What is a core component of a design system?
UI component library
User acceptance testing protocol
Bug tracking system
Scrum board
A design system's core component is the UI component library, which provides reusable building blocks for consistent user interfaces. Bug tracking, Scrum boards, and testing protocols are part of project management or QA processes, not design system components.
Which of the following best describes design tokens?
Shared design values like colors, spacing, and typography
A method for versioning design assets
A documentation format for user research
Code snippets for implementing ARIA roles
Design tokens are named entities that store visual design attributes, such as color, spacing, and typography, to ensure consistent styling across platforms. They are not code snippets for ARIA, documentation formats, or versioning methods.
What is the primary purpose of a pattern library in a design system?
To plan project timelines
To store reusable UI patterns and components
To track user testing feedback
To manage code versioning histories
A pattern library organizes and displays reusable UI patterns and components for designers and developers. Version control, testing feedback, and project planning are separate processes outside the scope of a pattern library.
Which file type is commonly used to define color design tokens?
README.md
index.html
main.scss
design-tokens.json
Design tokens, including color values, are often defined in a JSON file like design-tokens.json to allow easy export to various platforms. HTML, Markdown, and SCSS files are not standardized formats for token definition.
In the context of design systems, what does scalability refer to?
Speed of CSS animations
Consistent growth and reuse of components across multiple projects
Number of designers working on the project
The resolution of images used in UI
Scalability in design systems means creating reusable components and patterns that can grow and be applied across many projects. Image resolution, animation speed, and team size are not definitions of system scalability.
In Atomic Design methodology, which element follows molecules in the hierarchy?
Organisms
Pages
Atoms
Templates
In Atomic Design, atoms combine to form molecules, and molecules combine to form organisms. Templates and pages come later in the hierarchy, and atoms are the smallest units.
Which best practice enhances accessibility for interactive components?
Providing clear keyboard focus styles
Using only
elements for controls
Using low-contrast text to reduce glare
Disabling hover states for all elements
Clear keyboard focus styles help users who navigate via keyboard to see which element is active, improving accessibility. Low-contrast text and misuse of elements hinder accessibility, and disabling hover states unnecessarily can remove helpful cues.
What advantage does semantic HTML provide in a component library?
Improved accessibility and SEO
Automatic color theming
Faster CSS rendering
Smaller image file sizes
Semantic HTML tags like
Which naming convention is generally recommended for design tokens?
Random alphanumeric strings
camelCase for consistency and readability
Emojis to represent colors
Spaces in property names for clarity
Using camelCase for token names ensures consistency and readability in code. Spaces, emojis, or random strings would create parsing issues and reduce clarity.
How should design tokens be structured to improve organization?
All tokens in a single flat array
Separate tokens into multiple CSS files
Hierarchically grouped in JSON by category and type
List tokens in a plain text document
Organizing tokens hierarchically in JSON by categories like color, typography, and spacing helps maintain clarity and scalability. Flat arrays, multiple unrelated CSS files, or plain text documents reduce structure and maintainability.
Which ARIA role is appropriate for a custom button component?
alert
list
button
navigation
Custom interactive elements that behave like buttons should use the ARIA role 'button' to ensure screen readers treat them correctly. Navigation, alert, and list roles convey different meanings.
Which tool is widely used for documenting and previewing UI components?
Storybook
Terminal CLI
Adobe Photoshop
Microsoft Excel
Storybook is a popular tool for building, documenting, and testing UI components in isolation. Photoshop is for graphics, Excel is a spreadsheet, and the terminal is a command-line environment.
What is the main benefit of 'living documentation' in a pattern library?
It slows down the development process
It hides component usage examples
It always reflects the current code implementation
It increases the risk of code bugs
Living documentation is automatically updated alongside code changes, ensuring that documentation stays in sync with the implementation. It does not inherently slow development or increase bugs, and it typically shows usage examples.
How do design tokens facilitate theming in applications?
By switching token values at runtime based on theme
By caching HTML outputs
By compressing image files
By minifying CSS assets
Design tokens allow themes to swap sets of values (like color or spacing) at runtime, enabling dynamic theming. Minification, image compression, and caching HTML are unrelated to token-based theming.
What does modularity mean in a scalable design workflow?
Using a single global stylesheet
Writing inline styles for every element
Combining all styles into one file
Building reusable, independent components
Modularity in design workflows refers to creating independent, reusable components that can be assembled in different contexts. Inline styles or monolithic files reduce flexibility and maintainability.
Which theming strategy uses token aliases to switch between light and dark modes?
Embedding images for each theme
Mapping semantic tokens to mode-specific token values
Hard-coding colors directly in components
Using separate CSS files without tokens
Alias theming involves defining semantic tokens that reference different mode-specific values for light or dark themes. Hard-coding colors, separate CSS, or image embedding are less flexible and not token-based strategies.
How can a design system team ensure cross-platform consistency?
Ignoring native platform guidelines
Using platform-agnostic design tokens and shared component specs
Developing entirely separate systems per platform
Manually synchronizing designs with screenshots
Platform-agnostic tokens and shared specs allow designers and developers to maintain consistent styles and behaviors across web, iOS, and Android. Separate systems or manual processes increase duplication and errors.
Which metric best assesses the scalability of a design system?
Average color contrast ratio
Total lines of CSS code
Number of reusable components across projects
Number of Git commits
A scalable design system is measured by how many components can be reused across projects, indicating its adaptability and reach. Color contrast is an accessibility metric, and code size or commits don't directly reflect system scalability.
According to WCAG, what is the minimum color contrast ratio for normal text to be accessible?
3:1
4.5:1
7:1
2:1
WCAG requires a minimum contrast ratio of 4.5:1 for normal text to ensure readability for users with visual impairments. Ratios like 3:1 and 2:1 are too low, while 7:1 is the enhanced level for AAA compliance.
Which versioning approach supports backward compatibility in design systems?
No versioning, always using 'latest'
Date-only version identifiers (e.g., 20230701)
Randomly incrementing numbers for each update
Semantic versioning with clear major, minor, and patch releases
Semantic versioning (e.g., v2.1.0) clearly indicates backward-incompatible changes (major) and compatible additions (minor, patch), helping teams maintain compatibility. Random or date-only schemes lack clarity on compatibility.
