Explore the fundamentals of design system foundations with this quiz focused on colors, typography, and spacing. Assess your understanding of vital concepts for creating consistent, accessible, and visually balanced interfaces.
Which principle best ensures that text is readable against its background for users with visual impairments?
Explanation: Contrast ratio compliance is crucial for making text legible to people with visual impairments because it measures the luminance difference between foreground and background colors. Symmetrical alignment relates to layout balance and does not directly affect readability in terms of color. Variable line spacing changes the vertical distance between lines but does not help with color contrast. Font weight adjustment can improve readability, but if contrast is insufficient, bold text alone is not enough for accessibility.
When naming colors in a design system, which approach improves scalability and reduces confusion across a project?
Explanation: Semantic names such as 'Primary' or 'Error' communicate the intended purpose of a color, making it easier to manage changes and maintain consistency across a project. Naming by appearance like 'Light Blue' may become confusing if the actual color changes. Using hexadecimal codes as labels is not human-friendly and hinders collaboration. Referring to colors as 'Color 1' or 'Color 2' lacks any meaningful information about the color's function.
Which benefit comes from using a typographic scale, such as a modular scale, in a design system?
Explanation: A typographic scale provides predetermined font sizes based on ratios, resulting in a clear visual hierarchy and consistent rhythm in text styling. It does not impact the number of font files used in a project. While a scale simplifies responsive design, it does not eliminate the requirement for responsive layouts. The scale does not create random line breaks, as those are governed by layout and content, not the scale itself.
Which of the following is a recommended practice when defining spacing values in a design system?
Explanation: Standardized spacing tokens, such as 'space-md' or 'space-lg', help maintain consistency and simplify updates across a design system. Arbitrary pixel values lead to inconsistency and maintenance issues. Relying only on em units reduces flexibility and may not suit every context. Naming spacing after the component makes it harder to reuse the same spacing values across different elements, reducing scalability.
Which factor most directly impacts the readability of headings and body text in a digital interface?
Explanation: Line height, also known as leading, determines the vertical space between lines of text, greatly affecting how easily users can read blocks of text. Button hover color is related to interactive feedback, not text readability. Corner radius impacts the shape of elements, not textual clarity. Background blur is a visual effect that may affect text contrast but does not directly relate to the spacing within text lines.
