Tell that to a decent number of people I have worked with over the past 20 years. In fact, I know people to this day who have been writing CSS for decades who don't really know fundamental things like specificity, inheritance, or the cascade. Pattern matching into the sunset, not a single fundamental piece of CSS specifications ever internalized, still getting paid (its okay).
I tried to use a framework on a web project recently, but looking at the two most popular frameworks... one of the results in every site looking the same, while the other is a step backwards to the bad old days in the worst possible ways. It was simpler to start from scratch, and I finally understood the cascade. I was actually able to drop most of the explicit class attributes, which led to a significant reduction in page size.
The primary purpose of frameworks was to work around the quirks in all the different web browsers out there, and to implement grid-like layouts before we had css grid, and to deal with the impossibility of centering a div natively. None of that is necessary these days, and hasn't been for a decade.
Atomic CSS is great. It does abuse class="" in the same way style="" was abused. It's counter-intuitive but the obvious code smells produced here are better than the non-obvious code smells created by other style architecture approaches.
I've always now-and-then packaged up and open-sourced the pattern I use for CSS. The projects have gotten smaller and smaller. This reflects well on CSS as a technology.
I think class="" has more to offer in an information density sense. There's more potential there than style="" had. Instantly lumping them together was my first response too, but I was wrong. The in-the-HTML shorthand of frameworks like Bootstrap/Tailwind/CASS is insanely useful in a way that inline styles never were.
One reason I think Tailwind became so popular is that it makes it much easier to pattern match CSS. I don't think it's a good or bad thing, it's just a thing.
Yeah, I am not saying its bad in all applications, just that people who use CSS these days rarely really know CSS (who can know it all?), which isn't really any different from the past on a general level. Yet, I think we should push our peers to view the entirety of CSS as meaningful and worthy of attention.
I'm forcing myself to use raw CSS in my recent work just so I can gain a better understanding of it. It's nice what you can achieve without JS, but man sometimes it just feels like arranging arcane symbols until you achieve the desired result.
All just to say, w.r.t. CSS, if you are doing this, you don't really understand what you are doing, why browsers added a feature, what the language is, you are just replicating patterns because you saw other people do it.
I never got very good with CSS or HTML styling. I know enough to generally fix obvious stuff, but I'm kind of a luddite and still use Bootstrap for most of my stuff. I've mostly stopped doing web stuff, so the only time I touch CSS is when I'm doing an admin screen or something, so it doesn't have to look great.
Still, a part of me wonders how different my life would be if I had taken to frontend programming enough to make things that look nice. It's not like there isn't anything enjoyable about it, I just ended up taking to backend distributed systems work a bit sooner.
The book has a lot of content over what to make pretty and what not to make pretty. I think knowing what not to bother with is an underrated skill. A lot of what inspired me to write it was backenders handing off markup that they tried to make semi-passable. Unstyled HTML, please!
Big problem with evergreen standards: if you try to come back to a standard that is now twice as big but still has the same version number, there is nobody writing books to teach you what you missed out on. Want to come from CSS2 to 3? They got you. Want to do backend development for five years and then get a summary on what you missed? Go fuck yourself.
I'm not saying that this is a "bad" thing, but the last time I did any significant amount of frontend stuff was back in ~2014, and it was AngularJS, which was considered pretty ok at the time I think. I left that job and started doing almost exclusively backend stuff for several years, and when I looked back, the entire world had switched to React and transpiling JSX and a lot more CSS than I was familiar with.
It seemed pretty intimidating to try and pick that up again, so I never really left the backend stuff, and now I've managed to even avoid web stuff for awhile, because I kind of hate web programming.
Forgot that you can nest CSS now without Less or SCSS. Luckily my CSS has just barely tipped over into 'hot garbage' when I figured this out instead of in another four weeks.
I detest writing CSS and HTML. I just find it boring fiddly and annoying. I have started doing "vibe" coding with LLM's. Giving a decent prompt produces results that are... pretty good.
Almost 100% in lighthouse for both mobile and desktop, responsive, reusable components, dark/light mode and a design that was better than I could do in the 2-3 hours I spent doing it (while sipping wine).
I know its not a solution for everyone, and probably won't work for the prettier designs out there, but you can go a long way with these tools this day.
I know there is a reluctance to not use LLM's for code tasks, and I am one of the largest critics, but for me this solves a real pain point. I don't want to write CSS/HTML anymore and these tools do a good enough job of it that I don't have to.
I agree. CASS (the library this book was promoting) is actually really great paired with LLMs. If I revisit this project, it'll be along the lines of using it with LLMs.
HN Confessional: I wrote a custom theme for my server management software a few years ago that's basically just a rewrite of the stock theme's rather large CSS file. Among a little more than 1200 lines, I include `!important` 175 times. I imagine that causes hives among our more discerning front-end devs.
It looks great, specifically for me. I can't comment on anyone else, but I have to imagine it's dysfunctional. I abstracted as many color and style options as possible to allow for a lot of variable-setting. I unreservedly apologize for the affront to common decency (but I'm probably still gonna use it). Gotta have that transparent glass effect on ma' netstats.
