# Linux Foundation - Education Design System

## Overview

Linux Foundation - Education describes itself as: “Gain marketable IT skills and grow your career with open source training and certifications from The Linux Foundation.” The interface is light, built on **White (#FFFFFF)** with **Near Black (#000000)** text, and **Deep Blue (#003366)** as the main accent.

Type is set in **Open Sans**. Headlines run large with tight negative tracking; body text is 18px. The surface language is flat. Corners are mostly 5px.

Measured from [training.linuxfoundation.org](https://training.linuxfoundation.org/) on November 4, 2026 at 1440×900 and 390×844 from 141 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 11 roles.

- **White (#FFFFFF):** Page background, seen 7 times. Token `background`, CSS `--nectar-extra-color-2`.
- **Near Black (#000000):** Primary text and headings, seen 6 times. Token `on-surface`.
- **Charcoal (#202020):** Secondary text, seen 3 times. Token `on-surface-variant`.
- **Slate (#555555):** Muted text and metadata, seen 6 times. Token `on-surface-muted`.
- **Slate (#777777):** Subtle text and placeholders, seen 15 times. Token `on-surface-subtle`.
- **Gray (#B6B6B6):** Borders and dividers, seen 3 times. Token `outline`.
- **Deep Blue (#003366):** Brand color on large areas. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Blue (#0077CC):** Accent in the header, seen 1 time. Token `secondary`.
- **Cyan (#0099CC):** Secondary buttons, seen 7 times. Token `tertiary`.
- **Dark Red (#790000):** Errors and destructive states, seen 2 times. Token `error`.

## Typography

**Open Sans** carries the whole interface. Fallback stack: `Open Sans`. Other loaded fonts: FontAwesome, icomoon, nectarbrands, Heebo.

- **headline-display:** Open Sans 40px at weight 900, line height 1.13, tracking -0.01em. Page title (h1).
- **headline-lg:** Open Sans 30px at weight 300, line height 1.33, tracking -0.01em (21px on mobile). Section headings (h2).
- **body-md:** Open Sans 18px at weight 400, line height 1.67, tracking -0.022em. Body text.
- **body-sm:** Open Sans 13px at weight 400, tracking -0.031em. Secondary and small text.
- **caption:** Open Sans 12px at weight 400, line height 1.83, tracking -0.033em. Captions and fine print.
- **label-md:** Open Sans 15px at weight 500, line height 1.87. Buttons, navigation and labels.
- **label-sm:** Open Sans 14px at weight 700, line height 1.3, tracking -0.029em. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 46% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 5px, md 15px, lg 32px, xl 48px.
- **Gaps:** 15px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 600px.
- **Breakpoints:** 600px, 690px, 699px, 700px, 767px, 991px, 999px, 1000px, 1024px, 1180px, 1181px, 1200px, 1300px, 1350px, 1400px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from color contrast and #B6B6B6 borders.

## Shapes

Most elements use 5px corners. Measured radii, most used first:

- **md (5px):** 64 elements.
- **sm (2px):** 4 elements.
- **lg (30px):** 4 elements.

## Components

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

- **button-primary (“WATCH ON DEMAND”):** #0099CC fill, #FFFFFF text, 18px/500, 5px radius, padding 12px 48px.
- **button-secondary (“DOWNLOAD NOW”):** #ACDE1F fill, #000000 text, 18px/500, 5px radius, padding 12px 48px.
- **button-tertiary (“LEARN NOW”):** #12E2E2 fill, #000000 text, 18px/500, 5px radius, padding 12px 48px.
- **input-field (“Name”):** #FFFFFF fill, #555555 text, 16px/400, 5px radius, padding 15px.
- **link:** transparent fill, #FFFFFF text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page.
- Do keep text in 4 levels: #000000, #202020, #555555, #777777.
- Do use #003366 as the brand accent: header, logo and key highlights.
- Do set headlines in Open Sans with tight tracking (-0.01em).
- Do reuse the measured spacing steps (5px, 15px, 32px).
- Do use 5px corners on most elements; larger surfaces also use 2px and 30px.
- Don't use #777777 for body text; it reaches 4.48:1 on #FFFFFF. Keep it for large text or metadata.
- Don't add drop shadows for depth; use borders and contrast.
- Don't introduce new font families beyond Open Sans.
- Don't use #003366 for large backgrounds or body text.
- Don't make interface transitions slower than 0.45s.

## Motion

Interface transitions are quick: 0.3s, 0.2s, 0.1s, 0.45s.

- **Easing:** `ease`, `linear`, `cubic-bezier(0.25, 1, 0.33, 1)`.
