+/**
+ * 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.
