I've been coding HTML and CSS for the last 7 years, more heavily at times than others. To me, code is more than instructions to be computed. It's a language that can be spoken and it's how well it's spoken that makes the difference between good code and bad. Semantics, formatting, namespaces, weight, all contribute to the quality of the code. Yes, many code problems can be solved a thousand ways, but very few of those will actually make sense.
Problem: Consolidate UI components across multiple applications.
Solution: Meeting on a weekly basis, I collaborated with UI designers to document the HTML and CSS requirements for each interaction pattern, from page layouts to custom select menus.
