👉 NOTE: Please resize your browser to mobile width (less than 768px) to see the toggle.
👉 注意:请将浏览器缩放至移动端宽度(小于 768px)以查看效果。

English: SEO & Logic

Crawlable: Because we don't use display: none on the menu for crawlers (we move it off-screen), search engines like Baidu can follow these links easily.

Zero-JS Resilience: If a user is on a slow connection and the JS fails to load, the site remains usable. This is "Progressive Enhancement."

中文:SEO 与逻辑

可抓取性: 我们不通过 display: none 隐藏菜单(而是将其移出屏幕外),百度等搜索引擎可以轻松抓取这些链接。

无 JS 韧性: 如果用户连接较慢导致 JS 加载失败,网站依然可用。这就是“渐进增强”的理念。

SEO Insight / SEO 优化见解

Mobile-First Indexing

Google and Baidu prioritize the mobile version of your site. If your mobile menu requires heavy JS to function, crawlers might see a "broken" navigation if scripts fail to execute. This CSS-only burger menu ensures your navigation is robust and indexable even in low-bandwidth scenarios.

谷歌和百度优先索引网站的移动版本。如果您的移动端菜单需要沉重的 JS 才能运行,一旦脚本执行失败,爬虫可能会看到一个“断裂”的导航。这种纯 CSS 汉堡菜单确保您的导航在低带宽场景下依然稳健且可索引。

Checkbox Hack for Lean Code

By using the :checked pseudo-class, we eliminate the need for "Event Listeners." This keeps the "Code-to-Content" ratio lean. The less time a bot spends parsing script logic, the more time it spends indexing your actual content.

通过使用 :checked 伪类,我们消除了对“事件监听器”的需求。这保持了精简的“代码内容比”。机器人花在解析脚本逻辑上的时间越少,花在索引您实际内容上的时间就越多。
