This is why we need an
nth-letter selector in CSS .

I love React. I love how server side rendering React apps is trivial because it all compiles down to vanilla HTML rather than web components, effectively turning it into a kickass template engine that can come alive. I love the way you can very effectively still do progressive enhancement by using completely semantic markup and then letting hydration do more to it.
I also hate React. I hate React because these behaviours are not defaults. React is not gonna warn you if you make a form using divs and unlabelled textboxes and send the whole thing to a server. I hate React because CSS-in-JS approaches by default encourage you to write completely self contained one off components rather than trying to build a website UI up as a whole. I hate the way server side rendering and progressive enhancement are not defaults, but rather things you have to go out of your way to do.
And if you want to adjust the front-end code, you’ve got to set up all this tooling just to change a
div to a
button. That’s quite a barrier to entry.
In elevating frontend to the land of Serious Code we have not just made things incredibly over-engineered but we have also set fire to all the ladders that we used to get up here in the first place.
I love React because it lets me do my best work faster and more easily. I hate React because the culture around it more than the library itself actively prevents other people from doing their best work.

When I talk about evaluating technology for front-end development, I like to draw a distinction between two categories of technology.
Personally, I’m much more interested and excited by the materials than I am by the tools. But I think it’s right and proper that other developers are excited by the tools. A good balance of both is probably the healthiest mix.
I’m never sure what to call these two categories. Maybe the materials are the “external” technologies, because they’re what users will interact with. Whereas all the other technologies—that mosty live on a developer’s machine—are the “internal” technologies.
Another nice phrase is something I heard during Chris’s talk at An Event Apart in Seattle, when he quoted Brad, who talked about the front of the front end and the back of the front end.
I’m definitely more of a front-of-the-front-end kind of developer. I have opinions on the quality of the materials that get served up to users; the output should be accessible and performant. But I don’t particularly care about the tools that produced those materials on the back of the front end. Use whatever works for you (or whatever works for your team).
As a user-centred developer, my priority is doing what’s best for end users. That’s not to say I don’t value developer convenience. I do. But I prioritise user needs over developer needs. And in any case, those two needs don’t even come into conflict most of the time. Like I said, from a user’s point of view, it’s irrelevant what text editor or version control system you use.
Now, you could make the argument that anything that is good for developer convenience is automatically good for user experience because faster, more efficient development should result in better output. While that’s true in theory, I highly recommend Alex’s post, The “Developer Experience” Bait-and-Switch.
Where it gets interesting is when a technology that’s designed for developer convenience is made out of the very materials being delivered to users. For example, a CSS framework like Bootstrap is made of CSS. That’s different to a tool like Sass which outputs CSS. Whether or not a developer chooses to use Sass is irrelevant to the user—the final output will be CSS either way. But if a developer chooses to use a CSS framework, that decision has a direct impact on the user experience. The user must download the framework in order for the developer to get the benefit.
So whereas Sass sits at the back of the front end—where I don’t care what you use—Bootstrap sits at the front of the front end. For tools like that, I don’t think saying “use whatever works for you” is good enough. It’s got to be weighed against the cost to the user.
We’ve certainly seen that at Clearleft. We’ve worked on multiple React projects, but in every case, the output was server-rendered. Developers get the benefit of working with a tool that helps them. Users don’t pay the price.
For me, this question of whether a framework will be used on the client side or the server side is crucial.
That was a few years ago. I think that these days it has become a lot easier to make the decision to use a framework on the back of the front end. Like I said, that’s certainly been the case on recent Clearleft projects that involved React or Vue.
It surprises me, then, when I see the question of server rendering or client rendering treated almost like an implementation detail. It might be an implementation detail from a developer’s perspective, but it’s a key decision for the user experience. The performance cost of putting your entire tech stack into the browser can be enormous.
Alex Sanders from the development team at The Guardian published a post recently called Revisiting the rendering tier . In it, he describes how they’re moving to React. Now, if this were a move to client-rendered React, that would make a big impact on the user experience. The thing is, I couldn’t tell from the article whether React was going to be used in the browser or on the server. The article talks about “rendering”—which is something that browsers do—and “the DOM”—which is something that only exists in browsers.
So I asked. It turns out that this plan is very much about generating HTML and CSS on the server before sending it to the browser. Excellent!
I have misgivings. But just to be clear, these misgivings have nothing to do with users. My misgivings are entirely to do with another group of people: the people who make websites.
It wasn’t that long ago that devs coming from a Computer Science background were deriding CSS for its simplicity, complaining that “it’s broken” and turning their noses up at it. That rhetoric, thankfully, is waning. Nowadays they’re far more likely to acknowledge that CSS might be simple, but it isn’t easy. Concepts like the cascade and specificity are real head-scratchers, and any prior knowledge from imperative programming languages won’t help you in this declarative world—all your hard-won experience and know-how isn’t fungible. Instead, it seems as though all this cascading and specificity is butchering the modularity of your nicely isolated components.
It’s no surprise that programmers with this kind of background would treat CSS as damage and find ways to route around it. The many flavours of CSS-in-JS are testament to this. From a programmer’s point of view, this solution has made things easier. Best of all, as long as it’s being done on the server, there’s no penalty for end users. But now the price is paid in the diversity of your team. In order to participate, a Computer Science programming mindset is now pretty much a requirement. For someone coming from a more declarative background—with really good HTML and CSS skills—everything suddenly seems needlessly complex. And as Tantek observed:
Complexity reinforces privilege.
The result is a form of gatekeeping. I don’t think it’s intentional. I don’t think it’s malicious. It’s being done with the best of intentions, in pursuit of efficiency and productivity. But these code decisions are reflected in hiring practices that exclude people with different but equally valuable skills and perspectives.
Rachel describes HTML, CSS and our vanishing industry entry points:
If we make it so that you have to understand programming to even start, then we take something open and enabling, and place it back in the hands of those who are already privileged.
I think there’s a comparison here with toxic masculinity. Toxic masculinity is obviously terrible for women, but it’s also really shitty for men in the way it stigmatises any male behaviour that doesn’t fit its worldview. Likewise, if the only people your team is interested in hiring are traditional programmers, then those programmers are going to resent having to spend their time dealing with semantic markup, accessibility, styling, and other disciplines that they never trained in. Heydon correctly identifies this as reluctant gatekeeping:
By assuming the role of the Full Stack Developer (which is, in practice, a computer scientist who also writes HTML and CSS), one takes responsibility for all the code, in spite of its radical variance in syntax and purpose, and becomes the gatekeeper of at least some kinds of code one simply doesn’t care about writing well.
This hurts everyone. It’s bad for your team. It’s even worse for the wider development community.
Last year, I was asked “Is there a fear or professional challenge that keeps you up at night?” I responded:
My greatest fear for the web is that it becomes the domain of an elite priesthood of developers. I firmly believe that, as Tim Berners-Lee put it, “this is for everyone.” And I don’t just mean it’s for everyone to use—I believe it’s for everyone to make as well. That’s why I get very worried by anything that raises the barrier to entry to web design and web development.
I’ve described a number of dichotomies here:
- Materials vs. tools,
- Front of the front end vs. back of the front end,
- User experience vs. developer experience,
- Client-side rendering vs. server-side rendering,
- Declarative languages vs. imperative languages.
But the split that worries the most is this:
- The people who make the web vs. the people who are excluded from making the web.
