Robinhood UI Skills

Opinionated constraints for building Robinhood-style interfaces with AI agents.

When to Apply

Reference these guidelines when:

  • Building dark-mode interfaces
  • Creating Robinhood-inspired design systems
  • Implementing UIs with Inter font and 4px grid

Colors

  • MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 0
  • MUST use #000000 as page background (surface-base)
  • MUST use #B7DF2F for primary actions and focus states (accent)
  • SHOULD limit color palette to 10 distinct colors
  • MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

TokenHEXRGBUsage

surface-raised#C3FE09rgb(195,254,9)Cards, modals, raised surfaces

text-secondary#497009rgb(73,112,9)Secondary, muted text
border-default#B7DF2Frgb(183,223,47)Subtle borders, dividers
accent#B7DF2Frgb(183,223,47)Primary actions, links, focus

Typography

  • MUST use Inter as primary font family
  • SHOULD use single font family for consistency
  • MUST use 85px / 700 for primary headings
  • MUST use 14px / 400 for body text
  • SHOULD reduce font weights (currently 4 detected)
  • MUST use text-balance for headings and text-pretty for body text
  • SHOULD use tabular-nums for numeric data
  • NEVER modify letter-spacing unless explicitly requested

Typography Reference

Font Families:

  • Inter (used 13x)

Font Sizes: 11px, 14px, 17px, 18px, 85px

Spacing

  • MUST use 4px grid for spacing
  • SHOULD use spacing from scale: 4px, 5px, 6px, 12px, 13px, 14px, 17px, 19px
  • SHOULD use 4px as default gap between elements
  • NEVER use arbitrary spacing values (use design scale)
  • SHOULD maintain consistent padding within containers

Borders

  • MUST use border-radius from scale: 19px, 21px
  • SHOULD use 21px+ radius for pill-shaped elements
  • SHOULD limit border widths to: 1px, 2px
  • SHOULD use 21px as default border-radius
  • NEVER use arbitrary border-radius values (use design scale)
  • SHOULD use subtle borders (1px) for element separation

Border Radius Reference

Scale: 19px, 21px

Layout

  • MUST design for 1920px base viewport width
  • SHOULD use consistent element widths: 12px, 74px
  • SHOULD maintain text-heavy layout with clear hierarchy
  • NEVER use h-screen, use h-dvh for full viewport height
  • MUST respect safe-area-inset for fixed elements
  • SHOULD use size-* for square elements instead of w-* + h-*

Detected Layout Patterns

  • Main Content: width: 1920px, height: 1016px
  • Header: height: 64px
  • Main Content: width: 1920px, height: 608px
  • Main Content: width: 1920px, height: 1001px
  • Header: height: 63px

Components

Interactive States

Focus

  • MUST use 2px outline with accent color (#B7DF2F)
  • MUST use 2px outline-offset
  • NEVER remove focus indicators

Hover

  • Buttons (primary): lighten background by 10%
  • Buttons (secondary): use #C3FE09 background
  • List items: use #C3FE09 background

Disabled

  • MUST use opacity: 0.5
  • MUST use cursor: not-allowed

Interaction

  • MUST use an AlertDialog for destructive or irreversible actions
  • SHOULD use structural skeletons for loading states
  • MUST show errors next to where the action happens
  • NEVER block paste in input or textarea elements
  • MUST add an aria-label to icon-only buttons

Animation

  • NEVER add animation unless it is explicitly requested
  • MUST animate only compositor props (transform, opacity)
  • NEVER animate layout properties (width, height, top, left, margin, padding)
  • SHOULD use ease-out on entrance animations
  • NEVER exceed 200ms for interaction feedback
  • SHOULD respect prefers-reduced-motion

Performance

  • NEVER animate large blur() or backdrop-filter surfaces
  • NEVER apply will-change outside an active animation
  • NEVER use useEffect for anything that can be expressed as render logic
