Last month I went to CSS Day in Amsterdam, as an attendee this year, not a speaker. It was an excellent conference comprising the titular CSS day and a Browser API Special the day before.

By the end of CSS Day, my brain was full. Experiencing the depth of knowledge that’s contained in CSS now made me appreciate how powerful a language it is. I mean, the basics of CSS—selectors, properties, and values—can be grasped in a day. But you can spend a lifetime trying to master the details. Heck, you could spend a lifetime trying to master just one part of CSS, like layout, or text. And there would always be more to learn.

Unlike a programming language that requires knowledge of loops, variables, and other concepts, CSS is pretty easy to pick up. Maybe it’s because of this that it has gained the reputation of being simple. It is simple in the sense of “not complex”, but that doesn’t mean it’s easy. Mistaking “simple” for “easy” will only lead to heartache.

I think that’s what’s happened with some programmers coming to CSS for the first time. They’ve heard it’s simple, so they assume it’s easy. But then when they try to use it, it doesn’t work. It must be the fault of the language, because they know that they are smart, and this is supposed to be easy. So they blame the language. They say it’s broken. And so they try to “fix” it by making it conform to a more programmatic way of thinking.

I can’t help but think that they would be less frustrated if they would accept that CSS is not easy. Simple, yes, but not easy. Using CSS at scale has a learning curve, just like any powerful technology. The way to deal with that is not to hammer the technology into a different shape, but to get to know it, understand it, and respect it.
