# --description--
是時候將機艙定位在車輪周圍了。 選擇第一個 `.cabin` 元素。 將 `right` 屬性設置爲 `-8.5%`，將 `top` 屬性設置爲 `50%`。
# --hints--
你應該有一個 `.cabin:nth-of-type(1)` 選擇器。
```js
const def = (s) => new __helpers.CSSHelp(document).getStyle(s)
assert.exists(def('.cabin:first-of-type') || def('.cabin:nth-of-type(1)'));
```
你的 `.cabin:nth-of-type(1)` 選擇器應該有一個 `right` 屬性值爲 `-8.5%`。
```js
const right = (s) => new __helpers.CSSHelp(document).getStyle(s)?.right
assert.equal(right('.cabin:nth-of-type(1)') || right('.cabin:first-of-type'), '-8.5%');
```
你的 `.cabin:nth-of-type(1)` 選擇器應該有一個 `top` 屬性值爲 `50%`。
```js
const top = (s) => new __helpers.CSSHelp(document).getStyle(s)?.top
assert.equal(top('.cabin:nth-of-type(1)') || top('.cabin:first-of-type'),'50%');
```
