JavaScript preprocessors can help make authoring JavaScript easier and more convenient. For instance, CoffeeScript can help prevent easy-to-make mistakes and offer a cleaner syntax and Babel can bring ECMAScript 6 features to browsers that only support ECMAScript 5.
Any URL's added here will be added as <script>
s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.
You can apply a script from anywhere on the web to your Pen. Just put a URL to it here and we'll add it, in the order you have them, before the JavaScript in the Pen itself.
If the script you link to has the file extension of a preprocessor, we'll attempt to process it before applying.
You can also link to another Pen here, and we'll pull the JavaScript from that Pen and include it. If it's using a matching preprocessor, we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

<h1>CSS + HTML only Accordion Element</h1>
<ul>
<li>
<input type="checkbox" checked>
<i></i>
<h2>Languages Used</h2>
<p>This page was written in HTML and CSS. The CSS was compiled from SASS. I used Normalize as my CSS reset and -prefix-free to save myself some headaches. I haven't quite gotten the hang of Slim for compiling into HTML, but someday I'll use it since its syntax compliments that of SASS. Regardless, this could all be done in plain HTML and CSS.</p>
</li>
<li>
<input type="checkbox" checked>
<i></i>
<h2>How it Works</h2>
<p>Using the sibling and checked selectors, we can determine the styling of sibling elements based on the checked state of the checkbox input element. One use, as demonstrated here, is an entirely CSS and HTML accordion element. Media queries are used to make the element responsive to different screen sizes.</p>
</li>
<li>
<input type="checkbox" checked>
<i></i>
<h2>Points of Interest</h2>
<p>By making the open state default for when :checked isn't detected, we can make this system accessable for browsers that don't recognize :checked. The fallback is simply an open accordion. The accordion can be manipulated with Javascript (if needed) by changing the "checked" property of the input element.</p>
