Please note that I am primary a designer who is often responsible for coding as well. In my experience every client comes with different requirements, environments, and stack preferences. Thus, I suggest learning CSS first and everything else will fall into place. That way you'll be able to adapt to a variety of situations. With that said, if you do have a solid working understanding of CSS, you'd be in the upper percentile of front-end developers that I come in contact with on a daily basis. Not many that I have interacted with know their way around CSS very well.
