Which design phrase tells us to strive for simplicity all through the site?

• A. Keep It Simple, Stupid (KISS)
• B. Less is more
• C. Minimal viable product
• D. Design for scale

Answer: (A)

In UI design, keeping things simple across an entire site is crucial for usability. Keep It Simple, Stupid (KISS) is the phrase that signals this discipline—the idea is to minimize unnecessary complexity in layouts, interactions, and features so users can find what they need without cognitive overload. By favoring straightforward navigation, clear labeling, and a minimal path to task completion, the site becomes easier to learn and faster to use. While the other ideas touch related themes—Less is more points to minimalism, Minimal viable product focuses on launching with a small feature set, and Design for scale deals with growth—none sum up the universal aim of simplicity across the whole site the way KISS does.
