Use CSS Variables to change several elements at once

CSS Variables are a powerful way to change many CSS style properties at once by changing only one value.

Follow the instructions below to see how changing just three values can change the styling of many elements.

 

 

TEST

In the penguin class, change the black value to gray, the gray value to white, and the yellow value to orange.

 

<style>
