# --description--
|
|
|
|
One feature of Sass that's different than CSS is it uses variables. They are declared and set to store data, similar to JavaScript.
|
|
|
|
In JavaScript, variables are defined using the `let` and `const` keywords. In Sass, variables start with a `$` followed by the variable name.
|
|
|
|
Here are a couple examples:
|
|
|
|
```scss
|
|
$main-fonts: Arial, sans-serif;
|
|
$headings-color: green;
|
|
```
|
|
|
|
And to use the variables:
|
|
|
|
```scss
|
|
h1 {
|
|
font-family: $main-fonts;
|
|
color: $headings-color;
|
|
}
|
|
```
|
|
|
|
One example where variables are useful is when a number of elements need to be the same color. If that color is changed, the only place to edit the code is the variable value.
|
|
|
|
# --instructions--
|
|
|
|
Create a variable `$text-color` and set it to `red`. Then change the value of the `color` property for the `.blog-post` and `h2` to the `$text-color` variable.
|
|
|
|
# --hints--
|
|
|
|
Your code should have a Sass variable declared for `$text-color` with a value of `red`.
|
|
|
|
```js
|
|
assert(code.match(/\$text-color\s*:\s*?red\s*;/g));
|
|
```
|
|
|
|
Your code should use the `$text-color` variable to change the `color` for the `.blog-post` and `h2` items.
|
|
|
|
```js
|
|
assert(code.match(/color\s*:\s*\$text-color\s*;?/g));
|
|
```
|
|
|
|
Your `.blog-post` element should have a `color` of red.
|
|
|
|
```js
|
|
assert($('.blog-post').css('color') == 'rgb(255, 0, 0)');
|
|
```
|
|
|
|
Your `h2` elements should have a `color` of red.
|
|
|
|
```js
|
|
assert($('h2').css('color') == 'rgb(255, 0, 0)');
|
|
```
