Challenge: Learn CSS Variables by Building a City Skyline - Step 14

Link to the challenge:

Where are you getting the directions to add root? The directions say

begin with two dashes (- ) and are given a name and a value like this: --variable-name: value; . In the rule for the bb1 class, create a variable named --building-color1 and give it a value of #999 .

maybe in a future challenge root will be introduced, but not here

You need to simply add --variable-name: value; in the given code that much simple it is !!
