Creating 3D scenes with CSS has always been possible[0], but like this project, it's required JavaScript for interactivity.
But there's a lot more CSS features now. While in the past, Turing completeness in CSS required humans to click on checkboxes, now CSS can emulate an entire CPU without JavaScript or requiring user interaction.[1] So I wonder if DOOM could be purely CSS too, in real time.
> Yes, Lyra Rebane build a x86 CPU completely in CSS, but that technique is simply not fast enough for handing the game loop. So the result is something that uses a lot of JavaScript.
I feel obliged to repeat my assertion that this evolution of CSS was inevitable and foreseeable and that the HTML Editorial Review Board should’ve chosen DSSSL in the first place.
Even better, since everything is well organized, you can add `opacity: 0.7` to `.wall` specifically, and get something that looks almost exactly like how old school wallhacks looked like.
A wall hack is any technique allowing the player to see opponents through walls. Googling for screenshots or videos should give you a good idea of how it looks.
Works smoothly in Firefox. But the default key mapping is busted: fire at Alt means that it opens and closes the menu in Firefox with each press. Also, Alt + left arrow ends the game and goes back in history.
Interestingly, it was more choppy in Chromium.
I could not find a key for moving sideways ("strafing").
Firefox's WebRender is truly a great creation. While Chrome is faster at most things especially involving JS, Firefox puts so much of its rendering on the GPU so moving elements around is incredibly fast.
Strafing is implemented on A and D at least, but having one hand on the arrows to turn and WASD to move is a bizarre mix of modern and original controls
This feels like one of those “because we can” projects that accidentally reveals where the platform is going.
CSS started as purely declarative styling, but between things like conditionals, math functions, and now these rendering tricks, it’s slowly creeping into “programmable system” territory. Not because it’s the right tool for it, but because browsers are becoming the real runtime. The interesting question isn’t “can Doom run in CSS”, it’s how much logic we’ll keep pushing into layers that were never meant to handle it.
The design of CSS has always been weak IMO. What we needed were general, simple primitives that can describe layout relationships and a compositional layer that includes some common defaults.
The question is really about where the boundary between presentation (CSS) and interactivity (JavaScript) lies.
For static content like documents the distinction is easy to determine. When you think about applications, widgets, and other interactive elements the line starts to blur.
Before things like flex layout, positioning content with a 100% height was hard, resulting in JavaScript being used for layout and positioning.
Positioning a dropdown menu, tooltip, or other content required JavaScript. Now you can specify the anchor position of the element via CSS properties. Determining which anchor position to use also required JavaScript, but with things like if() can now be done directly in CSS.
Implementing disclosure elements had to be done with a mix of JavaScript and CSS. Now you can use the details/summary elements and CSS to style the open/close states.
Animation effects when opening an element, on hover, etc. such as easing in colour transitions can easily be done in CSS now. Plus, with the reduced motion media query you can gate those effects to that user preference in CSS.
It's abstraction inversion at its finest. Declarative styling sounded like a good idea, but it jumped the shark long ago. It's begging to become a real programming language but for some reason the design ethos behind CSS seems to have been avoiding programming at all costs--maybe that's to keep the browser renderer in control (and hopefully responsive), maybe it's because they didn't want designers to have to learn to program, maybe they just hate JS. Whatever the reason, it's clear that CSS took a wrong turn and mutated into absolutely the wrong abstraction.
Great example as to why people are yearning for CSS in TypeScript. Something as simple as if() only works in Chrome and there's not a good shim story for CSS versus a more complete language, so you end up with this:
> The problem: CSS can compute a number – 0 for visible and 1 for hidden – but you can’t directly use that number to set visibility. There is a new feature coming to CSS that solves this: if(), but right now it only just shipped in Chrome.
> So I used a trick called type grinding. You create a paused animation that toggles visibility between visible and hidden. Then you set the animation-delay based on the computed value to determine which keyframe is used:
> A negative animation delay on a paused animation jumps to that point in the timeline. So a delay of 0s lands in the visible range, and -0.5s lands in the hidden range. It’s a hack, but a functional one. When CSS if() gets wider support, we can replace this with a clean conditional.

