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。

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%

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%

const top = (s) => new __helpers.CSSHelp(document).getStyle(s)?.top
assert.equal(top('.cabin:nth-of-type(1)') || top('.cabin:first-of-type'),'50%');
