## Description
|
|
<section id='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 <code>let</code> and <code>const</code> keywords. In Sass, variables start with a <code>$</code> followed by the variable name.
|
|
Here are a couple examples:
|
|
<blockquote>$main-fonts: Arial, sans-serif;<br>$headings-color: green;<br><br>//To use variables:<br>h1 {<br> font-family: $main-fonts;<br> color: $headings-color;<br>}</blockquote>
|
|
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
|
|
<section id='instructions'>
|
|
Create a variable <code>$text-color</code> and set it to red. Then change the value of the <code>color</code> property for the <code>.blog-post</code> and <code>h2</code> to the <code>$text-color</code> variable.

tests:
|
|
- text: Your code should have a Sass variable declared for <code>$text-color</code> with a value of red.
|
|
testString: assert(code.match(/\$text-color:\s*?red;/g), 'Your code should have a Sass variable declared for <code>$text-color</code> with a value of red.');
|
|
- text: Your code should use the <code>$text-color</code> variable to change the <code>color</code> for the <code>.blog-post</code> and <code>h2</code> items.
|
|
testString: assert(code.match(/color:\s*?\$text-color;/g), 'Your code should use the <code>$text-color</code> variable to change the <code>color</code> for the <code>.blog-post</code> and <code>h2</code> items.');
|
|
- text: Your <code>.blog-post</code> element should have a </code>color</code> of red.
|
|
testString: assert($('.blog-post').css('color') == 'rgb(255, 0, 0)', 'Your <code>.blog-post</code> element should have a </code>color</code> of red.');
|
|
- text: Your <code>h2</code> elements should have a </code>color</code> of red.
|
|
testString: assert($('h2').css('color') == 'rgb(255, 0, 0)', 'Your <code>h2</code> elements should have a </code>color</code> of red.');
