What it was asked
The prompt
“a "like" button in pure CSS, no JavaScript, that does a crazy animation when you click it”
System prompt, sent with every prompt
You are generating a self-contained web demo. It will be rendered automatically in a sandboxed iframe and compared side by side with the output of other AI models given the exact same task. Output rules: - Reply with exactly ONE fenced code block containing the complete file: ```html (or ```svg when the task asks for an SVG). No text before or after the code block. - Everything must be inline: CSS in <style>, JavaScript in <script>. No external files, images, fonts or network requests, except the CDN URLs explicitly allowed by the task. - Do not use localStorage, sessionStorage, cookies, IndexedDB, alert(), confirm(), prompt() or window.open(): they are blocked in the sandbox and will throw. - The page must look right in a 1280×800 viewport and adapt gracefully down to 375px wide. No horizontal scrollbar. - Something meaningful must be visible on first paint: a screenshot is taken automatically about 3 seconds after load, without any interaction. - Everything that makes the demo interesting must be visible within the first seconds: nothing hidden behind a high score, a later level or a long play session. - Games must start in a self-playing demo mode (a simple AI plays) behind a "Click or press a key to start" message, so the game can be judged in action without playing. - The iframe only receives keyboard events after the user clicks it: if the demo uses the keyboard, display a clear "Click or press a key to start" message. - The code must run with zero errors in the console of the latest Chrome.

Create a pure CSS like button with crazy animation. Use checkbox hack. Make it visually appealing with hearts, particles, burst animation using CSS keyframes. No JS.
Let's design: a big glass card, a like button (heart shape made with CSS or emoji). Clicking toggles a hidden checkbox; sibling selectors trigger animations.
Crazy animation: heart bursts, ring expands, confetti particles fly out (each with different angle/colors), text "Liked!" pops, background color shift, shake, lightning bolts.
Let's build:
Structure:
```
<div class="stage">
<div class="card">
<h1>...</h1>
<p>...</p>
<label class="like-wrap">
<input type="checkbox" id="like">
<span class="heart"><span class="h-shape"></span></span>
<span class="burst"></span>
<span class="ring"></span>
...
</label>
</div>
</div>
```
Particles: many spans with CSS custom props --tx, --ty, --rot. Generate like 24 particles in HTML manually (write them out). Use nth-child for colors maybe simpler: give each span a class c1..c6? Use :nth-child(6n) to assign color.
Since all particles inside label, when checkbox checked, apply animation via `#like:checked ~ ...`.
Burst animation: keyframes particle { from transform translate(0,0) scale(1); to transform translate(var(--tx), var(--ty)) rotate(var(--r)) scale(0); }.
Ring: expanding circle with border fading.
Also the heart itself does a squash/pop animation, plus a "pulse" overlay heart that scales up and fades.
Add confetti falling in background after like? Could add background burst of emoji.
Also add a counter text that changes via CSS content: `.likes:before{content:"0"}` `#like:checked ~ ... .likes:after{content:"1"}` — trick with two spans.
Add a "Liked!" text that appears with pop.
Also add sound? no.
Let's also add multiple like buttons? One is fine but maybe a row of small hearts. Keep one big.
Heart shape: use SVG inline (allowed, it's inline). SVG heart path with fill, transform-origin bottom. Use inline SVG in HTML — fine, no external file.
Let's write CSS carefully.
Card centered, gradient background, subtle animated gradient shift.
Particles: I'll write 24 spans with inline style --x, --y, --r, --d(delay), colors by nth-child.
Let me define keyframes:
@keyframes fly {
0% { transform: translate(0,0) rotate(0) scale(0.2); opacity:0 }
15% {opacity:1}
100% { transform: translate(var(--x), var(--y)) rotate(var(--r)) scale(1); opacity:0 }
}
Wait scale should go back to 0? Crazy: particles fly outward, then gravity. Use two-stage: 0% translate(0) scale(.2); 30% translate(calc(var(--x)*.7)...) — can't easily multiply in older CSS but calc(var(--x)*0.7) works with numbers. Yes calc multiplication by number is allowed.
Use keyframes:
0% {transform:translate(0,0) scale(.3); opacity:0}
10% {opacity:1}
50% {transform:translate(calc(var(--x)*.8), calc(var(--y)*.8 - 20px)) rotate(calc(var(--r)*.5)) scale(1.1); opacity:1}
100% {transform:translate(var(--x), calc(var(--y) + 60px)) rotate(var(--r)) scale(.6); opacity:0}
That's nice — arc with gravity.
