[S1] ## 🧠 핡심 κ°œλ… (Core concepts) - **Grid Layout Module** β€” offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use float or positioning. [S1] - **Two-dimensional** β€” CSS Grid is used for two-dimensional layout, with rows AND columns; CSS Flexbox is used for one-dimensional layout, with rows OR columns. [S1] - **Grid Container** β€” the parent element where `display` is set to `grid` or `inline-grid`. [S1] - **Grid Items** β€” the direct children of the grid container, which automatically become grid items. [S1] ## 🧩 μΆ”μΆœλœ νŒ¨ν„΄ (Extracted patterns) - **Container + items model** β€” set `display: grid` on the parent; direct children automatically become grid items. [S1] - **Define columns on the container** β€” `grid-template-columns` controls how many columns and their widths (e.g., `auto auto auto` for three equal columns). [S1] ## πŸ“– μ„ΈλΆ€ λ‚΄μš© (Details) The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use float or positioning. [S1] **Grid vs Flexbox** CSS Grid is used for two-dimensional layout, with rows AND columns. CSS Flexbox is used for one-dimensional layout, with rows OR columns. [S1] **Grid Components** A grid consists of two essential parts: [S1] 1. **Grid Container** β€” the parent element where `display` is set to `grid` or `inline-grid`. 2. **Grid Items** β€” direct children of the grid container that automatically become grid items. **Complete example** [S1] ```html

``` The page also lists a CSS Grid properties table covering grid-related properties such as `grid-template-columns`, `grid-template-rows`, `gap`, `grid-area`, `justify-content`, and `align-items`, each with a brief description of its functionality. The full property-by-property table text was not captured verbatim from the source. ## πŸ› οΈ 적용 사둀 (Applied in summary) The page's own complete example styles a `.container` with `display: grid` and `grid-template-columns: auto auto auto`, plus styled child `
` items. No external project/commit applications found in the source. ## πŸ’» μ½”λ“œ νŒ¨ν„΄ (Code patterns) Make a three-column grid container (language: CSS): ```css .container { display: grid; grid-template-columns: auto auto auto; } ``` ## βš–οΈ 비ꡐ 및 선택 κΈ°μ€€ (Comparison & decision criteria) - **CSS Grid** β€” two-dimensional layout, controlling rows AND columns together.
