bad87fee1348bd9aedf08826 使用順時針標記指定元素的內邊距 0 https://scrimba.com/c/cB7mBS9 18346 use-clockwise-notation-to-specify-the-padding-of-an-element

--description--

如果不想每次都要分別聲明 padding-toppadding-rightpadding-bottompadding-left 屬性,可以把它們彙總在一行裏面一併聲明,像是這樣:

padding: 10px 20px 10px 20px;

這四個值按順時針排序:上、右、下、左,並且設置的效果等同於分別聲明每一個方向的內邊距。

--instructions--

按照順時針順序,把 .blue-box class 的上內邊距以及左內邊距 padding 設置爲 40px,右內邊距和下內邊距則設置爲20px

--hints--

class 爲 blue-box 的元素的上內邊距 padding 應爲 40px

assert($('.blue-box').css('padding-top') === '40px');

class 爲 blue-box 的元素的右內邊距 padding 應爲 20px

assert($('.blue-box').css('padding-right') === '20px');

class 爲 blue-box 的元素的下內邊距 padding 應爲 20px

assert($('.blue-box').css('padding-bottom') === '20px');

class 爲 blue-box 的元素的左內邊距 padding 應爲 40px

assert($('.blue-box').css('padding-left') === '40px');

應該按照順時針排序,彙總聲明的方式來設置 blue-box 的內邊距。

assert(
  /\.blue-box\s*{[\s\S]*padding[\s]*:\s*\d+px\s+\d+px\s+\d+px\s+\d+px(;\s*[^}]+\s*}|;?\s*})/.test(
    __helpers.removeCssComments($('style').text())
  )
);
