Generation process

Step 1: Design the copy

Extract from user input:

• Main title(largest text, 1 line, core concept/product name/keyword)
• Subtitle(second-largest text, 1-2 lines, core insight or tagline)
• Tags(3 feature/keyword tags, each 2-4 characters)
• Corner label(small text in the top-left, identity label such as OPEN SOURCE / paper interpretation / tool recommendation)
• Bottom(small text, 3 keywords separated by ·)

Step 2: Choose the style

• If the user specified --style, use the corresponding style
• Otherwise auto-select based on the content:
  • Paper/research → academic
  • AI/programming/open source → dark or morandi
  • Tools/productivity → mint
  • Personal reflections/launches → sunset
  • Opinions/thinking → bw

Step 3: Generate the HTML

Write to /tmp/xhs-cover.html, following the template structure below:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
  * { margin: 0; padding: 0; box-sizing: border-box; }
  body { width: 1080px; height: 1440px; overflow: hidden;
         font-family: -apple-system, "PingFang SC", "Helvetica Neue", sans-serif; }
  .canvas {
    width: 1080px; height: 1440px;
    background: {风格背景};
    display: flex; flex-direction: column; justify-content: center;
    padding: 60px 70px; gap: 36px; position: relative;
  }
  /* 角标 */
  .badge { display: inline-flex; align-items: center; gap: 10px;
           background: {主色 alpha 0.12}; border: 1.5px solid {主色 alpha 0.2};
           border-radius: 10px; padding: 12px 24px; font-size: 28px;
           font-weight: 700; color: {主色}; letter-spacing: 3px; width: fit-content; }
  /* 主标题行 */
  .title-row { display: flex; align-items: baseline; gap: 20px; white-space: nowrap; }
  .title-main { font-size: 120-130px; font-weight: 900; color: {主色}; letter-spacing: -2px; }
  .title-secondary { font-size: 110-120px; font-weight: 900; color: {副色}; }
  /* 分隔线 */
  .divider { width: 80px; height: 5px;
             background: linear-gradient(90deg, {主色}, {副色});
             border-radius: 3px; margin: 10px 0; }
  /* 副标题 */
  .tagline { font-size: 76-82px; font-weight: 800; color: {文字色};
             letter-spacing: 8px; line-height: 1.4; }
  .tagline .accent { color: {主色 或副色 淡化}; }
  /* 标签 */
  .chip { background: {标签背景}; border-radius: 14px; padding: 18px 32px;
          font-size: 34px; font-weight: 700; letter-spacing: 2px; }
  /* 底部 */
  .footer { font-size: 30px; color: {文字色 淡化}; font-weight: 600; letter-spacing: 2px; }
</style>
</head>
<body>
  <!-- 按上面的结构填充内容 -->
</body>
</html>

Key design constraints:

• 3:4 ratio (1080×1440px)
• Text occupies more than 70% of the canvas
• Keep the main title on one line if possible (reduce font size or split lines if necessary)
• 2-3 levels of text hierarchy: main title > subtitle > tags/bottom
• Use font-weight: 700-900 for all Chinese text
• Use at most 3 colors (primary + secondary + accent), not cluttered

Step 4: Screenshot

Take and save a screenshot with Playwright:

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page(viewport={"width": 1080, "height": 1440})
    page.goto("file:///tmp/xhs-cover.html")
    page.wait_for_timeout(500)
    page.screenshot(path="<输出路径>", full_page=False)
    browser.close()
