Which statement is true about CSS's role in web design?

• A. CSS is not used for layout
• B. CSS has no impact on accessibility
• C. CSS provides a consistent look and feel but doesn't simplify change management
• D. CSS provides a consistent look and feel to site pages, and simplifies change management issues

Answer: (D)

CSS controls how content looks and how it's laid out, so it applies to layout, typography, colors, and spacing across a whole site. Because styling is centralized in one or more stylesheets, you can enforce a uniform appearance on every page. When you want to change the look, you modify the stylesheet, and those changes propagate to all pages that use it, making updates faster and less error-prone. That combination—a consistent look plus easier maintenance—is what makes CSS’s role essential in web design.

The other statements miss important realities. CSS is indeed used for layout, thanks to features like flexbox and grid. CSS also impacts accessibility—careful choices around color contrast, focus styles, and responsive typography can improve or harm how accessible a site is. Saying CSS doesn’t simplify change management ignores the major maintenance benefit of centralizing styling in one place.
