If your skillset is HTML+CSS, I think you can still be more of a developer than a designer. Someone else gives you mockups and you implement them. HTML+CSS can get you pretty far in a lot of cases without any JS required, though since HTML5, the spec includes interfaces to the Javascript APIs, as well as a whole bunch of stuff for accessibility. I enjoyed this post from a few months ago which helps give you a sense of the depth of HTML: https://news.ycombinator.com/item?id=27080348 https://news.ycombinator.com/item?id=27080348 . This person didn't even dive into the spec, just the MDN docs. To contrast this, a designer is someone who does things like visual branding and consistency, creating assets like logos, background images, maybe even vector graphics, and device breakpoints. HTML and CSS are also complex enough that you can even spend a significant time specializing in one/both.
