Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Spartan-AI’s logo, name, pictures or text.

### How accurate are the values?

Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.

# Spartan-AI Design System

## Overview

Spartan-AI describes itself as: “Build a world-class digital presence with the Spartan AI template—a premium Framer ecosystem designed specifically for AI research labs, neural engineering firms, and high-end tech agencies.” The interface is light, built on **Mist (#F0F0F0)** with **Charcoal (#1A1A1A)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **Inter Display** and **Inter**, with **IBM Plex Mono** for code. Headlines run large with tight negative tracking; body text is 14px. The surface language is flat. Corners are mostly 20px.

Measured from [spartanai.framer.website](https://spartanai.framer.website/) on November 6, 2026 at 1440×900 and 390×844 from 372 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 9 roles.

- **Mist (#F0F0F0):** Page background, seen 16 times. Token `background`.
- **Charcoal (#1A1A1A):** Primary text and headings, seen 47 times. Token `on-surface`.
- **White (#FFFFFF):** Raised areas one step from the page, seen 8 times. Token `surface-container-low`.
- **White 10% (#FFFFFF1A):** Translucent fill for cards and controls, seen 4 times. Token `overlay`.
- **Near Black 5% (#0000000D):** Stronger translucent fill, seen 1 time. Token `overlay-strong`.
- **Charcoal 6% (#1A1A1A0F):** Borders and dividers, seen 5 times. Token `outline`.
- **Charcoal 10% (#1A1A1A1A):** Secondary dividers, seen 3 times. Token `outline-variant`.
- **Charcoal (#1A1A1A):** Primary buttons and calls to action, seen 66 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.

## Typography

**Inter Display**, **Inter**, **sans-serif** and **IBM Plex Mono** (monospace) share the interface. Fallback stack: `Inter Display, Inter Display Placeholder, sans-serif`. Other loaded fonts: Geist Mono, Jaini.

- **headline-display:** Inter Display 200px at weight 700, line height 1.1, tracking -0.04em (128px on mobile). Page title (h1).
- **headline-lg:** Inter Display 70px at weight 500, line height 1.1, tracking -0.04em (45px on mobile). Section headings (h2).
- **headline-md:** Inter Display 56px at weight 500, line height 1.07, tracking -0.036em. Sub-section headings.
- **headline-sm:** Inter Display 54px at weight 500, line height 1.1, tracking -0.04em. Card and feature titles.
- **title-lg:** Inter 43px at weight 400, line height 1, tracking -0.047em. Small titles.
- **body-md:** Inter Display 14px at weight 300, line height 1.5, tracking 0.02em. Body text.
- **body-lg:** Inter Display 16px at weight 300, line height 1.5, tracking 0.02em. Lead paragraphs.
- **body-sm:** Inter Display 12px at weight 300, line height 1.4, tracking 0.01em. Secondary and small text.
- **label-md:** sans-serif 12px at weight 400. Buttons, navigation and labels.
- **code:** IBM Plex Mono 13px at weight 500, line height 1.6. Code and technical values.

## Layout

Spacing does not follow a strict grid: 24% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3px, sm 6px, md 10px, lg 20px.
- **Gaps:** 10px is the most common gap in flex and grid layouts.
- **Page margin:** 12px on each side of full-width sections.
- **Breakpoints:** 809px, 809.98px, 810px, 1199px, 1199.98px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#FFFFFF) and #1A1A1A0F borders.

## Shapes

Most elements use 20px corners. Measured radii, most used first:

- **lg (20px):** 82 elements.
- **md (16px):** 24 elements.
- **sm (12px):** 20 elements.
- **xs (6px):** 16 elements.
- **xl (40px):** 8 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Start Build”):** #1A1A1A fill, #FFFFFF text, 12px/400, 16px radius, padding 3px 24px 3px 3px.
- **button-primary-hover:** background #1A1A1A, text #1A1A1A on hover.
- **button-ghost (“Subscribe”):** transparent fill, #000000 text, 12px/400, 10px radius, padding 0px.
- **input-field (“jane@framer.com”):** transparent fill, #FFFFFF text, 16px/400, padding 0px.
- **link:** transparent fill, #1A1A1A text, padding 0px.

## Do's and Don'ts

- Do use #F0F0F0 for the page and lift surfaces in small steps: #FFFFFF.
- Do let contrast carry emphasis; primary actions use #1A1A1A on #F0F0F0.
- Do set headlines in Inter Display with tight tracking (-0.04em).
- Do reuse the measured spacing steps (6px, 10px, 20px).
- Do use 20px corners on most elements; larger surfaces also use 16px, 12px and 6px.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond Inter Display, Inter, sans-serif and IBM Plex Mono.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.1s.

## Motion

Interface transitions are quick: 0.1s.

- **Easing:** `ease`.
