Capita X Design System
Capita X is a calm, trustworthy accounting and finance site. It reads like a modern firm's brochure: a white page, heavy but friendly BDO Grotesk headlines at weight 600, deep pine-green bands that carry the serious parts (services, FAQ), and small flashes of signal green on icons and toggles. Almost everything is set in one weight (600), so the hierarchy comes from size and from the green bands, not from contrast in weight.
Three signatures make it recognisable:
- Diagonal cuts. The hero photo ends in a white angled wedge on the lower right, and the pine services band is sliced by steep diagonals, so the white service cards appear to sit on a torn green slab. The page never uses rounded section corners; it uses angles.
- Pine pill + arrow. Main actions are 120px-radius pills in primary #02413E (or a white 2px outline on dark), label type, with a thin → after the label: Meet the Team →, Learn More →, Book a Consultation →.
- Mint icon circles. Feature and service icons are thin signal-green (#079C41) line icons centred in about 85px pale mint (#F6F9F5) circles, placed above a title-md heading.
Capita X is a light design with dark-green bands, not a dark theme.

Do’s and don’ts
- Use primary #02413E pills with on-primary #FFFFFF text and a → for every main action.
- Put serious blocks (services, FAQ) on inverse-canvas #02413E with white text, and keep the rest on #FFFFFF.
- Set body copy in black (#000000) at weight 600, 17px, line height 1.4.
- Place every feature icon as a #079C41 line icon inside a #F6F9F5 circle.
- Use diagonal cuts to end photo and pine areas instead of rounded corners.
- Tint photos that sit behind text with the #02413E 40% scrim.
- Put white text on accent #079C41 at small sizes; it only reaches about 3.6:1. Keep green for icons and round toggles.
- Add drop shadows to cards; only the blog image hover and dropdown have shadows.
- Use a second typeface or mix weights; stay with BDO Grotesk 600.
- Round sections or cards; only pills, inputs (30px), circles and blog images (7px) are rounded.
- Introduce grey paragraph text or a new brand colour.
- Animate longer than 1000ms or add bounce, apart from the 400ms swingTo chevron.

<style>tag - Use the variables anywhere:
