The examples below demonstrate that high-quality web design doesn't require high-weight dependencies. At Jademond Digital, we help our clients build leaner, SEO-friendly, and JS-independent websites that perform better for both humans and bots.
以下示例证明,高质量的网页设计不需要沉重的依赖项。在 Jademond,我们帮助客户构建更精简、 对 SEO 友好且不依赖 JS 的网站,让它们在用户和搜索引擎面前表现更佳。
Modern web development has a "bloat" problem. Too often, we see pages where 90% of the 900KB+ payload is heavy JavaScript. This is not just unnecessary—it is a significant barrier to organic search success.
Building with a CSS-First mindset ensures that your core content is always accessible to search engines like Baidu and users on restricted networks. JavaScript should be the "icing on the cake"—used to add smooth transitions, handle complex API data, or provide advanced state management that native HTML cannot achieve.
现代网页开发面临着“冗余”问题。我们经常看到一些页面,在 900KB 以上的总量中,90% 都是沉重的 JavaScript。 这不仅毫无必要,更是有机搜索排名的一大障碍。
以 CSS 优先的思维进行构建,可以确保您的核心内容始终能被百度等搜索引擎以及受限网络环境下的用户访问。 JavaScript 应该是“锦上添花”:用于添加平滑过渡、处理复杂的 API 数据,或提供原生 HTML 无法实现的进阶状态管理。
It is perfectly acceptable to use JS for functionalities like real-time data filtering, complex drag-and-drop interfaces, or 3D rendering. For the patterns shown above, JS can be added to enhance UX—for example, adding keyboard shortcuts or tracking analytics—without breaking the feature if the script fails to load.
对于实时数据过滤、复杂的拖放界面或 3D 渲染等功能,使用 JS 是完全合理的。对于上述模式, 可以添加 JS 来提升用户体验(例如添加快捷键或埋点统计),但即便脚本加载失败,功能本身也不应受损。
