flowmanceCosa Design System
Cosa is a loud, upbeat agency template. It swings between deep colour bands (maroon #3C141D, then midnight blue #032535) and plain white sections, and it sets everything in heavy DM Sans 700 with a tomato-orange accent (#FF6441). The mood is "friendly studio": smiling round portraits, hand-painted brush strokes, numbered rings and short punchy headlines.
Four signatures make it recognisable:
- The brush-stroke highlight. In the hero one word (create) sits on a ragged tomato paint swipe, while the rest of the 90px headline stays white on maroon.
- Floating round portraits. Four circular team photos (about 100–160px) drift in the hero corners, each with a soft 0 8px 25px black-20% shadow, around a thin wavy-line pattern.
- Ringed numbers. Indexes sit in circles of about 60px with a 2px tomato border: 1 Portotyping in the services list, 01–04 pinned to the top-left of each project image.
- Tomato eyebrows. Every section opens with an uppercase eyebrow in tomato, 16px bold with 2px tracking (CRAFT, DESIGN & SMILE, WHAT WE DO, OUR PROJECTS). On the blue band it switches to turquoise #0CE5E1 (WE ARE COSA).

Do’s and don’ts
- Alternate maroon #3C141D or midnight blue #032535 bands with white #FFFFFF sections.
- Open each section with an eyebrow (16px, 700, 2px tracking, uppercase) in tomato, or turquoise on the midnight-blue band, then a 58px headline-lg.
- Use DM Sans 700 for every heading and 500 for text, with 0 letter spacing.
- Keep buttons at 60px tall with a 3px radius: tomato #FF6441 for the main action, #F2F2F4 for the second.
- Put indexes in circles of about 60px with a 2px #FF6441 ring.
- Set paragraphs on dark bands in white at 80% (#FFFFFFCC).
- Put white text on tomato below 16px bold. #FFFFFF on #FF6441 is only 2.94:1, so keep button labels at 16px weight 700 or larger.
- Use tomato #FF6441 for body text on white. It is 2.94:1, so keep it to short bold eyebrows and 16px bold arrow links.
- Use ink-subtle #A7A7A7 for anything but 17px+ hashtag tags; it is 2.41:1 on white.
- Round buttons or cards beyond 5px, or turn buttons into pills. Only portraits and number rings are circles.
- Add shadows to cards or buttons. The single shadow belongs to the floating hero portraits.
- Use turquoise #0CE5E1 on white or maroon; it is for the midnight-blue band only.
- Use Josefin Slab or the declared Tuesday Night face; the template renders only DM Sans.

Claude, ChatGPT, Gemini, Cursor and v0, or any other AI tool that builds pages or code.
How to use it
- Put
DESIGN.mdin your project and mention it in your request, or save it as.cursor/rules/cosa.mdc - For the rule file, start it with a front-matter block that sets
alwaysApply: true, so every chat uses it - Ask: “Build a pricing page using DESIGN.md.” Cursor follows the colors, fonts, spacing and rules
- Put
DESIGN.mdin the project root - Add one line to
CLAUDE.md: “Follow DESIGN.md for all UI.” - Ask for any page or component; Claude reads the file first
- Attach
DESIGN.mdto the chat (or paste it in) - Ask: “Build a landing page in this design system.”
- Keep the file in the chat or project knowledge, so follow-up pages stay on style

What it is
A Tailwind CSS v4 theme: every color, font, type style, radius and spacing value becomes a Tailwind utility, like bg-canvas, text-headline-lg or rounded-md.

- Add it to your stylesheet, or in Webflow paste it into Site settings → Custom code inside a
<style>tag - Use the variables anywhere:
