A Hero Block is a large, eye-catching block that usually contains an image and/or the most important information about your business, like your tagline. They work best underneath your Global Header to form a page header, but can be positioned lower on a page.
To add a Hero Block, go to Add Content > Hero Blocks and drag the selected block onto your site.
