/**
* Accordion-folding functionality.
*
* Markup with the appropriate classes will be automatically hidden,
* with one section opening at a time when its title is clicked.
* Use the following markup structure for accordion behavior:
*
* <div class="accordion-container">
* <div class="accordion-section open">
* <h3 class="accordion-section-title"></h3>
* <div class="accordion-section-content">
* </div>
* </div>
* <div class="accordion-section">
* <h3 class="accordion-section-title"></h3>
* <div class="accordion-section-content">
* </div>
* </div>
* <div class="accordion-section">
* <h3 class="accordion-section-title"></h3>
* <div class="accordion-section-content">
* </div>
* </div>
* </div>
*
* Note that any appropriate tags may be used, as long as the above classes are present.
*
* In addition to the standard accordion behavior, this file includes JS for the
* Customizer's "Panel" functionality.
*
* @since 3.6.0.
