+title: Reader Mode
+tags:
+  - component
+---
+
+Reader Mode is a feature that allows users to focus on the content by hiding the sidebars and other UI elements. When enabled, it provides a clean, distraction-free reading experience.
+
+## Configuration
+
+Reader Mode is enabled by default. To disable it, you can remove the component from your layout configuration in `quartz.layout.ts`:
+
+```ts
+// Remove or comment out this line
+Component.ReaderMode(),
+```
+
+## Usage
+
+The Reader Mode toggle appears as a button with a book icon. When clicked:
+
+- Sidebars are hidden
+- Hovering over the content area reveals the sidebars temporarily
+
+Unlike Dark Mode, Reader Mode state is not persisted between page reloads but is maintained during SPA navigation within the site.
+
+## Customization
+
+You can customize the appearance of Reader Mode through CSS variables and styles. The component uses the following classes:
+
+- `.readermode`: The toggle button
+- `.readerIcon`: The book icon
+- `[reader-mode="on"]`: Applied to the root element when Reader Mode is active
+
+Example customization in your custom CSS:
+
+```scss
+.readermode {
+  // Customize the button
+  svg {
+    stroke: var(--custom-color);
+  }
+}
+```
