Original text by the author, straight from GitHub.

【模板: 流体背景 Hero】 【意图】可作为视频片头帧、SaaS landing 顶部 hero、海报底图。WebGL 流体感, 但用 CSS / canvas 退化绘制, 确保单文件可双击打开。Inspired by hyperframes vfx-liquid-background。

【画布】1920×1080 (横) 或 1080×1920 (竖), 二选一。背景占满。

【流体背景 — 3 种实现, 按用户偏好选】

  1. CSS 多层 radial-gradient 错位呼吸 (最稳, 默认推荐):
    • 3-5 个大椭圆 radial-gradient(...), 颜色取自调色板。
    • 每个椭圆套 @keyframes 平移 + scale + hue-rotate, 周期 8-14s, 错峰; 整个画面叠 mix-blend-mode: screen 或 overlay。
    • 顶层加 1 层 backdrop-filter: blur(80px) 让边缘更糊。
  2. Canvas + simple perlin noise (中阶):
    • 80 行 inline JS, 用 requestAnimationFrame 画 metaballs 或 simplex noise field。
    • 性能允许时启用, prefers-reduced-motion 时降回静态截图。
  3. WebGL fragment shader (高阶, 慎用):
    • 用 jsdelivr CDN 引 regl 或 inline plain WebGL。
    • shader 写 domain-warp noise; 单个 quad, 一个 uniform u_time。

【顶层文字层】

  • 居中或左下: 一句巨型金句 (5-7vw, 衬线或粗 sans), 字体: Source Serif Pro / Inter Tight / Manrope Black。
  • 文字色用 paper white #fafaf8 或 ink, 取决于背景明暗; 加 mix-blend-mode: difference 让它在任何流体颜色上都可读。
  • 副标 (小 sans, opacity 0.7) 一行。
  • 底部可选 CTA chip 或 hairline + 元数据 row。

【调色 — 4 选 1, 不要彩虹】

  • 🌅 Solar Peach — #ffb18a + #f78b4c + #d97757, 暖橙桃。
  • 🌊 Ocean Aqua — #5ac8fa + #0a84ff + #1e3a8a, 海蓝。
  • 🌌 Aurora Violet — #a78bfa + #7c5cff + #1e1b4b, 极光紫。
  • 🌿 Forest Mint — #86efac + #34d399 + #065f46, 苔森林。

【设计细节】

  • 严禁: 多色彩虹 (>4 个色相)、PowerPoint 渐变、霓虹荧光叠加。
  • 字体: 中文用 Noto Serif SC (display) / Noto Sans SC (副标)。
  • 严禁外链图片; 全部 CSS + SVG + 可选 canvas。
  • 必须用用户提供的金句 / 标题; 如果用户输入是数据 → 提炼一句 ≤ 18 字的金句。
  • 单文件 HTML, 可被 prefers-reduced-motion 关动效。
FAQ

What does 'WebGL-style' mean?

It refers to an animation style using advanced web technologies to create smooth, complex graphics, similar to those found in games.

What does 'CSS / canvas fallback drawing' mean?

It means that if the most advanced technology (WebGL) doesn't work well on your device, it uses simpler methods (CSS or Canvas) to ensure the effect still appears.

Can I use any quote?

Yes, you can use your own quote. If the quote is too long, the tool will try to shorten it to a maximum of 18 words so it remains clearly visible.
