这段代码实现了一个带有动态光效的Logo展示效果。以下是代码的主要功能和优化建议： 1. CSS变量：使用了CSS变量（`--deep-blue`、`--mid-blue`、`--light-blue`、`--accent`）来定义颜色，便于统一管理和修改。 2. 渐变：`.logo-container`使用了线性渐变，从深蓝到中蓝，营造出层次感。 3. 光效动画：`.glow-ring`使用了径向渐变和模糊效果，结合`pulse`动画，实现了光圈的动态缩放和透明度变化。 4. 文字效果：`.letter`使用了字体阴影和伪元素（`::after`）实现了文字的渐变边框效果。 优化建议： 1. 动画性能：`pulse`动画中使用了`transform: scale`和`opacity`，这些属性对性能影响较小，但可以进一步优化动画的流畅性，例如减少`filter: blur`的使用频率。 2. 字体加载：`Montserrat`字体通过Google Fonts加载，建议在`<head>`中添加`<link rel="preconnect" href="https://fonts.gstatic.com">`以加速字体加载。 3. 响应式设计：`.logo-container`的宽度和高度是固定的，建议使用相对单位（如`vw`、`vh`）或媒体查询来实现响应式设计。 额外需要注意的逻辑点： 1. 浏览器兼容性：`filter: blur`和CSS变量在某些旧版浏览器中可能不支持，建议添加备用方案或使用Polyfill。 2. 动画性能测试：在高性能要求的场景下，建议测试`pulse`动画的性能，确保不会导致页面卡顿。 3. 字体加载失败处理：如果Google Fonts加载失败，页面会回退到默认字体，建议在CSS中定义备用字体栈。 如果需要进一步优化或有其他问题，请随时告知！ [2025-03-22 09:37:27 | AI写代码神器 | 416点数解答]
