Which concept uses grey placeholder shapes shown before content loads (for example, YouTube's blank boxes before video plays)?

• A. Ridge Racer Easter egg
• B. Skeleton screen
• C. Splash Screen
• D. Console output

Answer: (B)

Skeleton screens use grey placeholder shapes that resemble the final layout of the content, shown while actual content is loading. This approach gives users a sense of the page structure and where things will appear, which makes the wait feel shorter because the space for images, text blocks, and controls is already visible. In practice like YouTube’s load phase, you’ll see gray boxes or bars where the video player, thumbnails, or comments will appear, and these placeholders are replaced by real content as soon as it finishes loading. This is different from a splash screen, which is shown only at app startup to mask initialization, and from console output, which is just text logs and not a visual loading placeholder within the page.
