Banner 21 block design & features
Banner21 is a full-bleed marquee strip built with shadcn/ui Separator. A top and bottom hairline border frames a single row of short feature phrases, each divided by a short vertical rule, duplicated so the loop can scroll without a visible seam.
Color treatment stays monochrome against the page background with medium-weight small type. Motion is continuous and linear, with overflow clipped so the track reads as an infinite ticker. Spacing between phrases is even and compact.
The feel is modern and lightly kinetic, more ticker tape than announcement card. Complexity is moderate but CSS-driven: the animation and duplicated list do the work, while content needs only a short string array of benefit phrases.
