Which media query pattern applies styles for screens at least 768px wide?

• A. @media (min-width: 768px) { ... }
• B. @media (max-width: 768px) { ... }
• C. @media (orientation: portrait) { ... }
• D. @media (min-height: 600px) { ... }

Answer: (A)

The key idea is using a lower bound to trigger styles based on how wide the viewport is. A media query with min-width: 768px means the styles inside will apply when the screen is 768 pixels wide or wider. That’s exactly the behavior described: the styles activate for screens at least 768px wide, and the 768px value itself is included. In contrast, a pattern with max-width would run when the viewport is 768px or narrower, which targets smaller screens rather than larger ones. Patterns checking orientation or min-height test different conditions (device orientation or vertical space), not the horizontal width, so they don’t match the idea of “at least 768px wide.”
