--description--
让我们再试一次,不过这一次轮到 margin
了。
同样,每个方向的外边距值可以在 margin
属性里面汇总声明,而无需分别通过 margin-top
、margin-right
、margin-bottom
、margin-left
分别声明,代码如下:
margin: 10px 20px 10px 20px;
这四个值按顺时针排序:上、右、下、左。汇总声明的效果与为每一个方向单独声明 margin
的效果是一致的。
--instructions--
按照顺时针顺序,将 class 为 "blue-box" 元素的上外边距以及左外边距设置为 40px
,右外边距和下外边距设置为 20px
。
--hints--
class 为 blue-box
的元素的上外边距应为 40px
。
assert($('.blue-box').css('margin-top') === '40px');
class 为 blue-box
的元素的右外边距应为 20px
。
assert($('.blue-box').css('margin-right') === '20px');
class 为 blue-box
的元素的下外边距应为 20px
。
assert($('.blue-box').css('margin-bottom') === '20px');
class 为 blue-box
的元素的左外边距应为 40px
。
assert($('.blue-box').css('margin-left') === '40px');
应沿顺时针方向设置 blue-box
的外边距。
const removeCssComments = (str) => str.replace(/\/\*[\s\S]+?\*\//g, '');
assert(
/\.blue-box\s*{[\s\S]*margin[\s]*:\s*\d+px\s+\d+px\s+\d+px\s+\d+px(;\s*[^}]+\s*}|;?\s*})/.test(
removeCssComments($('style').text())
)
);