I feel there should be a gov dep where all the "i turned this into DOOM" folks get hired, to build the next spicy interplanetary propulsion systems. They are clearly needing an exotic task to stop twiddling their fingers.
At this point, I’m just waiting for someone to implement a CSS-only browser inside this CSS-only Doom, so we can achieve full recursive insanity. The 'Can it run Doom?' meme has officially transcended hardware and entered the realm of pure Turing-complete masochism.
Within a week they would have a rocket prototype where you can plug in a mouse and keyboard and play doom on the exhaust flames by mixing different fuel chemicals.
Someone wrote an x86 emulator with CSS (it uses JS only for clock to make it more reliable). https://lyra.horse/x86css/ . So, CSS is officially Turing complete (which is a bit scary IMHO).
I think it would be too easy to create an uncontrollable cascade of function calls, causing terrible performance. IMO, it's best to keep concerns separated. Perhaps the current JS/DOM interface is a bit cumbersome, but it gets a lot done. What is your reason for merging?
Good question, I personally think that seperating by concerns is good. But when problems arise like boundaries that get crossed or compilers implementing language features into css like Sass, maybe it proves that those things are actually not two concerns but one.
Lately I am using Catch2 (a c++ testing framework) and wanted to benchmark some code. My first instinct was looking for a benchmark framework. But to my surprise Catch2 does also have a benchmarking framework included!.
Most people would argue that a testing framework should not include a benchmarking framework. But using it myself it showed me that both concerns of benchmarking for performance regressions and testing are similar.
Similar enough that I would prefer both of them together.
Most people, me included, are asking: "Should this be split into more?" But seldom, we ask: "Should this be merge into one?"
just a small note on this very cool implementation and write up. you wrote modeling tools and animation stuff has camera that moves around.
i think ultimately, there also the world moves aroun the player and cameras are just a concept to make the frustrum etc (maybe modern tools do it differently, im a little out of date)
In recent years CSS has become closer to a full programming language through experimental features, for example in 2025 they added if statements and some math functions like modulo
It's not just closer. Someone wrote an x86 emulator with CSS (it uses JS only for clock to make it more reliable). https://lyra.horse/x86css/ . So, CSS is officially Turing complete (which is a bit scary IMHO).
I like the declarative nature of it. It makes it so easy to debug anything, with "simple" introspection tools. I feel that many horrors will be created when we introduce control flow to CSS.
And this project kinda show how far you can go, still, if you really want it :D
I was amazed when I first came across CSS scroll snapping. It's great for creating immersive experiences where one part of the page fills the entire screen while native browser scrolling still works.
Yes, and in most cases it's perfectly valid not to interfere with scrolling. The nice thing about CSS scroll snapping is of course that the browser still handles it (instead of it being taken over by JS).
The demo really does not work in Brave. I use vertical scroll snapping on the landing page of one of my projects (enabled for screens with a min width of 768px and a min height of 600px - should work in Brave): https://cybernetic.dev
In 2006, Ars Technica published an April Fool's article[0] declaring that the perennially-forthcoming Duke Nukem Forever would finally see the light of day... as... a browser game! Ho ho, how droll.
Crazy that the future of software development now looks like we'll all be making UIs with specs that just a few years ago didn't allow you to trivially center a widget in a container.
I opened the article and read the first paragraph. Then skimmed the rest.
As others pointed out: the fact you can do this in CSS tells you everything you need to know if you consider what CSS is for. Even w/o ever looking at the spec or understanding how it came to be.
i don't see what you mean? it's a rendering technology
i guess if you're someone still stuck on the "web browsers are for displaying static documents" and "css is for prettifying markup" thing, then sure, I bet what you said sounds real witty
While standalone CSS is not yet Turing complete, I worry about the new attack vector categories opened up by moving it towards that state. Already I believe attackers have a choice to spread the attack payload between CSS, HTML and JavaScript to evade current detectors and analysis at the network borders, and evade CSP's since we're well into undecidability territory, like using CSS attribute selectors if the CSP allows external images or fonts. But I'm far from proficient at web browser red teaming. Is this worry unfounded?
