+ * MCI Footnotes logo

+ * The classes with 'heading' fixing display in dashboard
+ * have all their rules moved to settings.css so as to alleviate
+ * the common stylesheet. Still these rules are only used if the
+ * Footnotes ad link logo is present in the page footer per user
+ * dashboard setting. Making these rules conditional like those
+ * pertaining to tooltips, either jQuery or alternative, would
+ * double the number of united minified stylesheets shipped with
+ * the plugin. Hence these are present by default at the bottom.
