# airbnb.com

## Overview

Airbnb | Vacation rentals, cabins, beach houses, & more: Get an Airbnb for every kind of trip → 8 million vacation rentals → 2 million Guest Favorites → 220+ countries and regions worldwide

Pill-shaped controls, layered shadows for depth, restrained display type at 28px / 700, a single red accent on neutrals. The site ships in light mode by default. Measured from 1625 rendered elements at 1440px wide on 2026-09-28.

Reference screenshots live beside this file; look at them before writing any layout, they carry the composition, density and image treatment that tokens cannot:

- `screenshots/desktop-1440-fold.png`: Desktop 1440, above the fold
- `screenshots/desktop-1440-full.jpg`: Desktop 1440, full page
- `screenshots/laptop-1024-fold.png`: Laptop 1024, above the fold
- `screenshots/tablet-768-fold.png`: Tablet 768, above the fold
- `screenshots/phone-390-fold.png`: Phone 390, above the fold
- `screenshots/phone-390-full.jpg`: Phone 390, full page

## Colors

| Token | Value | Use |
| --- | --- | --- |
| background | `#ffffff` | Page background |
| surface | `#dddddd` | Cards, panels, raised or recessed surfaces |
| surface-2 | `#f2f2f2` | Secondary surface |
| foreground | `#222222` | Primary text |
| muted-foreground | `#6c6c6c` | Secondary text, captions |
| primary | `#da1249` | Accent: primary buttons, links, focus |
| on-primary | `#ffffff` | Text on the accent |
| border | `#ffffff` | Hairlines, dividers, input borders |

Full painted palette by area (largest first): `#ffffff`, `#dddddd`, `#f2f2f2`, `#da1249`.

Gradients in use: `linear-gradient(rgb(255, 255, 255) 39.9%, rgb(248, 248, 248) 100%)`.

The accent `#da1249` is used sparingly: primary buttons, links and focus rings. Everything else stays neutral.

## Typography

## Responsive Behavior

| Viewport | Content width | Gutter | Body | H1 | Header | Hero | Grids | Buttons |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| desktop 1440px | fluid | 50px | 14px | 28px, 0 lines, start | 96px, hamburger (Main navigation menu), 2 CTA | media below text | 3→3 col; 5→3 col; 2→1 col | content-width |
| laptop 1024px | fluid | 34px | 14px | 28px, 0 lines, start | 80px, hamburger (Main navigation menu), 2 CTA | media below text | 3→3 col; 4→3 col; 2→2 col | content-width |
| tablet 768px | fluid | 26px | 14px | 28px, 0 lines, start | 80px, hamburger (Main navigation menu), 2 CTA | text only | 4→3 col; 2→2 col; 2→1 col | content-width |
| phone 390px | fluid | 26px | 14px | 28px, 0 lines, start | 125px, 3 links | media below text | 2→1 col; 2→1 col; 2→1 col | 1 full-width |

- H1 goes 28px → 28px (100%), 0 → 0 lines.
- Nav never collapses to a hamburger (3 links still visible at 390px).
- Body text stays 14px at every width.
- Phone side gutter 26px.
- 1 buttons stretch full-width on phones.

## Interaction & Motion

80 elements carry transitions; typical 0.25s with cubic-bezier(0.2, 0, 0, 1), mostly on transform, box-shadow, background-color. 1 running keyframe animations (kf-h0qfv9 0.15s 1).

- Hover on button-primary: no visible change; cursor pointer; transition transform | 0.25s | cubic-bezier(0.2, 0, 0, 1).
- Hover on button-secondary: no visible change; cursor pointer; transition transform | 0.25s | cubic-bezier(0.2, 0, 0, 1).
- Hover on nav-link ("All"): no visible change; cursor pointer.
- Hover on input: no visible change; cursor text.
- Focus on button-primary: no visible focus style measured (may rely on :focus-visible with keyboard only).
- Focus on input: no visible focus style measured (may rely on :focus-visible with keyboard only).
- Tooltip triggers exist (4 × aria-describedby, 2 × title) but none opened on hover in the first viewport; title attributes fall back to the browser's native tooltip.
- Hover/click menus: below the trigger, 1352px gap, shifted left; transparent, radius 0px, padding 0px 0px, shadow none; appears instantly (no fade); stays open after the pointer leaves (click-away or hover-intent grace).
- 14 sizable elements sit at opacity 0 before scrolling: scroll-reveal animations are in use (reveal on enter, fade + rise is the usual recipe).

Full detail (every overlay, table, form, scroll and text rule measured) is in `BEHAVIOR.md`; raw evidence in `evidence.json`.

## Do's and Don'ts

- Do use 4px multiples for every padding, margin and gap; the site does not use odd values.
- Do reserve `#da1249` for actions and focus; never paint large areas with it.
- Do keep body text at 14px in Airbnb Cereal VF.
- Do match corner radii per element class (buttons 9999px, cards 0px); do not pick one radius for everything.
- Do use the measured shadows above; do not invent heavier ones.
- Don't substitute a different accent hue or introduce gradients that are not listed above.
- Don't rebuild from the tokens alone; open the screenshots for composition, density and image treatment.
