# [[CSS Grid Item Named]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
Naming grid items with `grid-area` and arranging those names inside `grid-template-areas` (each row in apostrophes, names separated by spaces, a period for unnamed cells) lets you describe a whole page layout as a readable visual map. [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **`grid-template-areas`** — a grid container property that specifies areas within the grid layout. [S1]
|
||||
- **`grid-area` naming** — you name grid items with the `grid-area` property, then reference the name in `grid-template-areas`. [S1]
|
||||
- **Apostrophe rows** — each area (row) is defined within apostrophes; the named grid items in each area are listed inside the apostrophes, separated by a space. [S1]
|
||||
- **Period for unnamed cells** — a period sign (`.`) refers to a grid item with no name. [S1]
|
||||
- **Multiple rows** — to define two rows (two areas), define the second row inside another set of apostrophes. [S1]
|
||||
|
||||
## 🧩 추출된 패턴 (Extracted patterns)
|
||||
- **Span by repetition** — repeating a name across several cells in a row makes that item span those columns (e.g. five times = span five columns). [S1]
|
||||
- **Vertical span** — repeating a name across two apostrophe-rows makes the item span two rows. [S1]
|
||||
- **Full-page template** — naming every item (header, menu, main, right, footer) and laying them out in `grid-template-areas` produces a ready-to-use webpage template. [S1]
|
||||
|
||||
## 📖 세부 내용 (Details)
|
||||
**Naming Grid Items with grid-area**
|
||||
The CSS `grid-template-areas` is a grid container property, and it specifies areas within the grid layout. You can name grid items by using the CSS `grid-area` property, and then reference the name in the `grid-template-areas` property. Each area is defined within apostrophes. The named grid items in each area are defined inside the apostrophes, separated by a space. [S1]
|
||||
|
||||
Let 'Item1' get the name 'myHeader', and let it span five columns in a five-columns grid layout: [S1]
|
||||
```css
|
||||
.container {
|
||||
display: grid;
|
||||
grid-template-areas: 'myHeader myHeader myHeader myHeader myHeader';
|
||||
}
|
||||
|
||||
.item1 {
|
||||
grid-area: myHeader;
|
||||
}
|
||||
```
|
||||
|
||||
We can use a period sign (`.`) to refer to a grid item with no name. Let 'myHeader' span three columns in a five-columns grid layout (a period sign represents an item with no name): [S1]
|
||||
```css
|
||||
.container {
|
||||
display: grid;
|
||||
grid-template-areas: 'myHeader myHeader myHeader . .';
|
||||
}
|
||||
|
||||
.item1 {
|
||||
grid-area: myHeader;
|
||||
}
|
||||
```
|
||||
|
||||
To define two rows (two areas), define the second row inside another set of apostrophes. Let 'myHeader' span two columns and two rows: [S1]
|
||||
```css
|
||||
.container {
|
||||
display: grid;
|
||||
grid-template-areas:
|
||||
'myHeader myHeader . . .'
|
||||
'myHeader myHeader . . .';
|
||||
}
|
||||
|
||||
.item1 {
|
||||
grid-area: myHeader;
|
||||
}
|
||||
```
|
||||
|
||||
**Make a ready-to-use Webpage Template**
|
||||
Here, we name all grid items to make a ready-to-use webpage template: [S1]
|
||||
```css
|
||||
.item1 { grid-area: header; }
|
||||
.item2 { grid-area: menu; }
|
||||
.item3 { grid-area: main; }
|
||||
.item4 { grid-area: right; }
|
||||
.item5 { grid-area: footer; }
|
||||
|
||||
.container {
|
||||
display: grid;
|
||||
grid-template-areas:
|
||||
'header header header header header header'
|
||||
'menu main main main main right'
|
||||
'menu footer footer footer footer footer';
|
||||
}
|
||||
```
|
||||
The resulting layout shows the labeled areas Header, Menu, Main, Right, and Footer. [S1]
|
||||
|
||||
## 🛠️ 적용 사례 (Applied in summary)
|
||||
The page's culminating applied case is the ready-to-use webpage template that names header, menu, main, right, and footer items and maps them across a six-column, three-row `grid-template-areas`. No external project/commit applications found in the source.

||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
Name an item and reference it (language: CSS):
|
||||
```css
|
||||
.container {
|
||||
display: grid;
|
||||
grid-template-areas: 'myHeader myHeader myHeader . .';
|
||||
}
|
||||
|
||||
.item1 {
|
||||
grid-area: myHeader;
|
||||
}
|
||||
```
|
||||
Full webpage template layout:
|
||||
```css
|
||||
.item1 { grid-area: header; }
|
||||
.item2 { grid-area: menu; }
|
||||
.item3 { grid-area: main; }
|
||||
.item4 { grid-area: right; }
|
||||
.item5 { grid-area: footer; }
|
||||
|
||||
.container {
|
||||
display: grid;
|
||||
grid-template-areas:
|
||||
'header header header header header header'
|
||||
'menu main main main main right'
|
||||
'menu footer footer footer footer footer';
|
||||
}
|
||||
```
