (default:arial, sans-serif
)text-align
- The position of the text (default:center
)effect
- effect to usecookie
- name for the cookie to store the cookiebanner acceptance information (default:cookiebanner-accepted
)expires
- cookie expiry date/time (defaults toInfinity
akaFri, 31 Dec 9999 23:59:59 GMT
). There's basic support for specifying a callback function (more flexibility, must return one ofNumber
,String
, orDate
-- seeCookies.set()
). You can also just specify a valid UTC string.cookie-path
- Path to set for the cookiemoreinfo
- where the visitor can read more about cookies (default: http://aboutcookies.org)mask
- whether to create a mask over the viewport (default:false
). Clicking anywhere on the mask is considered as acceptance.mask-opacity
- the opacity to use for the window mask (default:0.5
)mask-background
- optional background style you wish to apply to themask
(default:#000
)zindex
- z-index to set on the notice (default:255
). Ifmask
is used, the notice's z-index is automatically incremented by 1 so it appears above the mask)accept-on-scroll
- when is settrue
window scrolling is considered as acceptance. (default:false
)
Here's an example:
<script type="text/javascript" id="cookiebanner"
src="//cookiebanner.eu/js/cookiebanner.min.js"
data-height="20px" data-position="top"
data-message="We use cookies to improve your browsing experience.">
</script>
If you don't want to depend on the cookiebanner.eu
site, you can copy
the 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.
If the banner needs to be shown, the script will create the following DOM
subtree and add it just before the closing </body>
tag:
<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 lint # run jshint to check the code
make test # run the tests
make # minify it
You'll need jshint
and uglifyjs
tools installed for this, and also
phantomjs
if you want to run the tests.
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
make test
- there should be no external JavaScript, CSS, image files or any other dependencies
- the code should work with no errors or warnings on recent Chrome, Firefox, Safari, Internet Explorer browsers and iOS and Android platforms
- 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