> "I used Claude to create an approximate version of the game loop in JavaScript based on the original DOOM source"
This is the real horror here, Uncanny-Valley gameplay Doom. It's like those Doom maps where people tried to recreate the game levels from memory, but still made a few mistakes and got some details wrong. This is like that, but for the gameplay rather than the level layouts. It's different enough to be wrong.
We have Green Armor that sets your armor to 200%. Health Bonuses that reset your health to 100% if you exceeded that number, too bad if you recently collected a Soul Sphere. Switch-activated doors that are supposed to stay open, but instead automatically close, but then the secret wall unexpectedly activates like a manual door.
This is so disingenuous. You literally clipped the full sentence that changes the context significantly.
> "Once I’ve proven to myself that rendering was feasible, I used Claude to create an approximate version of the game loop in JavaScript based on the original DOOM source, which to me is the least interesting part of the project"
This post is about whether you can render Doom in CSS not whether Claude can replicate Doom gameplay. I doubt the author even bothered to give the game loop much QA.
Couldn't agree more ... Especially how platforms like Stitch 2 are eliminating the barriers for non-technical individuals to actually get pretty decent UI/UX experience ..
The fact that Claude is killing CSS officially means we need to switch back to IRC or something. AI is a parasite we cannot integrate but only avoid. (P.s. if you work in AI, stop, you are literally destructive to humanity.)
I ran calypso.z3, tristam_island.z3 and a few more Zmachine text adventures under an interpreter created in PostScript.
Also if I want I can cross-compile a static build of Frotz for Linux/Misc and emulate it under a RISC interpreter for Linux syscalls written in... Perl, runable in every modern Perl port out there. Linux/RISC binary under Perl for NetBSD/Vax? Yes. Slow? Not much, it's a text game in the end.
But, as for the ZMachine, you can run text adventures in Android,
Game Boy, Amiga, MSDOS, Windows, Palm PDA's... anything 8bit and up.
Also, damn Sokoban under Eforth written in Subleq, a VM which can just:
- set up a 2^16 RAM size
- single opcode: substract A from B, if less than 0, go to addr in C.
- A < 0? Get ASCII input in B
- B < 0? Put ASCII output in B
- C < 0? End
This, just this, and people wrote Subleq simulators in C, AWK, Python, TCL, FPGA's and whatnot. And it will run Eforth, and that means... you can write a
ZMachine interpreter on it and be really slow if emulated in a Pentium 4 (maybe 3/5 seconds per command with a ZMachine on top of Eforth for Muxleq instead of Subleq), but the game will be playable and a great exercise on Turing completeness.
If a Mandlebrot render under Muxleq+EForth (with no floats used, just integers) is as fast as a C64/Amiga with a native Forth. then having that tiny EForth+Muxleq is not that useless.
While running Doom on X is typically a show of personal hacking skills, and a display of the turing completeness/power of X,
I think that running Doom on X can also be a criticism of X, certainly the opposite of the intention in some cases. Consider a config mechanicsm, if I prove that I can run Doom on .md or .ini, or notepad.exe, most people should be concerned, not just for bloat, but for security reasons.
The value of some tech is precisely in what it cannot do, not just what it can do.
Is CSS that awesome? It's still a language designed for styling webpages with 30 year of added features. I'd argue something purpose built would be a much better tool for the potential usecases people try to use CSS for now.
I guess I am asking, if modern CSS is so awesome, it's awesome compared to what exactly?
I think the argument lies in its flexibility and versatility (regardless of it being the most efficient or effective tool for this one particular task).
Duct tape is awesome for the same reason -- even though there are several effective use cases for duct tape where a different tool would technically be "better" for the job.
No doubt the very loudly opinionated not-web-dev community, who have So Much To Say about web devs and web tech, have produced an uncontroversial, perfect layout system, styling system, and language to produce the replacement for this awful web tech. Where is it? What is it? Please provide (the better version of) a hyperlink to the docs.
