Frustration

I had some problems with my bouzouki recently. Now, I know my bouzouki pretty well. I can navigate the strings and frets to make music. But this was a problem with the pickup under the saddle of the bouzouki’s bridge. So it wasn’t so much a musical problem as it was an electronics problem. I know nothing about electronics.

I found it incredibly frustrating. Not only did I have no idea how to fix the problem, but I also had no idea of the scope of the problem. Would it take five minutes or five days? Who knows? Not me.

My solution to a problem like this is to pay someone else to fix it. Even then I have to go through the process of having the problem explained to me by someone who understands and cares about electronics much more than me. I nod my head and try my best to look like I’m taking it all in, even though the truth is I have no particular desire to get to grips with the inner workings of pickups—I just want to make some music.

That feeling of frustration I get from having wiring issues with a musical instrument is the same feeling I get whenever something goes awry with my web server. I know just enough about servers to be dangerous. When something goes wrong, I feel very out of my depth, and again, I have no idea how long it will take the fix the problem: minutes, hours, days, or weeks.

I had a very bad day yesterday. I wanted to make a small change to the Clearleft website—one extra line of CSS. But the build process for the website is quite convoluted (and clever), automatically pulling in components from the site’s pattern library. Something somewhere in the pipeline went wrong—I still haven’t figured out what—and for a while there, the Clearleft website was down, thanks to me. (Luckily for me, Danielle saved the day …again. I’d be lost without her.)

I was feeling pretty down after that stressful day. I felt like an idiot for not knowing or understanding the wiring beneath the site.

But, on the other hand, considering I was only trying to edit a little bit of CSS, maybe the problem didn’t lie entirely with me.

There’s a principle underlying the architecture of the World Wide Web called The Rule of Least Power. It somewhat counterintuitively states that you should:

choose the least powerful language suitable for a given purpose.

Perhaps, given the relative simplicity of the task I was trying to accomplish, the plumbing was over-engineered. That complexity wouldn’t matter if I could circumvent it, but without the build process, there’s no way to change the markup, CSS, or JavaScript for the site.

Still, most of the time, the build process isn’t a hindrance, it’s a help: concatenation, minification, linting and all that good stuff. Most of my frustration when something in the wiring goes wrong is because of how it makes me feel …just like with the pickup in my bouzouki, or the server powering my website. It’s not just that I find this stuff hard, but that I also feel like it’s stuff I’m supposed to know, rather than stuff I want to know.

On that note…

Last week, Paul wrote about getting to grips with JavaScript. On the very same day, Brad wrote about his struggle to learn React.

I think it’s really, really, really great when people share their frustrations and struggles like this. It’s very reassuring for anyone else out there who’s feeling similarly frustrated who’s worried that the problem lies with them. Also, this kind of confessional feedback is absolute gold dust for anyone looking to write explanations or documentation for JavaScript or React while battling the curse of knowledge. As Paul says:

The challenge now is to remember the pain and anguish I endured, and bare that in mind when helping others find their own path through the knotted weeds of JavaScript.

Whatever works for you

I was one of the panelists on the most recent episode of the Shop Talk Show along with Nicole, Colin Megill, and Jed Schmidt. The topic was inline styles. Well, not quite. That’s not a great term to describe the concept. The idea is that you apply styling directly to DOM nodes using JavaScript, instead of using CSS selectors to match up styles to DOM nodes.

It’s an interesting idea that I could certainly imagine being useful in certain situations such as dynamically updating an interface in real time (it feels a bit more “close to the metal” to reflect the state updates directly rather than doing it via class swapping). But there are many, many other situations where the cascade is very useful indeed.

I expressed concern that styling via JavaScript raises the barrier to styling from a declarative language like CSS to a programming language (although, as they pointed out, it’s more like moving from CSS to JSON). I asked whether it might not be possible to add just one more layer of abstraction so that people could continue to write in CSS—which they’re familiar with—and then do JavaScript magic to match those selectors, extract those styles, and apply them directly to the DOM nodes. Since recording the podcast, I came across Glen Maddern’s proposal to do exactly that. It makes sense to me try to solve the perceived problems with CSS—issues of scope and specificity—without asking everyone to change the way they write.

In short, my response was “hey, like, whatever, it’s cool, each to their own.” There are many, many different kinds of websites and many, many different ways to make them. I like that.

So I was kind of surprised by the bullishness of those who seem to honestly believe that this is the way to build on the web, and that CSS will become a relic. At one point I even asked directly, “Do you really believe that CSS is over? That all styles will be managed through JavaScript from here on?” and received an emphatic “Yes!” in response.

I find that a little disheartening. Chris has written about the confidence of youth:

Discussions are always worth having. Weighing options is always interesting. Demonstrating what has worked (and what hasn’t) for you is always useful. There are ways to communicate that don’t resort to dogmatism.

There are big differences between saying:

  • You can do this,
  • You should do this, and
  • You must do this.

My take on the inline styles discussion was that it fits firmly in the “you can do this” slot. It could be a very handy tool to have in your toolbox for certain situations. But ideally your toolbox should have many other tools. When all you have is a hammer, yadda, yadda, yadda, nail.

I don’t think you do your cause any favours by jumping straight to the “you must do this” stage. I think that people are more amenable to hearing “hey, here’s something that worked for me; maybe it will work for you” rather than “everything you know is wrong and this is the future.” I certainly don’t think that it’s helpful to compare CSS to Neanderthals co-existing with JavaScript Homo Sapiens.

Like I said on the podcast, it’s a big web out there. The idea that there is “one true way” that would work on all possible projects seems unlikely—and undesirable.

“A ha!”, you may be thinking, “But you yourself talk about progressive enhancement as if it’s the one try way to build on the web—hoisted by your own petard.” Actually, I don’t. There are certainly situations where progressive enhancement isn’t workable—although I believe those cases are rarer than you might think. But my over-riding attitude towards any questions of web design and development is:

It depends.
