## Description
|
|
<section id='description'>
|
|
After you create your variable, you can assign its value to other CSS properties by referencing the name you gave it.
|
|
<blockquote>background: var(--penguin-skin);</blockquote>
|
|
This will change the background of whatever element you are targeting to gray because that is the value of the <code>--penguin-skin</code> variable.
|
|
Note that styles will not be applied unless the variable names are an exact match.
|
|
</section>
|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
Apply the <code>--penguin-skin</code> variable to the <code>background</code> property of the <code>penguin-top</code>, <code>penguin-bottom</code>, <code>right-hand</code> and <code>left-hand</code> classes.
|
|
