Cookie Banner

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.

Install

You can install with bower or npm.

$ bower install cookiebanner
$ npm install cookiebanner

Build

$ grunt

Test

$ grunt ci

Quickstart

Add a single line to your web page, just before the closing </body> tag:

<script type="text/javascript" id="cookiebanner"
    src="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.

Options

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:

• position - banner position, top or bottom (default: bottom)
• message - the message text
• linkmsg - the link text content (default: Learn more)
• close-text - the text/symbol for the close button (default: ✖)
• effect - effect to use
• cookie - name for the cookie to store the cookiebanner acceptance information (default: cookiebanner-accepted)
• expires - cookie expiry date/time (defaults to Infinity aka Fri, 31 Dec 9999 23:59:59 GMT). There's basic support for specifying a callback function (more flexibility, must return one of Number, String, or Date -- see 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: 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 the mask
  (default: #000)
• zindex - z-index to set on the notice (default: 255). If mask is used, the notice
  's z-index is automatically incremented by 1 so it appears above the mask)
• close-on-interaction - automatically accept cookie policy after any interaction.

Here's an example:

<script type="text/javascript" id="cookiebanner"
    src="js/cookiebanner.min.js"
    data-position="top"
    data-message="We use cookies to improve your browsing experience.">
</script>

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 </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 customize the banner appearance using css, here's an example using SCSS:

.cookiebanner {
    color: #FFF;
    background-color: #000;
    padding: 5px 16px;

    a {
        color: #FFF;
        text-decoration: underline;
        &:hover {
            color: #aaa;
        }
    }
}

.cookiebanner-close {
    color: #FFF;
    &:hover {
        color: #aaa;
    }
}
