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.

• 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+

Zebra Accordion has no dependencies other than jQuery 1.7.0+

Zebra Accordion is available as a npm package. To install it use:

# the "--save" argument adds the plugin as a dependency in packages.json
npm install zebra_accordion --save

First, load jQuery from a CDN and provide a fallback to a local source like:

<script src="https://code.jquery.com/jquery-3.5.0.min.js"></script>
<script>window.jQuery || document.write('<script src="path/to/jquery-3.5.0.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 set display:hidden the all the tabs and add cursor: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.
