Major organizations creating websites create a “Design System” publication which specifies the UX (User Experience) and provides tools for website designers to achieve a common UI (User Interface).

NOTE: Content here are my personal opinions, and not intended to represent any employer (past or present). “PROTIP:” here highlight information I haven’t seen elsewhere on the internet because it is hard-won, little-know but significant facts based on my personal research and experience.

UX includes more than colors, fonts (typography), icons (iconography), Design Tokens, line height, and other aspects of styling websites and Andriod/iOS mobile apps. Design Systems provide Guidelines on Voice and Tone, Animation, Accessibility, Layout, Navigation, Search, Messaging, Data Visualization, Localization, etc. Component blueprints provide examples to code components such as Accordion, Checkbox, etc. in the form of

React component library (JavaScript)
Custom font files

Common use of a UI coding (JavaScript, etc.) library makes scanning for security vulnerabilities (such as OWASP) more efficient, so the security of each app’s code is “built in” via the libraries used rather than individually tested out of custom code.

To create design systems, many use the Tailwind CSS compiler. It’s called an “atomic/utility-first” CSS framework (UI-kit). It’s best installed via npm. For better performance, Tailwind removes unused CSS using PurgeCSS, which can be incorporated into Jekyll and themes.

Design tokens

“think of a design token as a key that unlocks a specific value.”

Tokens are like nicknames for colors, opacity, shadows, etc. See VIDEO “What are Design Tokens”. Alias tokens are diverged Global Tokens made for context-specific purpose, to separate concerns.

Tokens are specified in SASS files, not token values.

A Measure of Line Height

USDS defines the “measure” token to standardize line heights:

1 = 44ex
2 = 60ex
3 = 64ex
4 = 68ex
5 = 72ex
6 = 88ex
‘none’ = no max width
