That's why I went with single line too. I found it easier to scan selectors and then once I've zeroed in on the group I want I could scan across for the properties.

I can understand the issues though. Anyone who works with version control and needs to compare files would prefer multiple lines. it's interesting hearing everyone's opinions.

I think some of this comes down to whether you work alone or in a team and what your overall development process is. What works under one set of conditions may not work so well under another.
