I don't know what I'm doing wrong. Code challenges should have answer sheets.

"..answer sheets" .. that's really funny! Thanks for the chuckle! :smile:

But seriously, one of the aspects of the code challenges I've found really useful is that when I can't immediately pass it, it causes me to look up some documentation or review a video. I found that helps the knowledge "sink in" way more than would a simple "oh, you missed it - here's the answer".

I have to agree with Steven... "Answer sheets" kind of defeat the purpose of the Code Challenges. I may be wrong, but I don't believe you are given "Answer sheets" in Real Life situations.

That's why the Community is here. That's why developers make great use of Google.

I do understand needing a little help now and then, and I think hints can also help learning so here's a few:

  • the placeholder name is super_link (with an underscore)
  • you'll need to use the @extend keyword (as you already did with dogs)
  • remember you can nest rules in sass
  • what you did with dogs might make a good template for a nested rule

I'll bet you can get it now without an explicit spoiler.

Sure, I get your point. I could raise a question everytime I'm stuck in some challenge, but I don't want to clutter up the forum and do that. As you mention, hints, rather than : Bummer! There's something wrong with your Sass stylesheet. Please review your code and try again. Sass Error: Invalid CSS after " a %super_link": expected "{", was ";}" would provide a much better learning experience.

Thanks for your help and your time Steve