And the fix is another framework, because of course it's another framework. Frameworks are to CSS what greige paint is to a house. Trying to implement the missing 5% of a CSS framework without knowing how to implement "complex" CSS from the ground up means you are never implementing the missing 5%. Your site or app or whatever is just going to look like every other site that uses that framework.
Now that CSS is more or less feature complete and the fact that there's just one web browser means you don't need the clever tricks rolled up in a framework to center a div or to have a grid layout that works without resorting to tables. It's literally part of the CSS spec and has been implemented in every browser for a decade now.
The argument I make in the book is that the last 5% of CSS/design should be written by people who can write CSS. Nobody else should even be writing CSS because it turns into a huge mess when everyone jumps in.
I mothballed this project because people were so incredibly cruel about it (a CSS project!). Remember that people who work on this stuff are people, and we're just trying to make things better. Also, you can pry .vertical-center from my cold, dead hands.
How do you expect anyone to learn CSS if they're being told to not even think about writing CSS unless they already know CSS? The whole premise demotivates learning. Experts weren't always experts. They had to start somewhere. If the world were to follow your advice, CSS would soon become dead knowledge. I am absolutely perplexed that you could write something, an act of conveying knowledge, and that you wanted to convey "don't learn this". Do you not see how weird that is?
Yep, it's weird and controversial. That's why I wrote a book explaining it and used a pseudonym.
Now: ~60% of devs know some CSS, rest feel guilty
YSAC's pitch: ~10% of devs know lots of CSS, rest avoid it without guilt (they suck and that's okay)
I guess 0% would mean a dead CSS, so it's closer to dead, sure.
If you get a more powerful saw, you can either cut down more trees or you can spend less time cutting down trees. CSS is a more powerful saw now. I'm suggesting spending less time cutting down trees instead of cutting down more trees.
Learning how to properly use a chainsaw is of use to more than just those in the logging and treecare industries. Nobody is going to call me to remove that tree that's endangering a historic building or to cutdown a few hundred acres of raw toilet paper, but I still need to understand how and when to sharpen the chain if I'm going to be cutting down trees on my own land for use as firewood.
I think you would have had significantly less blowback if you approached the subject from a positive angle. I know you were probably attempting to be humorous, but it just comes off as something wrong.
That sort of humor is best left for the experts...
> The last big driver of time-wasting in CSS is the drive for pixel perfection
I agree. Also users/product managers do not care. They will see UI that is a little bit “off” and think negatively about your brand. Congrats, now you have a ticket to make the UI look pixel perfect.
I suppose the audience for this isn’t people who actually get paid to write CSS, but instead casual blog writers. It’s definitely ok and normal to have little blips on your side project.
The perfection should be downstream of the project's coded standards, not downstream of the faithful implementation of the designer's work. Some designers are really good about maintaining standards-- but the book would argue all that effort should be spent elsewhere.
It's basically "the arbitrary padding the designer liked in the moment" vs. "the standard padding that's everywhere in the project." This book argues you should always use the standard padding. Your product should be pixel-perfect, just not in the PSD-to-HTML sense.
> It's basically "the arbitrary padding the designer liked in the moment" vs. "the standard padding that's everywhere in the project." This book argues you should always use the standard padding. Your product should be pixel-perfect, just not in the PSD-to-HTML sense.
Oh yeah - I remember my first job things had to be pixel perfect to what the boss had mocked up in Photoshop. Thankfully at my next job it was just use whatever the project's CSS gives you unless it looks terrible.
I don't do much frontend any more but my current marketing team is happy with anything that looks reasonable.
On the other hand, personal sites and side-projects are where you can afford to take as much time as you want in order to achieve pixel perfection without the pressure of shipping anything.
I recently started a green field project using copilot and tailwind. I’m blown away by how good ai is with css. I’m just glad no one has to try wrestle with css like we did back in the days.
CSS styling used to take me forever, now I basically just tell AI the contours of what I want, and it gives me the vast majority of what I want. It often has some bugs, and I always need to edit/tweak it to get things right, but it probably saves me 90% of the time I used to waste on CSS (I'm primarily a backend dev).
Edited the year into the title. CASS (the CSS library) and YSAC (this book) have been a huge marketing mess, to be honest. And yeah the substack was part of it-- I think the book came first though. Kyle Yeats (rhymes with stylesheets) was going to be a Youtube persona but I could never really get the feel of it right.
The book morphed into being more about project management. I think there's a lot of value in it still, in that respect, so I'm putting it all online for free.
I enjoy working with CSS immensely. It takes some thought to get things right from the beginning, but I find it's always clear what can be done to improve it.
With modern features like CSS nesting, anyway; just a few years ago when IE support and whatnot was more relevant it was a different story. Now you can just throw everything into a flexbox.
Why? Just ask an LLM if your taxonomy skills are weak. They'll transfer eventually.
Things like BEM give you the most flexibility for extension, things like atomic CSS (tailwind) give you the most velocity for not giving a fuck about ever touching the markup again.
There’s a reason everything I’ve done in the last 5 years uses bootstrap. And doesn’t have to look like bootstrap. Our internal graphic designer loathes bootstrap and didn’t recognize I had used it until I told them.
