Horse Sticker Maker

Create and deploy a festive Chinese New Year (Year of the Horse 2026) animated GIF sticker maker web app. Use when the user wants to generate custom horse-themed blessing stickers, deploy a sticker generator H5 page, or create WeChat-compatible animated GIF stickers with gold horse animation on red background. Supports custom text input, 6-frame gold horse galloping animation, Canvas-based client-side GIF rendering via gif.js, and Vercel deployment.

Generate a web app that creates custom animated GIF stickers for Chinese New Year (Year of the Horse 2026).

What It Does

• Users input custom blessing text (1-8 chars)
• Client-side Canvas renders a 240px animated GIF with:
  • Red gradient background with gold sparkle particles
  • 6-frame gold horse galloping animation (transparent PNG)
  • User's custom text in gold calligraphy at top
  • "立马加薪" bottom text with color-cycling effect
• Output is WeChat sticker compatible (≤500KB, 240px)
