flowmanceAltrum™ Design System
Altrum is an editorial, poster-like agency site. It feels like a printed design annual set on black: huge white Inter headlines, quiet small labels, generous empty space and full-bleed, saturated photography (cobalt blue, signal red, sky grey) that carries all the colour. The interface itself is strictly greyscale.
Three signatures make it recognisable:
- The © mark. Every big section title starts with "©" set in the same weight as the word (©Featured Works, ©Services, ©Let's Talk). Small meta labels use it too (©Edition 03, @Since — 2018).
- The edition header. Every section opens with a hairline rule and a three-part row: + Section name on the left, ©Edition 0N in the middle (muted), and an arrow or text link on the right.
- Poster type with tight tracking. Display sizes run 144–224px with line height 0.85 and letter spacing −6 to −7px. Everything else is Inter 500 at −0.5px.
Altrum is a dark-only design.

Motion
| Text roll on hover (buttons, nav, menu) | The label moves y 0% → −101% while a copy moves 100% → 0%. Characters are staggered, 300–400ms, power1.out going in and power1.in going out. |
| Headline reveal | SplitText into lines. Each line rises from y 100% → 0% inside an overflow-hidden mask, 500ms, power1.out, about 50ms stagger. |
| Fade-up | opacity 0 → 1, y 10px → 0, 400ms, power1.out |
| Icon pop | scale 0.6 → 1, rotation 40° → 0°, 200ms, sine.inOut |
| Work card tilt | rotation 15° → 0°, scale 0.9 → 1, scrubbed by scroll (scrub 0.7–0.8) from the card entering to it reaching 70–90% of the viewport |
| Hero image | scale 1.6 → 1 over the first screen of scroll (scrub 0.8) |
| Underline and menu line wipe | width 0% → 100%, 400ms, power1.in |
| Input focus | 400ms cubic-bezier(0.25, 0.46, 0.45, 0.94) |
Do’s and don’ts
- Start every section with the edition header (line rule, + Name, ©Edition 0N, link), then a ©Title in display-section.
- Keep all UI greyscale: canvas #070707, surface-1 #181818, ink #FFFFFF.
- Set body copy at ink-muted (white at 70%), never full white.
- Use the single button-primary pill (#EBEBEB on #070707) for the one main action in a section. Everything else is link-arrow.
- Use letter spacing −0.5px on all text, and −6 to −7px on the display sizes.
- Use dotted rules between list rows and solid hairlines above section headers.
- Add an accent or brand colour, gradients on UI, or drop shadows.
- Use pure #000000 for the background or a grey for muted text. Use white with alpha.
- Use a second typeface, uppercase labels, or weights above 600.
- Round anything beyond the scale: 10px cards, 20px split cards, 50px work images, 60px pills.
- Put ink-faint (40%) on anything under 40px. It only passes contrast at large sizes.
- Animate for longer than 500ms, or use bounce or elastic easing.

Pick a file to see what it’s for and where it goes.
What it is
The whole design system in one markdown file, written for AI: every color, type style, spacing value, component and motion rule, plus do's, don'ts and a ready prompt.
Best for
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/altrum.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
Every token as data, in the W3C Design Tokens format: colors with their roles, type styles, radius, spacing, and component tokens that point at them.
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
sourceat it to generate tokens for any platform - In code, import it like any JSON file
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.
Best for
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
What it is
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:
color: var(--color-ink) - Change a token once and every place that uses it follows
