The promo section has two main areas for dynamic content, the background image and foreground copy. The copy appears over the image when in tablet or desktop view while the text will appear below the image in mobile view. One main feature about the promo section is that the height is dependent on the background image. Specs below should help determine the most optimal sizing but if the copy height exceeds the height of the image, then you may see some unwanted results.
