An excerpt from http://www.sitepoint.com/exploring-hero-section/, by @GabrielleG
As defined by the Oxford Dictionary: Hero / ˈhirō/ (noun)
:A person, typically a man, who is admired or idealized for courage, outstanding achievements, or noble qualities
:The chief male character in a book, play, or movie, who is typically identified with good qualities, and with whom the reader is expected to sympathize
:(In mythology and folklore) a person of superhuman qualities and often semi-divine origin, in particular one of those whose exploits and dealings with the gods were the subject of ancient Greek myths and legends.
These are all definitions to a word derived from the Ancient Greek word ἥρως which means heroes. A word that has a rich history dating back to a time where Gods clashed with mythological beasts and championed heroes to fell nasty foes on a path of destruction.
But what does the etymology and history of such a word have to do with web design? In short, if you know how to make mortar you can build something a lot more effective than a straw hut.
##What is the Hero Section?
Sad truth time: the hero section has nothing to do with your favorite comic and movie heroes. That means no Batman, Hellboy, Ironman, Doctor Strange or any other caped crusader.
