# --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:
|
|
|
|
```scss
|
|
$main-fonts: Arial, sans-serif;
|
|
$headings-color: green;
|
|
```
|
|
|
|
並使用變量:
|
|
|
|
```scss
|
|
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。
|
|
|
|
```js
|
|
assert(code.match(/\$text-color\s*:\s*?red\s*;/g));
|
|
```
|
|
|
|
應使用 `$text-color` 變量來更改 `.blog-post` 和 `h2` 的 `color`。
|
|
|
|
```js
|
|
assert(code.match(/color\s*:\s*\$text-color\s*;?/g));
|
|
```
|
|
|
|
`.blog-post` 元素 `color` 應爲紅色。
|
|
|
|
```js
|
|
assert($('.blog-post').css('color') == 'rgb(255, 0, 0)');
|
|
```
|
|
|
|
`h2` 元素的 `color` 應爲紅色。
|
|
|
|
```js
|
|
assert($('h2').css('color') == 'rgb(255, 0, 0)');
|
|
```
