I'm a graphic designer trying to learn more code to transition towards becoming a web/mobile/interactive designer. I am also trying to brush up on my Dreamweaver skills. Besides the obvious HTML/CSS, what programming language would you expect one to know with a job description mentioning the following: "This role is expected to be versed in relevant graphic design software and development code, including HTML and CSS. Plus would be experience in e-commerce, social media and mobile"? I'm teaching myself more about responsive and fluid web design, but trying to make sure I'm not missing something else that is common as a web or mobile designer.Thanks!
