## 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.

|

|
- 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.
