flowmanceSleeks X Design System
Sleeks X is a loud, poster-like creative agency site. It is pure black, set entirely in Plus Jakarta Sans semibold, with one hot orange-red (#EC4520) for actions, icon tiles and testimonial cards. The photography is warm and staged: orange backdrops, white walls with plant shadows, products floating in light. It feels like a design studio showing off its craft.
Four signatures make it recognisable:
- The selection-box hero. Three stacked words (Digital / Creative / Agency) at 150px with −5px tracking, centred. The middle word sits inside a thin white frame with square handles at each corner, like a selected text layer in Figma, with a hand-drawn cursor arrow pointing at it.
- Orange-red as the only colour. #EC4520 fills the main button, the service icon tiles (about 80px) and the testimonial cards. Everything else is black, near-black panels and white.
- Rotating project names. Along the bottom of the work images (20px up), project titles (Pellente commodo, Aenean tellus) slide past at 66px with mix-blend-mode: difference, so they invert over light and dark photos.
- Corner-anchored nav. There is no nav bar. A logo and a vertical list of links sit top-left; Cart [0] and the email hello@sleekX.io sit top-right.
Sleeks X is dark-only.

Do’s and don’ts
- Keep the page pure black #000000 with #121212 cards and one #222222 band.
- Use #EC4520 for the main button, icon tiles and testimonial cards only.
- Set display type in Plus Jakarta Sans 500–600 at 70–150px, with −5px tracking on the hero.
- Keep body text at 17px weight 600 in #F1F1F7.
- Use 5px radius on buttons and inputs and keep photos and cards square.
- Underline nav links with a 2px white line that grows on hover.
- Add a second accent (the unused #4353FF blue or #FE0000 red).
- Put text below 17px bold on #EC4520: white on orange-red is about 3.9:1, so keep button and card text at 17px+ weight 600–700.
- Use grey for body text on black; hierarchy comes from size.
- Add drop shadows, gradients or rounded photos.
- Use pill buttons; the buttons are 5–7px rectangles.
- Build a filled nav bar; links float in the corners.

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/sleeks.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
