CSS Syntax

🎯 한 줄 통찰 (One-line insight)

A CSS rule is made of a selector that points to the HTML element to style and a declaration block containing one or more property: value; declarations, separated by semicolons and surrounded by curly braces. [S1]

🧠 핵심 개념 (Core concepts)

• A CSS rule has two parts — a selector and a declaration block. [S1]
• Selector — points to the HTML element you want to style. [S1]
• Declaration block — contains one or more declarations separated by semicolons. [S1]
• Declaration — includes a CSS property name and a value, separated by a colon. [S1]
• Punctuation — multiple CSS declarations are separated with semicolons, and declaration blocks are surrounded by curly braces. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Rule pattern — selector { property: value; property: value; }. [S1]
• Declaration pattern — each declaration pairs a property and a value with a colon: property: value;. [S1]

📖 세부 내용 (Details)

A CSS rule consists of a selector and a declaration block. [S1]

The selector points to the HTML element you want to style. The declaration block contains one or more declarations separated by semicolons. Each declaration includes a CSS property name and a value, separated by a colon. Multiple CSS declarations are separated with semicolons, and declaration blocks are surrounded by curly braces. [S1]

Example [S1]

p {
  color: red;
  text-align: center;
}

In this example: [S1]

• p is the selector (it targets HTML <p> paragraph elements).
• color is a property, and red is its value.
• text-align is a property, and center is its value.

The rule above makes all paragraph text red and center-aligned. [S1]
