Zebra Accordion Â
A tiny (3 KB minified, 1.3KB gzipped), easily configurable, fully customizable, cross-browser jQuery accordion plugin
Zebra Accordion is a tiny (3KB minified, ~1.3KB gzipped) jQuery accordion plugin. It transforms a basic definition list, without requiring any specific markup, into a small-footprint, easily configurable, fully customizable, cross-browser accordion widget, useful for better organizing larger groups of content.
Features
- no additional markup required other than a basic definition list
- no default style allowing you to fully customize it to suit your needs
- works with responsive layouts
- allows for a single expanded tab at a time, or for any number of tabs to be expanded/collapsed
- allows for tabs to expand on mouse over, not just on click
- if an expanded tab's content is not in the viewport it automatically scrolls the browser window so that the content is visible
- callback functions can be used for further customizations
- works in pretty much any browser - Firefox, Chrome, Safari, Edge, Opera and Internet Explorer 6+

How to use
First, load jQuery from a CDN and provide a fallback to a local source like:
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script>window.jQuery || document.write('<script src="path/to/jquery-3.3.1.js"><\/script>')</script>
Load the Zebra Accordion jQuery plugin:
<script src="path/to/zebra_accordion.min.js"></script>
Alternatively, you can load Zebra Accordion from JSDelivr CDN like this:
<!-- for the most recent version, not recommended in production --> <script src="https://cdn.jsdelivr.net/npm/zebra_accordion@latest/dist/zebra_accordion.min.js"></script> <!-- for a specific version --> <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/zebra_accordion.min.js"></script> <!-- replacing "min" with "src" will serve you the non-compressed version -->
Load the style sheet file from a local source
<link rel="stylesheet" href="path/to/zebra_accordion.min.css">
...or from JSDelivr CDN
<!-- for the most recent version --> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/zebra_accordion@latest/dist/zebra_accordion.min.css"> <!-- for a specific version --> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/zebra_accordion.min.css"> <!-- replacing "min" with "src" will serve you the non-compressed version -->
You need a basic definition list for your HTML markup
Don't forget to add the
Zebra Accordion
class to the list container! If you'll have a look you will see that all it does is to setdisplay:hidden
the all the tabs and addcursor:pointer
to titles, so it will not add overweight to your CSS and that you will have to style the accordion to suit your needs.
<dl class="Zebra_Accordion"> <dt>Lorem ipsum dolor sit amet consectetuer</dt> <dd> Lorem ipsum dolor sit amet consectetuer facilisis lacinia sapien ac et.
