1. Visual Theme & Atmosphere

Cursor's website is a study in warm minimalism meets code-editor elegance. The entire experience is built on a warm off-white canvas (#f2f1ed) with dark warm-brown text (#26251e) -- not pure black, not neutral gray, but a deeply warm near-black with a yellowish undertone that evokes old paper, ink, and craft. This warmth permeates every surface: backgrounds lean toward cream (#e6e5e0, #ebeae5), borders dissolve into transparent warm overlays using oklab color space, and even the error state (#cf2d56) carries warmth rather than clinical red. The result feels more like a premium print publication than a tech website.

The custom CursorGothic font is the typographic signature -- a gothic sans-serif with aggressive negative letter-spacing at display sizes (-2.16px at 72px) that creates a compressed, engineered feel. As a secondary voice, the jjannon serif font (with OpenType "cswh" contextual swash alternates) provides literary counterpoint for body copy and editorial passages. The monospace voice comes from berkeleyMono, a refined coding font that connects the marketing site to Cursor's core identity as a code editor. This three-font system (gothic display, serif body, mono code) gives Cursor one of the most typographically rich palettes in developer tooling.

The border system is particularly distinctive -- Cursor uses oklab() color space for border colors, applying warm brown at various alpha levels (0.1, 0.2, 0.55) to create borders that feel organic rather than mechanical. The signature border color oklab(0.263084 -0.00230259 0.0124794 / 0.1) is not a simple rgba value but a perceptually uniform color that maintains visual consistency across different backgrounds.

Key Characteristics:

  • CursorGothic with aggressive negative letter-spacing (-2.16px at 72px, -0.72px at 36px) for compressed display headings
  • jjannon serif for body text with OpenType "cswh" (contextual swash alternates)
  • berkeleyMono for code and technical labels
  • Warm off-white background (#f2f1ed) instead of pure white -- the entire system is warm-shifted
  • Primary text color #26251e (warm near-black with yellow undertone)
  • Accent orange #f54e00 for brand highlight and links
  • oklab-space borders at various alpha levels for perceptually uniform edge treatment
  • Pill-shaped elements with extreme radius (33.5M px, effectively full-pill)
  • 8px base spacing system with fine-grained sub-8px increments (1.5px, 2px, 2.5px, 3px, 4px, 5px, 6px)

2. Color Palette & Roles

Primary

  • Cursor Dark (#26251e): Primary text, headings, dark UI surfaces. A warm near-black with distinct yellow-brown undertone -- the defining color of the system.
  • Cursor Cream (#f2f1ed): Page background, primary surface. Not white but a warm cream that sets the entire warm tone.
  • Cursor Light (#e6e5e0): Secondary surface, button backgrounds, card fills. A slightly warmer, slightly darker cream.
  • Pure White (#ffffff): Used sparingly for maximum contrast elements and specific surface highlights.
  • True Black (#000000): Minimal use, specific code/console contexts.

Accent

  • Cursor Orange (#f54e00): Brand accent, --color-accent. A vibrant red-orange used for primary CTAs, active links, and brand moments. Warm and urgent.
  • Gold (#c08532): Secondary accent, warm gold for premium or highlighted contexts.

Semantic

  • Error (#cf2d56): --color-error. A warm crimson-rose rather than cold red.
  • Success (#1f8a65): --color-success. A muted teal-green, warm-shifted.

Timeline / Feature Colors

  • Thinking (#dfa88f): Warm peach for "thinking" state in AI timeline.

Principles

  • Gothic compression for impact: CursorGothic at display sizes uses -2.16px letter-spacing at 72px, progressively relaxing: -0.72px at 36px, -0.325px at 26px, -0.11px at 22px, normal at 16px and below. The tracking creates a sense of precision engineering.
  • Serif for soul: jjannon provides literary warmth. The "cswh" feature adds contextual swash alternates that give body text a calligraphic quality.
  • Three typographic voices: Gothic (display/UI), serif (editorial/body), mono (code/technical). Each serves a distinct communication purpose.
  • Weight restraint: CursorGothic uses weight 400 almost exclusively, relying on size and tracking for hierarchy rather than weight. System-ui components use 500-700 for functional emphasis.

AI Timeline

  • Vertical timeline showing AI operations: thinking (peach), grep (sage), read (blue), edit (lavender)
  • Each step uses its semantic color with matching text
  • Connected with vertical lines
  • Core visual metaphor for Cursor's AI-first coding experience

5. Layout Principles

Spacing System

  • Base unit: 8px
  • Fine scale: 1.5px, 2px, 2.5px, 3px, 4px, 5px, 6px (sub-8px for micro-adjustments)
  • Standard scale: 8px, 10px, 12px, 14px (derived from extraction)
  • Extended scale (inferred): 16px, 24px, 32px, 48px, 64px, 96px
  • Notable: fine-grained sub-8px increments for precise icon/text alignment

Grid & Container

  • Max content width: approximately 1200px
  • Hero: centered single-column with generous top padding (80-120px)
  • Feature sections: 2-3 column grids for cards and features
  • Full-width sections with warm cream or slightly darker backgrounds
  • Sidebar layouts for documentation and settings pages

Whitespace Philosophy

  • Warm negative space: The cream background means whitespace has warmth and texture, unlike cold white minimalism. Large empty areas feel cozy rather than clinical.
  • Compressed text, open layout: Aggressive negative letter-spacing on CursorGothic headlines is balanced by generous surrounding margins. Text is dense; space around it breathes.
  • Section variation: Alternating surface tones (cream → lighter cream → cream) create subtle section differentiation without harsh boundaries.

