# Tailwind CSS

> Extracted from [https://tailwindcss.com/](https://tailwindcss.com/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Tailwind CSS uses a light canvas (#FFFFFF) with a palette led by #00A6F4. Type is set in **Inter** (display + body), **Plex Mono** (mono), with 14px body text. Layout: 1360px container, none-detected navigation, 5 sections. Built with next.js, tailwind, shadcn/ui, mintlify, google-tag-manager, vercel, cloudflare.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#FFFFFF` | 1 0 0 | bg | 82.8% | `--color-white` |
| `on-surface` | `#030712` | 0.13 0.028 261.7 | text | 5.5% | `--color-gray-950` |
| `outline` | `#0307120D` (on bg `#F2F3F3`) | 0.13 0.028 261.7 | border | 2.7% | — |
| `surface` | `#FFFFFF1A` (on bg `#FFFFFF`) | 1 0 39 | surface | 2.9% | — |
| `on-surface-variant` | `#4A5565` | 0.446 0.03 256.8 | muted | 1.2% | `--color-gray-600` |
| `primary` | `#00A6F4` | 0.691 0.16 240.6 | accent | 0.06% | `--color-sky-500` |
| `color-7` | `#0000010D` (on bg `#F2F2F2`) | 0.052 0.001 258.7 | other | 2.0% | — |
| `color-8` | `#0000000D` (on bg `#F2F2F2`) | 0 0 0 | other | 0.80% | — |
| `black` | `#000000` | 0 0 0 | other | 0.08% | `--color-black` |

Sparse chromatic highlights (not accents): `#F6339A` (`--color-pink-500`), `#E60076` (`--color-pink-600`), `#00598A` (`--color-sky-800`).

Contrast: text on background 20.13:1, muted text 7.56:1, accent 2.71:1.

Gradients in use: `radial-gradient(oklab(0.129999 -0.00404751 -0.027702 / 0.05) 1px, rgba(0, 0, 0, 0) 0px)`; `repeating-linear-gradient(315deg, oklab(0 0 0 / 0.05) 0px, oklab(0 0 0 / 0.05) 1px, rgba(0, 0, 0, 0) 0px, rgba(0, 0, 0, 0) 50%)`.

The site responds to `prefers-color-scheme: dark`; the `-dark` tokens hold the dark-mode roles.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** (CSS: `inter`) | display, body | 400, 500, 600 | 73.0% | webfont |
| **Plex Mono** (CSS: `plexMono`) | mono | 400, 500, 600 | 26.3% | webfont |

Declared in `@font-face` but not used to paint text on this page: Source, Ubuntu Mono. Don't treat these as the page's fonts.

Scale (px): 12, 13, 14, 16, 17, 18, 20, 24, 30, 36, 40, 96. Effective ratio ≈ 1.239 (close to a major third). Body 14px at line-height 2; display 96px with tracking -0.05em. Headings are sentence case. On a 390px viewport the body is 14px and display 36px.

## Layout

Spacing follows a 8px base unit; the most used steps are 4, 8, 12, 16, 24, 32, 36, 40, 64px. Sections open with about 160px of space before their first line of text. Content sits in a 1360px container on a 2-column grid. Text density 0.079 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **hero** — “Rapidly build modern websites without ever leaving your HTML.” (2846px, bg #FFFFFF)
2. **section** (2336px, bg #FFFFFF)
3. **section** — “Browse properties” (2024px, bg #FFFFFF)
4. **section** — “Ship faster and smaller.” (1006px, bg #FFFFFF)
5. **footer** — “Build whatever you want, without touching your CSS file.” (2076px, bg #FFFFFF)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`
- `rgba(0, 0, 0, 0.25) 0px 25px 50px -12px`
- `rgba(0, 0, 0, 0.1) 0px 20px 25px -5px, rgba(0, 0, 0, 0.1) 0px 8px 10px -6px`

## Shapes

Dominant corner radius 0px; radii in use: 4px, 8px, 12px, 16px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#000000`, textColor `#FFFFFF`, rounded `9999px`, padding `8px 16px`, height `40px`, fontFamily `Inter`, fontSize `14px`, fontWeight `600` (e.g. “Get started”)
- **card**: rounded `16px`, padding `28px`, backgroundColor `#FFFFFF`
- **input**: rounded `0px`, height `24px`, padding `0px 0px`

## Do's and Don'ts

- Do reserve `#00A6F4` for primary actions and highlights; it covers only 0.06% of the painted page.
- Do set body copy in Inter at 14px / 2.
- Do tighten large headlines (-0.05em at 96px).
- Don't introduce font weights beyond 400, 500, 600.
- Do keep corners at 0px for most controls, and use the larger radii only for cards and media.
- Do snap spacing to multiples of 8px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
