repeat 方法帶有一個名爲<dfn>自動填充(auto-fill)</dfn>的功能。 它的功能是根據容器的大小,儘可能多地放入指定大小的行或列。 你可以通過結合 `auto-fill` 和 `minmax` 來更靈活地佈局。
|
|
|
|
|
|
|
|
|
|
```css
|
|
|
|
|
repeat(auto-fill, minmax(60px, 1fr));
|
|
|
|
|
```

上面的代碼效果是這樣:首先,列的寬度會隨容器大小改變。其次,只要容器寬度不足以插入一個寬爲 60px 的列,當前行的所有列就都會一直拉伸。請自己調整寬度,動手試一下就不難理解了。 **注意:** 如果容器寬度不足以將所有網格項放在同一行,餘下的網格項將會移至新的一行。

在第一個網格中,請使用 `auto-fill` 和 `repeat` 來填充網格。 其中列寬的最小值爲 `60px`,最大值爲 `1fr`。 你可以調整最右側的預覽區大小,查看自動填充的效果。

class 爲 `container` 的元素應具有 `grid-template-columns` 屬性,且屬性值應使用 `repeat` 和 `auto-fill`,以便將最小寬度爲 `60px`、最大寬度爲 `1fr` 的列填充至網格。
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
assert(
|
|
|
|
|
code.match(
|
|
|
|
|
/.container\s*?{[\s\S]*grid-template-columns\s*?:\s*?repeat\s*?\(\s*?auto-fill\s*?,\s*?minmax\s*?\(\s*?60px\s*?,\s*?1fr\s*?\)\s*?\)\s*?;[\s\S]*}/gi
|
|
|
|
|
)
|
|
|
|
|
);
|
|
|
|
|
```
