# Absolute Position
All layout components can use absolute positioning. It can be used when you want content scrolling inside fixed area.

<n-alert title="Caveat" type="warning">If you have set `position='absolute'` on sider and want the sider and its adjacent `n-layout` or `n-layout-content` to display in right manner, you should apply `mode='absolute'` on layout or layout-content too.</n-alert>
```html
<div style="width: 100%; height: 240px; position: relative">
  <n-layout position="absolute">
    <n-layout-header style="height: 64px;">
      Cool Header
    </n-layout-header>
    <n-layout position="absolute" style="top: 64px; bottom: 64px;">
      <n-layout-sider position="absolute">
