flowmanceLeuven Design System
Leuven is a bright, playful agency site built from two hard contrasts: a white hero washed with a soft pink glow, and near-black content bands that slide up over it. One candy pink, #FC98B9, does all the accent work: the button, the service tags, the backgrounds of every work card and the full-screen menu. The type is Inter Tight 600 throughout, set large and plain, with no tracking tricks.
Four signatures make it recognisable:
- Two-tone lead sentences. A lead line starts in full ink and finishes in a quieter grey: In the realm of Webflow templates, Lèuven is a frontrunner, (black) championing designs that users love. (#777777); Advanced professional (white) service solutions. (white, dimmed).
- Pink everywhere, one pink. #FC98B9 fills the Get in touch button, the three service tags, the work-card backgrounds and the overlay menu. The three service tags each have a different corner: square, a full 50px pill, and a 30px 0px leaf.
- The white bar and the sticky hero. A fixed 110px nav (social icons left, the Lèuven wordmark centred, a two-line hamburger right) sits on white. The hero is position: sticky; top: 0, so the black sections scroll up and cover it.
- Glossy 3D renders on flat pink. A pink toy brick, a glass tube, a fuzzy sphere, an iridescent disc: soft-lit 3D objects floating on a flat #FC98B9 field, never photographs of people.

Do’s and don’ts
- Put content on canvas #060609 and keep the hero and nav on white #FFFFFF.
- Use #FC98B9 for every accent: the button, service tags, work-card fields and the overlay menu, always with #060609 text.
- Split lead sentences into a full-ink half and a muted half (title-lg, 30px/600).
- Keep work cards and images square-cornered on a flat pink field, 2 per row with a 30px gap.
- Use the 1100ms outQuint skew reveal for big headings and the 300–400ms text roll for buttons.
- Set paragraphs at ink-muted (white at 70%) on dark and #777777 for the muted half on white.
- Add a second accent colour, gradients on buttons, or shadows on cards.
- Put white text on #FC98B9 at small sizes; the work-card ticker is the only white-on-pink text, at 60px.
- Round work cards or images, or use more than the measured radii (5, 6, 8, 30 leaf, 50 pill).
- Use Hubotsans or any second family; Inter Tight 500/600 covers everything.
- Use uppercase for headlines; keep it for LEARN MORE, footer tags and stats.
- Use photography of people or offices; Leuven's images are 3D object renders.

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/leuven.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

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