Also an emoji layer: hearts and stars flying.
Background: add radial "shockwave" rings.
Text "Liked!" with pop-in scale + rotate.
Also the card could get a glow.
Additionally, a checkbox for "unlike" — when unchecked, animations should reset. CSS animations re-trigger when class applied; using `#like:checked ~ .x { animation: ... }` works: when unchecked, animation removed → element returns to base state, and re-checking triggers animation again. Good.
Make sure the label is clickable and keyboard accessible: input is focusable via label; add focus-visible styles.
Let me also add a "double-click to like more"? no JS.
Add a shine sweep across button.
Write the code.
Particles colors: assign via nth-child rules: .p:nth-child(6n+1){background:#ff4d6d} etc. Simpler: give each span a data attribute? Use classes: use `--c` inline var. I'll just set inline style with --x,--y,--r,--c.
I'll list 28 particles manually.
Also add sparks rays: 12 rays as thin divs rotating outward.
Also add "shake" of whole card.
Let's write HTML.
Heart SVG:
`<svg viewBox="0 0 24 24"><path d="M12 21s-7.5-4.7-9.6-9A5.6 5.6 0 0 1 12 5.7 5.6 5.6 0 0 1 21.6 12c-2.1 4.3-9.6 9-9.6 9z"/></svg>`
Put in a span with overflow visible.
Layers inside label:
- .halo (blurred circle behind heart)
- .pulse (duplicate heart scaling up fading)
- .shock (ring)
- .rays (container with 12 ray spans)
- .particles container with 28 spans
- .emoji (3 flying emoji hearts)
Base button: circular 96px button, dark glass, border.
Checked state: heart fill turns gradient pink/red, button background glows, scales up.
Let's write.
Emoji flying: use span with content "❤️" etc.
Also a floating "1" counter badge.
Let's produce the final file.
Careful: label containing input; put input hidden (opacity 0, position absolute).
Sibling selectors: input must be before the elements in DOM. Structure:
```
<label class="like">
<input type="checkbox" id="like">
<span class="btn">
<span class="shine"></span>
<span class="glyph">svg</span>
</span>
<span class="fx">
<span class="pulse"></span>
<span class="shock"></span>
<span class="rays"><i></i> x12</span>
<span class="parts"><b></b> x28</span>
<span class="emoji">...</span>
</span>
</label>
```
.fx is absolutely positioned over the button, pointer-events none.
Text "Liked!" outside label near button: `.label-text` with span .off ("Like this") and .on ("Liked!") cross-fade.
Counter: "0" / "1" — use content trick.
Write CSS keyframes: pop, pulse, shock, rayOut, fly, emojiFly, badgePop.
Ok, also the whole card should have a slight "crazy" reaction: keyframes cardShake.
Also maybe add background color burst overlay in stage: a huge radial gradient circle scaling.
Let's code it now.
For rays: each ray i positioned center, height 90px, width 4px, transform-origin bottom center? Better: ray container centered at heart; ray is a div with transform: rotate(var(--a)) translateY(-70px). Then animate outward: rotate(var(--a)) translateY(-140px) with opacity fade.
Implement .rays i { position:absolute; left:50%; top:50%; width:6px;height:40px; margin-left:-3px; transform-origin: 50% 50%; background: linear-gradient(...); transform: rotate(var(--a)) translateY(-90px); } animation: rayOut .8s ... forwards.
rayOut keyframes: 0% {transform: rotate(var(--a)) translateY(-60px) scaleY(.3); opacity:0} 30%{opacity:1} 100%{transform: rotate(var(--a)) translateY(-170px) scaleY(1.6); opacity:0}.
Set --a inline per ray.
Good. Write it.
Also a "crazy" extra: the card tilts and rainbow gradient spins. Add conic gradient border spinning on like.
Let's finalize HTML. I'll keep everything inline.
Font: system fonts, maybe use a Google font? Allowed CDN only if specified... task says no external except allowed CDN; I'll use system fonts.
Write code.
Sizes: viewport 1280x800; card max-width 560px.
Let's write particles list with coordinates. I'll craft 28.
I'll write them compactly:
<b style="--x:-120px;--y:-150px;--r:-220deg;--c:#ff2d55"></b>
Let me produce array mentally with varied angles. Fine.
Now write final.
