src/routes/path/to/+layout.vueRoot Layout 
To enable the root layout, add a src/routes/+layout.vue file.
vue
<!-- src/routes/+layout.vue -->
<template>
  <div class="p-4">
    <RouterView />
  </div>
</template>Nesting Layouts 
Declare <RouterView /> in src/routes/users/[id]/+layout.vue:
vue
<template>
  <h2>User {{ $route.params.id }}</h2>
  <RouterView />
</template>coffee
src/routes/users/[id]/+layout.vue
src/routes/users/[id]/(home)/+page.vue -> /users/:id
src/routes/users/[id]/profile/+page.vue -> /users/:id/profile
src/routes/users/[id]/posts/+page.vue -> /users/:id/postsMultiple Root Layouts 
coffee
src/routes/+layout.vue
src/routes/(marketing)/+layout.vue
src/routes/(shop)/+layout.vueIn the example above, both (marketing) and (shop) have their own root layout.
