+ * Top navigation bar. Features of the bar:
+ * - Hide content if the display width is less than 768px. In this case the menu icon is displayed.
+ *   When the icon is clicked, the menu content is displayed on the left side of the page.
+ * - If the content doesn't fit the navbar, it can be dragged left and right.
+ *
+ * Dependences:
+ * - DragScroll (winter.dragscroll.js)
+ * - VerticalMenu (winter.verticalmenu.js)
