So I'm a young lad with a career in Front end development I love coding in HTML (yes I know it's not a coding language to some, but to a computer illiterate person it's wizardry so I've got that going for me) I've got skills in responsive design with css and skills in javascript, jQuery and a little bit of skill in PHP But I'm not sure what to go for next? I'm not much of a back end developer..got nothing against it, just never was my cuppa tea. I want to improve my skills but I'm not sure what to look into.. Any advice?
