Examples
While shadows on components are disabled by default in Bootstrap and can be enabled via $enable-shadows, you can also quickly add or remove a shadow with our shadow attribute. Includes support for shadow="none" and three default sizes (which have associated variables to match).
 No shadow 
 Small shadow 
 Regular shadow 
 Larger shadow
