flowmanceConstructo Design System
Constructo is a light, practical construction-company site. It reads like a project board pinned over a blueprint: thin grey architectural line drawings on a pale blue wash, tall condensed black uppercase headlines, plain grey body copy and square orange buttons. Colour is rationed: one safety orange for actions and highlights, black for type, and the photography (timber, scaffolding, cranes, concrete) supplies the rest.
Four signatures make it recognisable:
- The orange brush underline. One word in each big headline sits on a hand-drawn orange stroke: FOR BETTER FUTURE. underlines BETTER, OUR AREAS OF EXPERTISE underlines EXPERTISE.
- The slanted header tab. The fixed navigation is a white 90px bar, 1200px wide, whose left and right ends are cut at an angle by 90px CSS border triangles, so it hangs from the top of the viewport like a trapezoid tab.
- Condensed uppercase Oswald against Satoshi. Headings, labels, buttons, menu and footer links are Oswald in uppercase; only the small blog category links switch to Satoshi. Every paragraph is Satoshi in dim grey #54565A, in sentence case.
- The black project grid. Projects sit edge to edge on a black band, three across with 12px gaps, each photo captioned by a white Oswald name and a grey Satoshi category on the same line.

Do’s and don’ts
- Set headings, labels, buttons, menu and footer links in Oswald uppercase, and every paragraph in Satoshi 19/500 at ink-muted #54565A.
- Put the orange brush stroke under one key word of each big headline, and only one.
- Use primary #E56033 square buttons (3px radius, 56px tall) that turn black #000000 on hover.
- Alternate white sections with the #EEF4FC wash and full-bleed black bands.
- Keep photos square-cornered and cards at 10px with a 1px #90949B-25% border instead of a shadow.
- Keep the header as the slanted white tab, with only the logo and MENU.
- Add a second accent colour; #FF9302 and #B1B7C0 exist in the variables but aren't part of the look.
- Use Playfair Display or any serif, even though the page loads it.
- Put white text on orange below 14px or in a weight under 500; #FFFFFF on #E56033 is only about 3.4:1, so keep button labels uppercase, 14px+ and weight 500.
- Use ink-subtle #90949B for paragraphs. It is about 3:1 on white, so keep it for 14px+ labels and categories.
- Add drop shadows, gradients on buttons or rounded photos.
- Track headlines tighter or looser than 0, or set them in sentence case.

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/constructo.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

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

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:
