flowmanceFufo Design System
Fufo is a strict, monochrome marketing agency site. It reads like a printed broadsheet: pure white page, pure black General Sans at weight 500, and full-width 1px black rules that box every section into a grid. Colour comes only from the photography; the interface is black, white and two greys.
Four signatures make it recognisable:
- Grey words inside black headlines. Long statements switch part of the sentence to ink-faint #8F8F8F and back to black for the final full stop: FUFO has become a leader in black, digital experiences, web design and branding grey, . black.
- Circular buttons. The main calls to action are 180px black discs with white uppercase labels (GET IN TOUCH, JOIN OUR TEAM), and the headline metric $700M sits inside a 1px outlined circle about 550px across.
- Ruled grid. A 1px black rule runs under the nav, between sections and around the services grid, whose cells share hairline borders like a table.
- Stacked logotype. The FU / FO logo is set in two lines in the centre of the nav, with a tagline at the left and a cart and + menu icon at the right.
Fufo is a light-only design.

Do’s and don’ts
- Keep the page pure #FFFFFF with #000000 text, and set body copy in full black.
- Separate sections and cells with 1px solid #000000 rules, edge to edge inside the 2% gutter.
- Use the 180px black circle button for the main call to action, with a 14px weight-600 uppercase label at 1px tracking.
- Set every headline in General Sans weight 500 with 0 letter spacing.
- Grey out the middle phrase of long statements with ink-faint #8F8F8F and close with a black full stop.
- Keep images square-cornered.
- Add an accent colour, gradients, shadows or tinted panels.
- Use ink-faint #8F8F8F under 24px; it only works inside large headlines.
- Use bold weights in headlines; 700 is for the overlay menu only.
- Round cards, images or inputs. Only circles and the 4px .button have curves.
- Use grey borders. Lines are black.
- Animate longer than 1000ms or add bouncy movement outside the menu.

Best for
Claude, ChatGPT, Gemini, Cursor and v0, or any other AI tool that builds pages or code.
How to use it

DESIGN.mdin your project and mention it in your request, or save it as.cursor/rules/fufo.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

Best for
Figma (Tokens Studio), Style Dictionary and other design-token tools, and build scripts.
How to use it
- In Figma, open Tokens Studio, choose Import, and pick
tokens.json - Or point Style Dictionary’s

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.

Tailwind v4 projects, and AI builders that write Tailwind (v0, Lovable, Bolt).
How to use it
- Save
theme.cssnext to your main CSS file - Import it after Tailwind:
@import "tailwindcss"; @import "./theme.css"; - Use the classes:
bg-canvas text-ink rounded-md p-lg

The same tokens as plain CSS variables on :root. Component values point at the color variables, so changing one color updates everything that uses it.
Best for
Any website: plain CSS, Webflow custom code, Framer, WordPress.
How to use it
- Add it to your stylesheet, or in Webflow paste it into Site settings → Custom code inside a
<style>tag - Use the variables anywhere:
