Airbnb UI Skills

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

When to Apply

Reference these guidelines when:

• Building light-mode interfaces

• Creating Airbnb-inspired design systems

• Implementing UIs with Inter font and 4px grid

Colors

• SHOULD use light backgrounds for primary surfaces

• MUST use #FEFEFE as page background (surface-base )

• SHOULD reduce color palette (currently 13 colors detected)

• MUST maintain text contrast ratio of at least 4.5:1 for accessibility

Semantic Tokens

Token HEX RGB Usage

surface-base

#FEFEFE rgb(254,254,254) Page background

surface-raised

#EEEBE4 rgb(238,235,228) Cards, modals, raised surfaces

surface-overlay

#D5D3D1 rgb(213,211,209) Overlays, tooltips, dropdowns

text-primary

#8F8F8F rgb(143,143,143) Headings, body text

text-2

#5C5955 rgb(92,89,85) Additional text

text-secondary

#686868 rgb(104,104,104) Secondary, muted text

border-default

#E6DECC rgb(230,222,204) Subtle borders, dividers

destructive

#E25275 rgb(226,82,117) Error states, delete actions

warning

#E6DECC rgb(230,222,204) Warning states, cautions

Typography

• MUST use Inter as primary font family

• SHOULD use single font family for consistency

• MUST use 19px / 500 for primary headings

• MUST use 15px / 400 for body text

• MUST limit font weights to: light, regular, medium

• 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 65x)

Font Sizes: 6px, 8px, 9px, 10px, 11px, 13px, 14px, 15px, 19px

Spacing

• MUST use 4px grid for spacing

• SHOULD use spacing from scale: 1px, 2px, 3px, 5px, 6px, 9px, 10px, 41px

• SHOULD use 2px 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: 11px, 12px, 13px, 14px, 28px

• SHOULD use 28px+ radius for pill-shaped elements

• MUST use 1px border width consistently

• SHOULD use 11px 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: 11px, 12px, 13px, 14px, 28px

Layout

• MUST design for 1920px base viewport width

• SHOULD use consistent element widths: 249px, 24px, 97px, 28px, 78px

• 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: 1080px

• Main Content: width: 1920px, height: 879px

Components

• MUST use 0px height for input fields

Buttons

Variant Background Text Border Height Radius

Ghost transparent #5C5955 none

Inputs

• Height: 0px

Interactive States

Focus

• MUST use 2px outline with accent color (#5E6AD2 )

• MUST use 2px outline-offset

• NEVER remove focus indicators

Hover

• Buttons (primary): lighten background by 10%

• Buttons (secondary): use #EEEBE4 background

• List items: use #EEEBE4 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