Border Radius Scale

  • Micro (1.5px): Fine detail elements
  • Small (2px): Inline elements, code spans
  • Medium (3px): Small containers, inline badges
  • Standard (4px): Cards, images, compact buttons
  • Comfortable (8px): Primary buttons, cards, menus
  • Featured (10px): Larger containers, featured cards
  • Full Pill (33.5M px / 9999px): Pill buttons, tags, badges

6. Depth & Elevation

Elevated Card (Level 3)rgba(0,0,0,0.14) 0px 28px 70px, rgba(0,0,0,0.1) 0px 14px 32px, oklab ringModals, popovers, elevated cards
Focusrgba(0,0,0,0.1) 0px 4px 12px on button focusInteractive focus feedback

Shadow Philosophy: Cursor's depth system is built around two ideas. First, borders use perceptually uniform oklab color space rather than rgba, ensuring warm brown borders look consistent across different background tones. Second, elevation shadows use dramatically large blur values (28px, 70px) with moderate opacity (0.14, 0.1), creating a diffused, atmospheric lift rather than hard-edged drop shadows. Cards don't feel like they float above the page -- they feel like the page has gently opened a space for them.

Decorative Depth

  • Warm cream surface variations create subtle tonal depth without shadows
  • oklab borders at 10% and 20% create a spectrum of edge definition
  • No harsh divider lines -- section separation through background tone shifts and spacing

7. Interaction & Motion

Hover States

  • Buttons: text color shifts to --color-error (#cf2d56) on hover -- a distinctive warm crimson that signals interactivity
  • Links: color shift to accent orange (#f54e00) or underline decoration with rgba(38, 37, 30, 0.4)
  • Cards: shadow intensification on hover (ambient → elevated)

Focus States

  • Shadow-based focus: rgba(0,0,0,0.1) 0px 4px 12px for depth-based focus indication
  • Border focus: oklab(0.263 / 0.2) (20% border) for input/form focus
  • Consistent warm tone in all focus states -- no cold blue focus rings

Transitions

  • Color transitions: 150ms ease for text/background color changes
  • Shadow transitions: 200ms ease for elevation changes
  • Transform: subtle scale or translate for interactive feedback

8. Responsive Behavior

Breakpoints

NameWidthKey Changes
Mobile<600pxSingle column, reduced padding, stacked navigation
Tablet Small600-768px2-column grids begin
Tablet768-900pxExpanded card grids, sidebar appears
Desktop Small900-1279pxFull layout forming
Desktop>1279pxFull layout, maximum content width

Touch Targets

  • Buttons use comfortable padding (6px-14px vertical, 8px-14px horizontal)
  • Pill buttons maintain tap-friendly sizing with 3px-10px padding
  • Navigation links at 14px with adequate spacing for touch

Collapsing Strategy

  • Hero: 72px CursorGothic → 36px → 26px on smaller screens, maintaining proportional letter-spacing
  • Navigation: horizontal links → hamburger menu on mobile
  • Feature cards: 3-column → 2-column → single column stacked
  • Code editor screenshots: maintain aspect ratio, may shrink with border treatment preserved
  • Timeline visualization: horizontal → vertical stacking
  • Section spacing: 80px+ → 48px → 32px on mobile

Image Behavior

  • Editor screenshots maintain warm border treatment at all sizes
  • AI timeline adapts from horizontal to vertical layout
  • Product screenshots use responsive images with consistent border radius
  • Full-width hero images scale proportionally

  • "Design an AI timeline showing four steps: Thinking (#dfa88f), Grep (#9fc9a2), Read (#9fbbe0), Edit (#c0a8dd). Each step: 14px system-ui label + 16px CursorGothic description + vertical connecting line in rgba(38,37,30,0.1)."

Iteration Guide

  1. Always use warm tones -- #f2f1ed background, #26251e text, never pure white/black for primary surfaces
  2. Letter-spacing scales with font size for CursorGothic: -2.16px at 72px, -0.72px at 36px, -0.325px at 26px, normal at 16px
  3. Use rgba(38, 37, 30, alpha) as a CSS-compatible fallback for oklab borders
  4. Three fonts, three voices: CursorGothic (display/UI), jjannon (editorial), berkeleyMono (code)
  5. Pill shapes (9999px radius) for tags and filters; 8px radius for primary buttons and cards
  6. Hover states use #cf2d56 text color -- the warm crimson shift is a signature interaction
  7. Shadows use large blur values (28px, 70px) for diffused atmospheric depth
  8. The sub-8px spacing scale (1.5, 2, 2.5, 3, 4, 5, 6px) is critical for icon/text micro-alignment
