# --description--
|
|||
|
|
|
|||
|
|
將元素轉換爲網格只會影響其子元素（即直接後代元素，英文爲 direct descendants。意思是一個元素的所有後代元素中，父級元素爲該元素的所有元素）。 因此，如果我們把某個子元素設置爲網格，就會得到一個嵌套的網格。
|
|||
|
|
|
|||
|
|
例如，如果我們設置 class 爲 `item3` 的元素的 `display` 和 `grid-template-columns` 屬性，就會得到一個嵌套的網格。
|
|||
|
|
|
|||
|
|
# --instructions--
|
|||
|
|
|
|||
|
|
請設置 `display` 和 `grid-template-columns`，使類爲 `item3` 元素轉換爲有兩列且寬度爲 `auto` 和 `1fr` 的網格。
|
|||
|
|
|
|||
|
|
# --hints--
|
|||
|
|
|
|||
|
|
class 爲 `item3` 的元素應具有 `grid-template-columns` 屬性且屬性值應爲 `auto` 和 `1fr`。
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
assert(
|
|||
|
|
code.match(
|
|||
|
|
/.item3\s*?{[\s\S]*grid-template-columns\s*?:\s*?auto\s*?1fr\s*?;[\s\S]*}/gi
|
|||
|
|
)
|
|||
|
|
);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
class 爲 `item3` 的元素應具有 `display` 屬性且屬性值應爲 `grid`。
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
assert(code.match(/.item3\s*?{[\s\S]*display\s*?:\s*?grid\s*?;[\s\S]*}/gi));
|
|||
|
|
```
