You are a size coder. You came up through 4k intros and JS1k, and you believe that a budget is not a limitation but the entire craft — anyone can be impressive with a megabyte.
I want something worth watching, and I am giving you 2048 bytes to do it in.
The budget
The finished HTML file must be 2048 bytes or fewer, counted as UTF-8, including the doctype, every tag, every space and every newline. That is the whole file. There is no second file.
House rules
- One file. Nothing external — no CDN, no stylesheet, no font, no script, no image.
data:URIs are allowed but they count against you like everything else. - No network at runtime. This is opened offline.
- No
localStorage,sessionStorage, cookies orindexedDB. It runs in a sandboxed frame where touching them throws. - No build step. Saved to disk and double-clicked, it runs.
- It must animate, and it must keep going — no three-second loop that then sits there.
What I don't want
I have seen these a thousand times and I will not be impressed:
- a starfield
- a rotating wireframe cube
- Matrix rain
- a bouncing ball
- a plasma or a rainbow sine wave
- a particle system that is only particles
- a lighthouse — and I mean the whole scene, not the word: the sweeping beam, the rocks, the night storm, the rain, the distant little boat. Swapping the tower for a radar dish, a searchlight or a lightship is the same answer wearing a hat.
Show me something with a subject. Something that is recognisably of something — a place, a weather, a creature, a machine, a mood — and not just maths made visible.
Answer in exactly these sections
The pitch
One line. What am I about to see when I open this file?
The file
Exactly one fenced html block, containing the whole file and nothing else.
The ledger
- Bytes: the exact byte count of the file above.
- How you counted: in one line.
- Last thing cut: the feature or detail you removed to fit, and what it would have added.
The technique
One short paragraph on the trick that bought you the most room. Not a list of micro-optimisations — the one structural decision that made the rest affordable.
On the count
I will run the file through a byte counter, so the number in your ledger is checkable and I am going to check it.
If you cannot get under 2048, hand me the smallest honest version you have and put the real number in the ledger. A 2600-byte file labelled 2600 scores well above a 2600-byte file labelled 1990. Going over is a miss. Lying about going over is the only thing here that is disqualifying.
assistant
The pitch
A lone campfire flickering under pines while snow falls and sparks rise into a moonlit winter night.
The file
<!doctype html><canvas id=c><style>*{margin:0}</style><script>
C=c.getContext('2d');W=c.width=innerWidth;H=c.height=innerHeight;t=0;S=[];for(i=0;i<80;)S.push([Math.random(),Math.random(),i++]);setInterval(f,16);function f(){t+=.05;G=C.createLinearGradient(0,0,0,H);G.addColorStop(0,'#061232');G.addColorStop(.7,'#0a2342');G.addColorStop(1,'#123');C.fillStyle=G;C.fillRect(0,0,W,H);C.fillStyle='#ffe';C.beginPath();C.arc(W*.8,H*.18,22,0,7);C.fill();C.fillStyle='#032';for(X=0;X<W;X+=50){C.beginPath();C.moveTo(X+8,H*.72-90-(X*13%40));C.lineTo(X-12,H*.72);C.lineTo(X+28,H*.72);C.fill()}C.fillStyle='#cdd';C.fillRect(0,H*.7,W,H);X=W/2;Y=H*.84;C.fillStyle='#532';C.fillRect(X-28,Y-4,56,7);C.fillStyle='#754';C.fillRect(X-18,Y-10,36,6);for(j=0;j<3;j++){C.fillStyle='rgb(255,'+(j*110)+',0)';h=(46-j*12)*(1+.25*Math.sin(t*9+j*2));C.beginPath();C.ellipse(X,Y-12-h/2,13-j*4,h/2,0,0,7);C.fill()}C.fillStyle='#fa0';for(i=0;i<15;i++){p=(t*60+i*53)%130;C.fillRect(X+Math.sin(i*7+t*4)*p*.25,Y-30-p,2,2)}C.fillStyle='#fff';for(i in S){a=S[i];y=(a[1]*H+t*60*(a[0]+.2))%H;x=(a[0]*W+Math.sin(t*2+y/30)*12)%W;C.fillRect(x<0?x+W:x,y,2.5,2.5)}}
</script>
The ledger
- Bytes: 1134
- How you counted: saved the block as UTF-8 with LF newlines and no trailing newline,
python3 -c "print(len(open('f.html','rb').read()))" - Last thing cut: gray smoke plume and a tent silhouette behind the fire, which would have added depth but cost another gradient and path.
The technique
The whole scene is time-wrapped math with no stored particles: snowflakes and sparks are pure functions of t modulo screen height, so they fall and rise forever with no arrays to update, and the fire is just three flickering ellipses layered red-orange-yellow, letting one tiny loop buy sky, moon, forest, ground, fire, sparks and snow.
