Highlights can be combined with Columns to create the subnav effect seen on many pages. To match best, use no background image and toggle the background shading off. This is most commonly placed immediately at the start of the Header Redactor widget in tandem with a Feature, but can be used in other ways as well.
Highlights change the display behavior of cards rendered inside them. This is used to create the quasi-nav listings on some pages.
Certain Highlight sections on our site make use of the parallax effect for backgrounds.
