What it was asked

The prompt

Create a set of four animated weather cards (sunny, rainy, snowy, stormy), made with HTML and CSS only. Requirements: - Absolutely no JavaScript: the file must not contain any <script> tag or inline event handler. - No images, no SVG, no icon fonts: every weather icon is built from HTML elements and pseudo-elements styled with CSS. - Each card shows an animated icon (rotating sun rays, falling rain drops, drifting snowflakes, flashing lightning), a city name, a temperature and a short description. - Each card has its own background gradient matching the weather. - The cards are displayed in a responsive grid (4 per row on desktop, stacked on mobile) and lift up on hover. - Smooth infinite animations using @keyframes, and respect prefers-reduced-motion.

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.
