# --description--
|
||
|
|
|
||
|
|
在 `one` 元素下方添加另一個 `div`，其 `class` 值爲 `two`。 這將是你的第二個矩形。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
不應更改現有的 `.one` 元素。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelectorAll('.one').length === 1);
|
||
|
|
```
|
||
|
|
|
||
|
|
`.canvas` 元素中應該有第二個 `div` 元素。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelector('.canvas').children[1].tagName === 'DIV');
|
||
|
|
```
|
||
|
|
|
||
|
|
第二個 `div` 元素的 `class` 值應爲 `two`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelector('.canvas').children[1].className.split(' ').includes('two'));
|
||
|
|
```
|
||
|
|
|
||
|
|
`.two` 元素應該在 `.one` 元素之後。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelector('.two').previousElementSibling.className.split(' ').includes('one'));
|
||
|
|
```
