CSS Flexbox Justify Content

🎯 한 줄 통찰 (One-line insight)

The justify-content property aligns flex items along the main-axis (horizontally) within a flex container, offering values from simple edge/center alignment to several space-distribution modes. [S1]

🧠 핵심 개념 (Core concepts)

• Main-axis alignment — justify-content controls how flex items are positioned along the main-axis (horizontally) inside a flex container. [S1]
• Default is flex-start — items align at the beginning of the container unless another value is set. [S1]
• Two families of values — positional (center, flex-start, flex-end) and space-distribution (space-around, space-between, space-evenly). [S1]

🧩 추출된 패턴 (Extracted patterns)

• Apply on the container — justify-content is always declared on the element with display: flex, not on the items. [S1]
• Space distribution choice — pick space-between (no outer space), space-around (half-size outer space), or space-evenly (equal space everywhere) depending on the desired edge gaps. [S1]

📖 세부 내용 (Details)

The justify-content property aligns the flex items along the main-axis (horizontally) within a flex container. [S1]

center — aligns the flex items in the center of the container. [S1]

.flex-container {
  display: flex;
  justify-content: center;
}

flex-start — aligns the flex items at the beginning of the container (this is default). [S1]

.flex-container {
  display: flex;
  justify-content: flex-start;
}

flex-end — aligns the flex items at the end of the container. [S1]

.flex-container {
  display: flex;
  justify-content: flex-end;
}

space-around — displays the flex items with space before, between, and after the lines. [S1]

.flex-container {
  display: flex;
  justify-content: space-around;
}

space-between — displays the flex items with space between the lines. [S1]

.flex-container {
  display: flex;
  justify-content: space-between;
}

space-evenly — displays the flex items with equal space around them. [S1]

.flex-container {
  display: flex;
  justify-content: space-evenly;
}

🛠️ 적용 사례 (Applied in summary)

The page's own examples apply each value to a .flex-container declared with display: flex. No external project/commit applications found in the source.

💻 코드 패턴 (Code patterns)

Align flex items on the main-axis (language: CSS):

.flex-container {
  display: flex;
  justify-content: center; /* or flex-start | flex-end | space-around | space-between | space-evenly */
}

⚖️ 비교 및 선택 기준 (Comparison & decision criteria)

• space-between — no space before the first or after the last item; full gaps only between items. [S1]
• space-around — space before, between, and after the lines (outer gaps are half the inner gaps). [S1]
• space-evenly — equal space around every item, including the container edges. [S1]
