flowmanceStructa Design System
Structa is a calm architecture and interior studio site. It feels like a printed monograph: a warm stone background (#ECEBE9), black sans-serif text with no greys, and large sunlit, slightly grainy photographs of minimal rooms and white buildings that carry all the warmth. The page alternates between full-width photo panels inset 10px from the window edge and open stone space where small images float at different heights.
Four signatures make it recognisable:
- The 10px inset. The hero video and every project panel stop 10px short of the viewport edges, so a thin stone frame runs around the photography.
- One giant line of type. Designing the world… runs across the page in Instrument Sans at 230px with −8px tracking, cropped by both edges and moved sideways by scroll.
- A Didone counter. Project panels carry a 1 / 4 counter in Antic Didone, the only serif on the page, in a dark glass chip at the top right.
- Bulleted nav. Each nav link has a small black dot before it: ● Home ● Studio ● Blog ● Contact. The logo is Structa©.
Structa is a light design with a single dark band, the brown footer.

Do’s and don’ts
- Use the #ECEBE9 stone as the page background and keep all text #000000 on it.
- Inset full-width photos 10px from the viewport edges with square corners.
- Set titles in Instrument Sans 600 in sentence case, with full stops.
- Use Antic Didone only for N / N counters in a #00000066 glass chip with a 20px blur.
- Put a 1px #FFFFFF4D rule above any text that sits on a photo.
- Use the #5C5448 brown only for the footer band and the large secondary pill.
- Add grey text colours; drop opacity on black instead (0.6, 0.5).
- Use uppercase, letter spacing on body text, or a second serif style.
- Round photos or cards; only buttons, inputs, chips and dots are rounded.
- Add drop shadows or coloured gradients.
- Use #0000008C (ink-subtle) for paragraphs; keep it for placeholders and meta at 14px and up.
- Invent hover colours for the buttons; the measured hover is a 300ms arrow nudge and underline change.

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/structa.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
