+When the Browser Window reaches a small enough width or the amount of Bookmarks overlap the browsers width, overlapping bookmark items are:
+1. set to hidden. 
+2. duplicated into the overflow menu.
+
+This style will simply:
+1. enable scrolling on the toolbar.
+2. restore visibility of hidden bookmarks.
+
+You can use the scrollable toolbar alongside the overflow menu by removing Lines 16-19
