Back-end or front-end,which one do you preffer and why?(I want to know to start in one of these sides)

Answer 1

Before learning back end, you must understand HTML and CSS.

Answer 2

Hello. It's not about preferences because you need both to do a good functional website. But you need to start with front-end (html, javascript) before, cos ussually you use back-end to generate dynamic front-end code (php, mysql, etc).
