Check what CSS controls in typography, wrapped decoration, top-layer presentation, and scrolling backgrounds. Each question has one answer and an explanation.
Review the decisions
- CSS unicode-range: request only the font subset a page uses
- CSS :lang(): style text from its declared language
- CSS ::backdrop: dim a modal without faking modality
- CSS background-attachment local: move decoration with scrolled content

Common Mistakes
- Do not treat presentation as stored data or platform behavior.
- Do not infer a network saving without inspecting real resource transfers.
