What is the Hero · centred block for?
A focused opening where the message is the main visual. The Hero · centred block is a strong choice when the offer does not need a large image to make sense. An eyebrow, headline, subhead and primary CTA create the opening, while size, width, background, colours and spacing can be tuned to the situation.
A good starting point: use medium or large on a homepage or campaign page, and often compact on inner pages. When in doubt, start medium with a short headline and one concrete CTA.
