I am a beginner and I totally agreed with you!
I am struggling to restyle my old websites to apply what I am studying in these months, but after a quick start, I always end up to stuck my self on web design aspects than coding aspects.
It is about a week that I am thinking of it. How much important is the graphic aspect?
If I have to build a website all by myself I can understand that the graphic part is an important step, but if I wanted to be only a front-end developer working for a company where that already have a web designer?
