I appreciate the post addresses the fears in admitting you don't know about something, but I also think it's fair to attack the validity of the question itself assuming the original question was asked in a similar way to how it was presented.

This question could be considered a leading question, especially when considering the context: I don't write CSS at all, and never have heard of it - why are you assuming I know what it is? I regularly write CSS, but don't know how to use Saas - why are you assuming I use Saas and find it useful? I've used Saas in the past, find it confusing, and have decided to stick to CSS - why are you assuming a tool you use is a tool I should also want use and like?

Just ask the question in a way that doesn't make assumptions!
