# --description--

和設置一個網格項佔用多列類似，你也可以設置它佔用多行。 你可以使用 `grid-row` 屬性來定義一個網格項開始和結束的水平線。

# --instructions--

請讓 class 爲 `item5` 的元素佔用最後兩行。

# --hints--

class 爲 `item5` 的元素應具有 `grid-row` 屬性。

```js
assert(
  __helpers.removeWhiteSpace($('style').text()).match(/\.item5{.*grid-row:.*}/g)
);
```

class 爲 `item5` 的元素應具有 `grid-row` 屬性，其屬性值應將元素設置爲佔用網格的最後兩行。

```js
const rowStart = getComputedStyle($('.item5')[0]).gridRowStart;
const rowEnd = getComputedStyle($('.item5')[0]).gridRowEnd;
const result = rowStart.toString() + rowEnd.toString();
const correctResults = [
  '24',
  '2-1',
  '2span 2',
  '2span2',
  'span 2-1',
  '-12',
  'span 2span 2',
  'span 2auto',
  'autospan 2'
];
assert(correctResults.includes(result));
```
