+title: Usage
+---
+
+# {{$frontmatter.title}}
+
+The standard behavior of `vue-semantic-structure` defines the most common approach for the use of HTML structure components.
+
+In this structure, the main content contains different modules *(example: Stage (Hero), Text-Image, Gallery, etc.)*.
+
+The main structure is in the `<main>` tag, which contains the main components.
+
+::: code-group
+
+```html [HTML]
+<main>
+  <header class="hero">…</header>
+  <section class="text-image">…</section>
+  <section class="gallery">…</section>
+</main>
+```
+
+```vue [Vue]
+<template>
+  <ContentContainer>
+    <header class="hero">…</header>
+    <ContentContainer class="text-image">…</ContentContainer>
+    <ContentContainer class="gallery">…</ContentContainer>
+  </ContentContainer>
+</template>
+```
+
+:::
+
+## Advance Usage
+
+The behavior of the `ContentContainer` can also be adapted for blog article pages.
+
+Here, an `<article>` is often used in the `<main>` tag, for which the `ContentContainer` must be adapted.
+
+The `rootTags` property must be extended by an `<article>` (e.g. `['main', 'article']`).
+
+It is recommended to create a separate component that extends the `ContentContainer`.
+
+### `CustomContentContainer.vue`
+
+```vue
+<template>
+  <ContentContainer :root-tags="['main', 'article']">
+    <slot />
+  </ContentContainer>
+</template>
+
+<script setup>
+import { ContentContainer } from 'vue-semantic-structure';
+</script>
+```
+
+In comparison to the basic application, the entire content is enclosed in another `CustomContentContainer` (e.g. `ContentContainer`), which represents the `<article>` tag.
+
+::: code-group
+
+```html [HTML]
+<main>
+  <article>
+    <header class="hero">…</header>
+    <section class="text-image">…</section>
+    <section class="gallery">…</section>
+  </article>
+</main>
+```
+
+```vue [Vue]
+<template>
+  <CustomContentContainer>
+    <CustomContentContainer>
+      <header class="hero">…</header>
+      <CustomContentContainer class="text-image">…</CustomContentContainer>
+      <CustomContentContainer class="gallery">…</CustomContentContainer>
+    </CustomContentContainer>
+  </CustomContentContainer>
+</template>
+```
