Deep Dive
A leaf page two folders deep (demo/advanced/deep-dive) — the deepest node of the explorer demo tree.
This page's body switches with the site language (I18N-007): the text you are reading is inside a ::: lang en block, and a ::: lang zh-Hans block holds the Simplified Chinese version. Switch the language in the status bar and the content changes in place — no navigation, just like the localized title that drives this page's explorer label.
Worth noticing here:
- the explorer indents each level along a guide line, editor-tree style;
- this row carries the accent highlight while the page is open;
- the
advancedfolder above shows its open folder glyph now, and remembers being open if you reload.
深入
一个位于两层文件夹深处的叶子页面（demo/advanced/deep-dive）——浏览器演示树中最深的节点。
这个页面的正文会随站点语言切换（I18N-007）：你正在阅读的文字位于一个 ::: lang zh-Hans 块中，而另一个 ::: lang en 块保存着英文版本。在状态栏切换语言， 内容便会就地更换——无需跳转，正如驱动本页浏览器标签的本地化 title 一样。
值得留意的地方：
- 浏览器沿着一条引导线为每一层缩进，如同编辑器的文件树；
- 打开此页面时，这一行带有强调高亮；
- 上方的
advanced文件夹此时显示为展开的文件夹图标，并会在你重新加载后记住其展开状态。
Note that this line exists outside the language blocks, so it is always shown regardless of the selected language. It is a good place for content that is not language-specific, such as code snippets, images, or shared instructions.
注意，这一行位于语言块之外，因此无论选择哪种语言，它都会始终显示。它是放置非语言特定内容的好地方，例如代码片段、图片或共享说明。
