Challenge: Improve Compatibility with Browser Fallbacks

Link to the challenge:


You removed the background: var(--red-color); from the original code. Instead of modifying this, you are supposed to put your fallback value in that empty line above it. :slight_smile:

where to insert please tell

put it back where it was originally, you have to add a thing in this code, without removing anything