There's decades of UI frameworks where the structure of the elements/widgets dictates the layout. HTML/CSS doesn't do that, because it is clearly made to style text documents, not UIs.
So yes I will argue that Qt6 and GTK are better than flexboxes.
I am not sure what a purpose-built tool would look like, but the CSS-like language you see in UI frameworks like GTK is tailored for styling actual UI's.
In CSS on the web, just centering a div has historically been a problem. We have flexbox now, but what if CSS was designed with our current needs from the get-go?
Creating 3D scenes with CSS has always been possible[0], but like this project, it's required JavaScript for interactivity.
But there's a lot more CSS features now. While in the past, Turing completeness in CSS required humans to click on checkboxes, now CSS can emulate an entire CPU without JavaScript or requiring user interaction.[1] So I wonder if DOOM could be purely CSS too, in real time.

So impressive! Bonus, you can wall hack by just deleting a div ahah
Even better, since everything is well organized, you can add `opacity: 0.7` to `.wall` specifically, and get something that looks almost exactly like how old school wallhacks looked like.
Is that a Doom reference? What’s a wall hack? How did it look?
A wall hack is any technique allowing the player to see opponents through walls. Googling for screenshots or videos should give you a good idea of how it looks.
I mean they literally just told you...
But where can I try it out in my browser?
EDIT: https://cssdoom.wtf/
My phone IMMEDIATELY got toasty as I started moving around the world :')
Never tried Doom on a phone before, this one is surprisingly fluid and very playable.
It works perfectly in Safari on mobile. this never happens.

All in all, quite mind-boggling.

I was amazed when I first came across CSS scroll snapping. It's great for creating immersive experiences where one part of the page fills the entire screen while native browser scrolling still works.
Personally, I find it to be a little disorienting. I get a bit of motion sickness with scroll snapping and I'm not exactly sure why.
When done right, I oddly find it immersive too. But know some people aren't fond of scrolling being tampered with.
The post here could really use it though. The main content is pushed to the bottom of the page!

Is CSS that awesome? It's still a language designed for styling webpages with 30 year of added features. I'd argue something purpose built would be a much better tool for the potential usecases people try to use CSS for now.
I guess I am asking, if modern CSS is so awesome, it's awesome compared to what exactly?
I think the argument lies in its flexibility and versatility (regardless of it being the most efficient or effective tool for this one particular task).
Duct tape is awesome for the same reason -- even though there are several effective use cases for duct tape where a different tool would technically be "better" for the job.
But you don't choose CSS, it's the only tool in the toolbox. As long as you stick to the Web.
I'm asking the same question!
No doubt the very loudly opinionated not-web-dev community, who have So Much To Say about web devs and web tech, have produced an uncontroversial, perfect layout system, styling system, and language to produce the replacement for this awful web tech. Where is it? What is it? Please provide (the better version of) a hyperlink to the docs.
There's decades of UI frameworks where the structure of the elements/widgets dictates the layout. HTML/CSS doesn't do that, because it is clearly made to style text documents, not UIs.
So yes I will argue that Qt6 and GTK are better than flexboxes.
Because you asked for it, here's some documentation to a UI framework which I believe to work better than the web stack: https://doc.qt.io/qtforpython-6/PySide6/QtWidgets/index.html
I was writing CSS +20 years ago and it's never been better.
What kind of system would you propose (or do you envision) for applying visual styling to HTML markup in modern web pages today?
You can keep it high level but your comment makes me think you have something in mind, and I'm honestly curious.
I am not sure what a purpose-built tool would look like, but the CSS-like language you see in UI frameworks like GTK is tailored for styling actual UI's.
In CSS on the web, just centering a div has historically been a problem. We have flexbox now, but what if CSS was designed with our current needs from the get-go?
compared to old css, it just keeps getting better
People keep reinventing 'better' styling tools, and we ends up with more bloat and more magic, while static UIs definately stay simpel.
