# --description--
|
||
|
|
|
||
|
|
爲了使冰山更有層次，添加另一座冰山，在 `.left-mountain` 後面創建一個新的 `div`，設置這個 `div` 的 `class` 爲 `back-mountain`。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
應該在 `body` 內添加一個新的 `div`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.equal(document.querySelectorAll('body > div')?.length, 4);
|
||
|
|
```
|
||
|
|
|
||
|
|
`div` 的 `class` 應該爲 `back-mountain`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.include(document.querySelector('div:not(.left-mountain, .ground, .penguin)')?.className, 'back-mountain');
|
||
|
|
```
|
||
|
|
|
||
|
|
`.back-mountain` 應該在 `.left-mountain` 後面。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.strictEqual(document.querySelector('.left-mountain')?.nextElementSibling, document.querySelector('.back-mountain'));
|
||
|
|
```
|
||
|
