CSS Flex Items

🎯 한 줄 통찰 (One-line insight)

The direct child elements of a flex container automatically become flex items, controllable through six properties: order, flex-grow, flex-shrink, flex-basis, flex, and align-self. [S1]

🧠 핵심 개념 (Core concepts)

• Automatic flex items — the direct child elements of a flex container automatically become flex items. [S1]
• Six item-level properties — order, flex-grow, flex-shrink, flex-basis, flex (shorthand), and align-self. [S1]
• align-self overrides the container — it overrides the default alignment set by the container's align-items property. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Item properties go on the child, not the container — these properties are set on individual flex items (often inline in the examples). [S1]
• flex as a shorthand — combine flex-grow, flex-shrink, and flex-basis into a single flex declaration. [S1]

📖 세부 내용 (Details)

The direct child elements of a flex container automatically becomes flex items. Flex items can be controlled through six key properties. [S1]

1. The order Property The order property specifies the display order of the flex items inside the flex container. The default value is 0, and the value must be a number. [S1]

<div class="flex-container">
  <div style="order: 3">1</div>
  <div style="order: 2">2</div>
  <div style="order: 4">3</div>
  <div style="order: 1">4</div>
</div>

2. The flex-grow Property The flex-grow property specifies how much a flex item will grow relative to the rest of the flex items. The default value is 0. [S1]

<div class="flex-container">
  <div style="flex-grow: 1">1</div>
  <div style="flex-grow: 1">2</div>
  <div style="flex-grow: 4">3</div>
</div>

3. The flex-shrink Property The flex-shrink property specifies how much a flex item will shrink relative to the rest of the flex items. The default value is 1. [S1]

<div class="flex-container">
  <div>1</div>
  <div>2</div>
  <div style="flex-shrink: 2">3</div>
  <div>4</div>
  <div>5</div>
  <div>6</div>
</div>

4. The flex-basis Property The flex-basis property specifies the initial length of a flex item. [S1]

<div class="flex-container">
  <div>1</div>
  <div>2</div>
  <div style="flex-basis: 250px">3</div>
  <div>4</div>
</div>

5. The flex Property The flex property is a shorthand property for the flex-grow, flex-shrink, and flex-basis properties. [S1]

<div class="flex-container">
  <div>1</div>
  <div>2</div>
  <div style="flex: 1 0 150px">3</div>
  <div>4</div>
</div>

6. The align-self Property The align-self property specifies the alignment for the selected item inside the flexible container. This property overrides the default alignment set by the container's align-items property. [S1]

<div class="flex-container">
  <div>1</div>
  <div>2</div>
  <div style="align-self: center">3</div>
  <div>4</div>
</div>

<div class="flex-container">
  <div>1</div>
  <div style="align-self: flex-start">2</div>
  <div style="align-self: flex-end">3</div>
  <div>4</div>
</div>

🛠️ 적용 사례 (Applied in summary)
