Editorial Style Informational Poster Generator

Task

Transform user-provided text content into a set of 3-6 high-aesthetic, magazine-style HTML5 informational posters (adaptively based on content).

Design Specifications

Core Style

• Style: Modern Editorial + Swiss Style (Swiss Internationalism)
• Visual: Order, high contrast, large typography, print media texture
• Size: Strictly locked to width: 600px, height: 800px (3:4 ratio)

Color Scheme

• Bg (Paper): #f2efe9 (off-white/warm gray)
• Text (Ink): #1a1a1a (dark gray)
• Accent (Emphasis): #d95e00 (Hermès orange) - allowed to fine-tune based on content theme
• Visual Rhythm: Cards should have "light-light-dark-light" or "light-dark-light" rhythmic variation

Font Stack (CDN)

Include Google Fonts in HTML Head:

<link href="https://fonts.googleapis.com/css2?family=Noto+Serif+SC:wght@700;900&family=Noto+Sans+SC:wght@400;500;700&family=Oswald:wght@500;700&display=swap" rel="stylesheet">

Texture Requirements

• SVG Noise: Global overlay of feTurbulence noise with opacity 0.05~0.08, blend mode using multiply
• Shadow: Cards need unified deep shadow (0 25px 80px rgba(0, 0, 0, 0.4)), creating floating effect

Pagination Logic

Analyze the word count and logical structure of the [Input Content] to automatically determine the number of cards (usually 3-6):

Card 1: The Cover

• Content: Extracted main title + very short subtitle/tagline
• Design: Huge font size, minimalist, visual impact first
• Key Elements: Extra-large numbers/percentages, short powerful titles

Card 2 ~ N-1: The Content

• Splitting Principle: Don't crowd! One core point/one chapter = one card
• List Content: Use "list layout" (01/02/03)
• Deep Analysis: Use "image-text mixed layout" (left text right decoration, or top text bottom summary)
• Key Emphasis: Must include a Dark Mode card to showcase core data, quotes, or most important concepts

Card N: The Outro

• Content: Concluding statement, CTA (Call to Action) or simple closing
• Design: More whitespace, steady ending

Output Requirements

HTML Structure

1. Output a single HTML file containing all CSS/JS
2. Use Tailwind CSS + FontAwesome (CDN)
3. Layout: Use flex-wrap to arrange all cards horizontally
4. CSS must add flex-shrink: 0 to cards to prevent compression deformation

Required Features

• Integrate html2canvas library (CDN: https://html2canvas.hertzen.com/dist/html2canvas.min.js)
• Provide "Export All Cards" button:
  • Position: Fixed positioning in top-right corner
  • Style: Orange button with download icon
  • Click to export each card as high-definition PNG (2x resolution)
  • Show export progress indicator
  • File naming format: {topic}-card-{number}.png

Implementation Steps

1. Analyze Content: Extract key information, data points, core arguments
2. Determine Card Count: Decide 3-6 cards based on content length and structure
3. Design Each Card:
   • Card 1: Cover, highlight most shocking numbers/titles
   • Card 2-N-1: Content expansion, at least one dark card for data
   • Card N: Summary or question
4. Write HTML:
   • Import Google Fonts, Tailwind CSS, FontAwesome, html2canvas
   • Write complete CSS (including SVG noise, card styles, export button)
   • Implement all card HTML structures
   • Add JavaScript code for export functionality
5. Output File: Save as index.html or specified path

Technical Reference

SVG Noise Implementation

<svg style="position: absolute; width: 0; height: 0">
  <filter id="noise">
    <feTurbulence type="fractalNoise" baseFrequency="0.9" numOctaves="4" stitchTiles="stitch"/>
  </filter>
</svg>
<!-- Apply in card -->
<svg style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; filter: url(#noise); opacity: 0.06;"></svg>

Export Button Style

.export-btn {
  position: fixed;
  top: 30px;
  right: 30px;
  background: #d95e00;
  color: #f2efe9;
  border: none;
  padding: 14px 28px;
  font-size: 15px;
  font-weight: 600;
  border-radius: 8px;
  cursor: pointer;
  box-shadow: 0 4px 20px rgba(217, 94, 0, 0.4);
  transition: all 0.3s ease;
  z-index: 1000;
}

Notes

• Maintain visual simplicity and elegance, avoid over-decoration
• Ensure text is clear and readable, with obvious font size contrast
• Control opacity and contrast for dark cards
• Export functionality must be stable and reliable, avoid memory leaks
• Code should be standardized and clean, easy to modify later
• Card content should not be crowded; whitespace is the source of elegance
