This is what was in the input field for me. The previous line for .background-buildings was not closed, so I have closed that. I added to the .bb1 class per the below and closed it. Now the error is stating i need to put them in order. I looked at the other solution for this and still cannot make sense of what im doing wrong. thanks.
