I'm currently self-learning development with the intention of a career change. I'm 28 and it's rather overwhelming the amount of things I feel I need to pick up, but I'm getting there, slowly.
With that said, I do feel it's important I get a good handle on HTML/CSS but my question is really, just how much is necessary?
I've knocked together a basic site with what I've learned so far (HTML/CSS), and wondered if I could get some feedback as to whether that's an adequate working knowledge to continue focusing on the development side?
I've put it up as a kind of temporary test site on my domain, please excuse the design as I'm not a designer at all, and definitely not a UX expert.
