# Later Design System

## Overview

Later describes itself as: “Influencer marketing built for creators and trusted by brands. Run campaigns, manage social media, and track performance with AI-powered insights.” The interface is light, built on **White (#FFFFFF)** with **Near Black (#000000)** text, and **Vivid Red (#FE3F00)** as the main accent.

Type is set in **Super X sans Display** and **Inter Tight**. Headlines run large; body text is 14px. The surface language is flat. Corners are square.

Measured from [later.com](https://later.com/) on October 21, 2026 at 1440×900 and 390×844 from 343 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 9 roles.

- **White (#FFFFFF):** Page background. Token `background`, CSS `--color-white`.
- **Near Black (#000000):** Primary text and headings, seen 28 times. Token `on-surface`, CSS `--tiktok`.
- **Snow (#FEFCFB):** Raised areas one step from the page, seen 2 times. Token `surface-container-low`.
- **Warm Mist (#F8F2EA):** Cards and panels, seen 6 times. Token `surface-container`, CSS `--lib`.
- **Warm Mist (#F8F2EA):** Borders and dividers, seen 8 times. Token `outline`, CSS `--lib`.
- **Snow (#FEFCFB):** Secondary dividers, seen 1 time. Token `outline-variant`.
- **Vivid Red (#FE3F00):** Primary buttons and calls to action, seen 7 times. Token `primary`.
- **Warm Mist (#F8F2EA):** Text and icons on primary. Token `on-primary`.
- **Violet (#5124C1):** Accent, seen 8 times. Token `secondary`.

## Typography

**Super X sans Display** and **Inter Tight** share the interface. Fallback stack: `Super X sans Display, Helvetica Neue, Helvetica, Arial`.

## Layout

Spacing follows a 4px grid: 94% of measured gaps and paddings are multiples of 4px.

- **Scale:** xs 4px, sm 8px, md 12px, lg 24px, xl 40px.
- **Sections:** 70px vertical padding between major sections.
- **Gaps:** 32px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1440px.
- **Page margin:** 40px on each side of full-width sections.
- **Breakpoints:** 500px, 501px, 799px, 800px, 991px, 992px, 1199px, 1200px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#FEFCFB → #F8F2EA) and #F8F2EA borders.

## Shapes

Corners are square. Measured radii, most used first:

- **none (0px):** measured.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Start your campaign”):** #FE3F00 fill, #F8F2EA text, 16px/400, padding 12px 40px 12px 24px, border 2px solid #FE3F00.
- **button-secondary (“Earn as a creator”):** #000000 fill, #000000 text, 16px/400, padding 12px 40px 12px 24px, border 2px solid #000000.
- **button-tertiary (“Get Later”):** #000000 fill, #F8F2EA text, 16px/400, padding 12px 40px 12px 24px, border 2px solid #000000.
- **button-ghost (“Sign in”):** transparent fill, #000000 text, 16px/400, padding 0px 8px.
- **input-field (“Enter your email address”):** transparent fill, #FEFCFB text, 16px/400, padding 8px 16px, border 1px solid #FEFCFB, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 3.2px, rgba(0, 0, 0, 0) 0px 0px 0px 6.4px`.
- **link:** transparent fill, #F9F3ECCC text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #FEFCFB, #F8F2EA.
- Do reserve #FE3F00 for primary actions and key highlights.
- Do keep spacing on the 4px grid.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond Super X sans Display and Inter Tight.
- Don't use #FE3F00 for large backgrounds or body text.
- Don't make interface transitions slower than 0.000001s.

## Motion

Interface transitions are quick: 1e-06s.

- **Easing:** `ease`.
