X (formerly Twitter)

# X (formerly Twitter) — Style Reference
> High-contrast information stream

**Theme:** light

**Site:** https://create.video

X (formerly Twitter) employs a high-contrast, functionally driven design system built on a monochrome base with a singular, vivid blue accent. Content takes precedence, rendered against crisp white and subtle gray surfaces, defined by thin borders and minimal elevation. Typography is compact and precise, maintaining a dense information flow, while rounded corners provide a subtle approachability to functional elements like buttons and cards.

## Tokens — Colors

| Name | Value | Token | Role |
|------|------|------|------|
| Puck Blue | `#1d9bf0` | `--color-puck-blue` | Primary action background, interactive icons, active links, and brand accents. This color defines interactive states |
| Midnight Ink | `#000000` | `--color-midnight-ink` | Primary text, strong headings, critical borders, and UI elements requiring highest contrast |
| Canvas White | `#ffffff` | `--color-canvas-white` | Page backgrounds, card surfaces, and primary button text |
| Slate Gray | `#536471` | `--color-slate-gray` | Muted captions, helper text, and de-emphasized UI labels. Do not promote it to the primary CTA color |
| Mist | `#eff3f4` | `--color-mist` | Subtle background for UI elements, light button backgrounds, and card borders |
| Border Silver | `#cfd9de` | `--color-border-silver` | Hairline borders, subtle dividers, and inactive form elements |
| Near Black | `#0f1419` | `--color-near-black` | Body text for slightly softer contrast than Midnight Ink, and secondary interactive text |
| Whisper Gray | `#e0e4e7` | `--color-whisper-gray` | Light supporting surface for subtle backgrounds and section separation. Do not promote it to the primary CTA color |
| Shadowed Button | `#4b4f53` | `--color-shadowed-button` | Background for subtle, low-prominence buttons |
| Muted Navigation Text | `#829aab` | `--color-muted-navigation-text` | Inactive navigation text |

## Tokens — Typography

### Times
- **Substitute:** Georgia
- **Weights:** 400, 700
- **Sizes:** 15px
- **Line height:** 1.2
- **Role:** Fallback serif font used sparingly, primarily in system-level or legacy contexts. Its presence suggests a system font dependency or specific legacy content.

### TwitterChirp
- **Substitute:** Inter
- **Weights:** 400, 500, 700, 800
- **Sizes:** 11px, 13px, 14px, 15px, 20px, 23px
- **Line height:** 0.8, 1.09, 1.14, 1.2, 1.22, 1.23, 1.33
- **Role:** The primary brand typeface, characterized by its range of weights for flexible information hierarchy. Used for almost all UI text, headings, and body content, especially for ensuring consistent brand voice beyond system fonts.

## Tokens — Type Scale

Major Third (1.25) from 11px base.

| Role | Size | Line height | Letter spacing |
|------|------|------|------|
| caption | 11px | 1.23 | — |
| body-lg | 15px | 1.2 | — |
| heading | 20px | 1.09 | — |
| display | 23px | 0.8 | — |

## Tokens — Spacing

- **Max width:** 1070px
- **Section gap:** 40px
- **Card padding:** 16px
- **Element gap:** 4px

## Tokens — Radius

- **Buttons:** 9999px
- **Cards:** 16px
- **avatars:** 9999px
- **links:** 9999px
- **other:** 4px

## Tokens — Elevation

- **Button:** `rgba(101, 119, 134, 0.2) 0px 0px 8px 0px, rgba(101, 119, 134, 0.25) 0px 1px 3px 1px`

## Layout

The page structure follows a max-width contained model of 1070px, with content centered. The hero section is characterized by a prominent user banner, followed by a profile header and a tabbed navigation. Content sections (feed items) flow vertically, each acting as a distinct card with internal padding. A sticky global navigation bar is present at the bottom of the viewport, providing persistent access to primary actions. The layout is dense, prioritizing information display with compact vertical rhythm, rather than spacious arrangements.

## Imagery

This system primarily uses embedded media (videos, images) and user avatars, often unstyled or with default system treatments. Product screenshots and user-generated content are showcased directly. Icons are flat, monochrome, and filled, primarily in Slate Gray (#536471) or Puck Blue (#1d9bf0) for functional indicators. The density of imagery is high, with media often taking up significant visual space within the content stream, contributing to an information-rich visual experience rather than a decorative one.

## Guidelines

### Do

- Use Midnight Ink (#000000) for all primary text and headings to ensure maximum contrast.
- Apply Puck Blue (#1d9bf0) exclusively for primary action buttons, active states, and brand iconography.
- Utilize 9999px border-radius for all interactive buttons, profile avatars, and social links to maintain a fluid, rounded aesthetic.
- Maintain a clear visual hierarchy with Canvas White (#ffffff) for primary content surfaces and Mist (#eff3f4) for subtle background distinctions.
- Enforce a base unit of 4px for all spacing decisions, translating to common increments like 4px, 8px, 12px, and 16px for clear rhythm.
- Employ the TwitterChirp font for all UI elements, utilizing its varying weights (400, 500, 700, 800) to indicate hierarchy without size changes where appropriate.
- Frame content within a pageMaxWidth of 1070px for optimal readability and balanced composition on larger screens.

### Don't

- Do not introduce new chromatic colors; adhere strictly to the Puck Blue (#1d9bf0) as the sole accent color.
- Avoid heavy shadows or gradients; the system prefers subtle elevation with Whisper Gray (#e0e4e7) or thin Border Silver (#cfd9de) outlines.
- Do not deviate from the specified font sizes and line heights for TwitterChirp to preserve the compact and high-density information display.
- Never use Times or any other serif font for primary UI text; it is reserved for system fallback or specific legacy contexts.
- Avoid applying large, decorative radii to content cards unless specifically defined, maintaining a 16px radius for standard content blocks.
- Do not cluster elements excessively; ensure a minimum elementGap of 4px to maintain visual breathing room.
- Resist using bold headlines universally; instead, leverage TwitterChirp's range of weights and the designated type scale to create nuanced visual hierarchy.
