--description--
Sass 不同於 CSS 的一個特點是它允許使用變量。 可以在 Sass 中聲明變量,併爲它賦值,就像在 JavaScript 中一樣。
在 JavaScript 中,變量是使用 let
和 const
關鍵字定義的。 在 Sass 中,變量以 $
開頭的,後跟變量名。
這裏有幾個例子:
$main-fonts: Arial, sans-serif;
$headings-color: green;
並使用變量:
h1 {
font-family: $main-fonts;
color: $headings-color;
}
當需要把多個元素設置成相同顏色時,變量就會很有用。 一旦需要更改顏色,只需要改變這個變量的值就好。
--instructions--
創建一個變量 $text-color
並將其設置爲 red
。 然後更改 .blog-post
和 h2
的 color
屬性的值爲 $text-color
變量。
--hints--
應該把 $text-color
聲明一個值爲 red
的 Sass 變量。
assert(code.match(/\$text-color\s*:\s*?red\s*;/g));
應使用 $text-color
變量來更改 .blog-post
和 h2
的 color
。
assert(code.match(/color\s*:\s*\$text-color\s*;?/g));
.blog-post
元素 color
應爲紅色。
assert($('.blog-post').css('color') == 'rgb(255, 0, 0)');
h2
元素的 color
應爲紅色。
assert($('h2').css('color') == 'rgb(255, 0, 0)');
