Frame Liquid Bg Hero
This generates a full-screen fluid background with a centered quote overlay, the kind you'd drop into a video intro or use as a hero section. It offers three implementation tiers: CSS radial gradients with animated blend modes (safest, default), canvas with perlin noise, or WebGL shaders if you want the real deal. Ships as a single HTML file with no external images. Comes with four locked color palettes (Solar Peach, Ocean Aqua, Aurora Violet, Forest Mint) to keep you from making a rainbow mess. Text uses difference blend mode so it stays readable against any shifting background color. Respects prefers-reduced-motion. It's basically a disciplined version of those hyperframes VFX templates, constrained enough that you won't spend an hour tweaking gradients.

【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】
- 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。
- 3-5 个大椭圆
- 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。
- 80 行 inline JS, 用
- 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。
- 用 jsdelivr CDN 引
【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。
