通常，页面会继承其上方的每个布局，这意味着 src/routes/a/b/c/+page.svelte 继承了四个布局：

¥Ordinarily, a page inherits every layout above it, meaning that src/routes/a/b/c/+page.svelte inherits four layouts:

• src/routes/+layout.svelte

• src/routes/a/+layout.svelte

• src/routes/a/b/+layout.svelte

• src/routes/a/b/c/+layout.svelte

有时，打破当前布局层次结构很有用。我们可以通过将 @ 符号后跟父段的名称添加到 ‘reset’ 来实现这一点 — 例如，+page@b.svelte 会将 /a/b/c 放在 src/routes/a/b/+layout.svelte 内，而 +page@a.svelte 会将其放在 src/routes/a/+layout.svelte 内。

¥Occasionally, it’s useful to break out of the current layout hierarchy. We can do that by adding the @ sign followed by the name of the parent segment to ‘reset’ to — for example +page@b.svelte would put /a/b/c inside src/routes/a/b/+layout.svelte, while +page@a.svelte would put it inside src/routes/a/+layout.svelte.

让我们将其重置为根布局，将其重命名为 +page@.svelte。

¥Let’s reset it all the way to the root layout, by renaming it to +page@.svelte.

根布局适用于应用的每个页面，你无法脱离它。
