jQuery UI Datepicker Bootstrap 5 Style

jquery-bootstrap5-datepicker.css

/* 
 * Based on: https://gist.github.com/miwahall/7028640
 * And the idea of gordon-matt
 *
 * Works with Bootstrap 5.0.0-beta2, the Icons used are also new Bootstrap Svg Icon set (1.3.0)
 * The final design isn't 110% perfect.
 *
 * Used libs:
 * 
 * jquery-3.5.1.min.js
 * jquery-ui.min.js	(1.12.1)
 * bootstrap.min.cs	(5.0.0-beta2)
 * bootstrap.min.js	(5.0.0-beta2)
 * bootstrap-icons.css	(1.3.0)
