【模板: VFX 文字光标 (Text Cursor)】 【意图】视频开场/Hero 帧 —— 光标在画布上"打字", 文字逐字浮现, 后面拖着彩色像散尾迹 + 定向光斑。Inspired by hyperframes vfx-text-cursor。

【画布】1920×1080, 背景 #06070a 暗哑黑 或 #0a0d12 (有暖偏蓝); 加微妙 vignette。

【内容】

  • 一句金句 (中英不限), 居中, 字号 6-8vw, weight 700, 字体 Inter Tight / Source Sans 3 / Noto Sans SC。
  • 逐字揭示, 每个字符 80ms 间隔; 当前字符后面跟着一个 cursor ▍ (或细 vertical bar)。
  • 已揭示文字默认白色 #f5f5f7, opacity 1; 即将揭示位置加 chromatic ghost: 一份 text-shadow: 2px 0 #ff3b6f, -2px 0 #00d4ff 在 reveal 瞬间, 200ms 内收敛回正常。
  • 光标本身: 16px 宽矩形, 颜色 = accent (取 1: hot pink #ff3b6f / cyan #00d4ff / amber #ffb547), 闪烁 @keyframes 1.0s 周期; 后面拖一条 60-120px 的 motion blur trail (径向渐变到透明)。

【光斑 / 射线】

  • 在打字位置附近随机生成 3-5 道定向光斑 (light leak): 用 linear-gradient(45deg, transparent, accent20, transparent) 的细长矩形 + mix-blend-mode: screen, 不规则角度。
  • 当文字打完, 整段文字加 0.5s shimmer sweep (光带横扫)。

【字段】

  • 顶部 caption (uppercase letterspace 0.18em, 11px, opacity 0.5): "FRAME 01 · OPENING"。
  • 文字底下副标 (24-28px, opacity 0.6): 来源 / 章节。
  • 右下角 timecode (00:03:21 mono)。

【设计细节】

  • 绝不: 多色彩虹 chromatic (只用 1 个 hot pink + cyan 这种二元像散, 不要 R/G/B 全色)。
  • 字体: 西文 Inter Tight Bold; 中文 Noto Sans SC Bold; 严禁衬线。
  • 动效用 @keyframes + JS 计时器 (setTimeout 逐字), 可被 prefers-reduced-motion 关闭 (直接显示所有字)。
  • 必须用用户提供的金句; 不要捏造。
  • 单文件 HTML, 不要外链字体以外的资源。
