Over the last couple of years, a new term has arrived in website design. That is "hero banner" or "hero image". Although the term has gained popularity this year, it has been around for a couple of years.
I have noticed a few different ways that a hero banner has been defined. Some have defined it as a home page or a main call-to-action, but that's really not what it is. It is part of a home page (or other important landing pages) and should contain a phenomenal call-to-action. So, why should you be concerned with this aspect of design?