Hot take: you suck at CSS because you never bothered learning it.
A long time ago, everyone in my team kept making excuses why they hate css. I went to Lynda.com and found a pretty good class. I can't remember the instructor, but it was so good that I still use the same patterns more than a decade later. I tried to get the whole team to take it, but no one wanted to. "It's a waste of time", "It's not even a programming language."
They built all kinds of tooling around css, trying to avoid css. We had dormant css that no one could ever figure out if it was used, we had important and position absolute everywhere. Today, it's not so different. You see divs with 20 or 30 classes in them.
Just learn css. Any class is better than no class.
My view is that those who designed CSS suck when it comes to designing intuitive systems.
I would not advocate constraint solvers, in the future I hope ViTs are so cheap to run that they can infer the right layout of things at any orientation and size in single digit milliseconds, solving the layout problem for good =)
Organic growth leads to vestigial warts - that is the price of success and development. I'm really impressed with so much of CSS and what can be achieved with what it has become.
> My view is that those who designed CSS suck
I think that is a stink attitude because there is no need to malign people. Don't be a dick. Most successful things "suck" because it is easy to feel the compromises when you use something. It is incredible hard to see the warts before we build, and even harder to find consensus solutions. All too often I hear whingers, that lack the ability to deliver working solutions, who are often unrealistically idealistic and too quick to poopoo the work of others. They are the people with second-system syndrome - who often deliver a version 2.0 using technology B and get an outcome all too often far worse than v1.0.
Agreed that there is no need to be a jerk on this discussion. The points you make are generally true in the abstract, but we are talking about CSS here which really is one of the most convoluted and confusing pieces of UI software out there. And the problems are not cruft from success and time: the core parts of the spec are terrible and confusing. The basic idea of a Cascade is a bad idea for a variety of reasons and nobody uses this feature if they can avoid it. The over all layout spec is really convoluted and requires you to figure out the difference between absolute and fixed position and top vs bottom. (Making a horizontal row of images is shockingly difficult). There is also a whole system of units for "absolute length" that are defined in relation to the inch (including the terribly named pixel which is 1/96th of an inch (inches being defined for printers but not for screens). These are issues were all features of the very first release. The later updates have provided alternatives, but the core spec sets people up to fail.
It is so easy to look backwards and imagine a better world and then moan about imperfections. You can do that with absolutely any technology.
Most of your complaints have been solved, or there are best practices that avoid the downsides.
> Cascade is a bad idea for a variety of reasons
CSS is fucking genius. It is flexible enough that we have solutions that avoid the problems. I love the idea of an alternate universe where we do a redesign: but personally I'm very unfond of some of the (now rightly dead) systems designed to "fix" CSS.
> The over all layout spec is really convoluted
The domain is difficult: we just think it could be simplified because we are given CSS and so we think we could improve upon it.
> absolute
Don't use it. It's a bad design smell. Rarely needed in a few corner cases. A nightmare before getBoundingClientRect() was reliably usable (a decade ago)
> fixed position
Is damn fucking awesome! I developed butter smooth fixed/sticky positioning that worked in IE5.5 to IE11 using absolute instead. I developed a zero-jank fixed position feature in IE but there were insanely complex requirements (global order of events with DOM updates plus needs extremely complex techniques to deal with viewport scrollbars - only a stubborn idiot engineer like me would attempt to yak shave it but I solved it).
fixed positioning was hell in early iOS (broken zoom, broken events, broken inputs, jankyness, scrolled offscreen). Let's not talk about early Android browsers. Arrrgh fixed positioning (and everything else) was broken in Edge (Spartan/Legacy). Yet fixed positioning is a critical feature for mobile screens - a major new feature that CSS managed to embrace.
> Making a horizontal row of images is shockingly difficult)
That's what a <table> was for. Many people searched for difficult solutions: no surprise that they had troubles of their own making. Now solved in more flexible ways with modern CSS layout features (there's that amazingly flexible capability of CSS to absorb new features again!)
> units for "absolute length" These are issues were all features of the very first release.
Which was used because we didn't have modern high resolution screens. Layout units are just extremely difficult (demonstrated by the variety of different units we now have - made available by more powerful computers).
It is just too easy to use 20/20 hindsight to criticise every historical decision.
I feel your pain: I dealt with every quirk in every browser for far too many years.
It is healthier to thank the people that worked on the specifications: awesome technology that is astonishingly flexible (and quite frankly amazingly backwards compatible). Yes, you need to learn how to use the features. No, that isn't a problem. Most anti-features can now be ignored when developing a greenfield site.
I'm extremely thankful that I never have to make a page work on IE (or many other now obsolete browsers) ever again.
There are a huge list of awful gremlins in CSS you didn't mention - luckily most developers can avoid the nastiest of them (zoom: 1; to fix layout?). There are also some truly inspiring CSS features: declarative transitions and animation seem like magic to me (complex, but deliver amazing results) with hidden risks of course: https://news.ycombinator.com/item?id=43259722
I guess CSS is the worst form of layout language except for all the others that have been tried.

You can read this and know most things about CSS. For a bit anyway. You'll forget things you don't use. You might remember them again one day.
