I work as a product designer and UI developer, but I'm leaving my company soon and we are trying to find a UI developer to replace me. However this process is making me realize just how few people actually promote themselves as CSS experts. Everyone claims to be a front-end developer focusing on JS, and mention their CSS abilities in passing, rarely even being specific about SASS/LESS/whatever abilities.
We have great JS front-end developers, what we need are people who REALLY know CSS, layout, best-practices, performance, etc. Where do I find these people? What are they called? Why is this skill-set seemingly so unpopular?
