CSS Outline Width

🎯 한 줄 통찰 (One-line insight)

The outline-width property specifies the width of an outline, set either as a keyword (thin, medium, thick) or as a specific size. [S1]

🧠 핵심 개념 (Core concepts)

• Purpose — the outline-width property specifies the width (thickness) of an outline. [S1]
• Keyword values — thin (typically 1px), medium (typically 3px), and thick (typically 5px). [S1]
• Explicit size — a specific size in px, pt, cm, em, etc. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Keyword vs. explicit — use thin/medium/thick for quick relative sizing, or a length unit when an exact thickness is required. [S1]
• Requires a style — outline-width is only visible alongside a set outline-style (e.g., solid). [S1]

📖 세부 내용 (Details)

Accepted values The outline-width property specifies the outline's dimensions with these accepted values: [S1]
