Working on a team isn’t everyone, all at once, diving in together, communitas programming. Often times, it’s serial: first an architect designs a solution, a sole contributor might make the big technical decisions, someone else builds out a prototype, another person might set up the dev environment, a small team might do the initial development, others come in to make contributions late in the game, and some human on the other side of the continent is tasked with maintenance releases. The structure and conventions of code facilitate this cascading contribution.
Not CSS. Maybe because CSS was considered to live on the design side of the presentation layer, or maybe because it’s declarative, CSS development wasn’t talked about or followed in a predictable manner. Opening a CSS production file can feel like being knocked over and suffocated by a mudslide. So after years of treating CSS like the bastard child of the code base, we had no other choice than to devote time and thought to ridding the world of spaghetti CSS and classitus CSS.
Like so many conventions, frameworks & architectures, how to construct CSS is up for discussion. Some ideologies are better than others; some have stood the test of time; and some are good enough.
For me, it’s important for the team to know what’s going on, to communicate toward success, and to look forward to diving into the code at every stage of the project. When a project forms, everyone can help adopt the right CSS method for the group, and warn each other about gotchas.
“Never doubt that a small group of thoughtful, concerned citizens can change the world. Indeed it is the only thing that ever has.” — Margaret Mead
Well, right about now, we’re getting so advanced with CSS, deconstructing and renovating it, that some implementations are not even using it! But for these new methods to help us in daily production, we need to have a common background. And yet, there doesn’t seem to be a list of resources on the web for advanced CSS topics. Content marked “advanced” is frequently some experimental idea — that some day may become standard practice. Developers need pro CSS help for today’s project.
So I thought I’d start culling the advanced topics out of the large body of introductory and tutorial content. This list is not extensive, by far. I’m just beginning to gather the wisdom in one place. But if you’re a developer who is comfortable with coding CSS at a basic level, I hope this list will save you some time.
