CSS Grid Container

🎯 한 줄 통찰 (One-line insight)

A grid container contains one or more grid items arranged in columns and rows; an element becomes a grid container by setting display to grid or inline-grid, and all its direct children automatically become grid items. [S1]

🧠 핵심 개념 (Core concepts)

• Grid container definition — a grid container contains one or more grid items arranged in columns and rows. [S1]
• Automatic grid items — all direct child elements of a grid container automatically become grid items. [S1]
• Two display modes — set display: grid (block-level) or display: inline-grid (inline) to make the container. [S1]
• Container-level properties — alignment and sizing are controlled by container properties such as justify-content, align-content, align-items, grid-template-columns, grid-template-rows, column-gap, row-gap, gap, and place-content. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Declare the container first — set display: grid (or inline-grid) before any grid-template or alignment property takes effect. [S1]
• Alignment lives on the container — justify-content aligns items horizontally; align-content aligns them vertically inside the container. [S1]

📖 세부 내용 (Details)

A grid container contains one or more grid items arranged in columns and rows. All direct child elements of a grid container automatically become grid items. An element becomes a grid container by setting the display property to grid or inline-grid. [S1]
