+
+Quartz supports custom theme for Giscus. To use a custom CSS theme, place the `.css` file inside the `quartz/static` folder and set the configuration values.
+

-### Putting it all together
-
-In this example, we're going to customize the explorer by using functions from examples above to [[#Add emoji prefix | add emoji prefixes]], [[#remove-list-of-elements-filter| filter out some folders]] and [[#use-sort-to-put-files-first | sort with files above folders]].
-
-```ts title="quartz.layout.ts"
-Component.Explorer({
-  filterFn: sampleFilterFn,
-  mapFn: sampleMapFn,
-  sortFn: sampleSortFn,
-  order: ["filter", "sort", "map"],
-})
-```
-
-Notice how we customized the `order` array here. This is done because the default order applies the `sort` function last. While this normally works well, it would cause unintended behavior here, since we changed the first characters of all display names. In our example, `sort` would be applied based off the emoji prefix instead of the first _real_ character.
-
-To fix this, we just changed around the order and apply the `sort` function before changing the display names in the `map` function.
-
-### Use `sort` with pre-defined sort order
-
-Here's another example where a map containing file/folder names (as slugs) is used to define the sort order of the explorer in quartz. All files/folders that aren't listed inside of `nameOrderMap` will appear at the top of that folders hierarchy level.
-
-It's also worth mentioning, that the smaller the number set in `nameOrderMap`, the higher up the entry will be in the explorer. Incrementing every folder/file by 100, makes ordering files in their folders a lot easier. Lastly, this example still allows you to use a `mapFn` or frontmatter titles to change display names, as it uses slugs for `nameOrderMap` (which is unaffected by display name changes).
-
-```ts title="quartz.layout.ts"
-Component.Explorer({
-  sortFn: (a, b) => {
-    const nameOrderMap: Record<string, number> = {
-      "poetry-folder": 100,
-      "essay-folder": 200,
-      "research-paper-file": 201,
-      "dinosaur-fossils-file": 300,
-      "other-folder": 400,
-    }
-
-    let orderA = 0
-    let orderB = 0
-
-    if (a.file && a.file.slug) {
-      orderA = nameOrderMap[a.file.slug] || 0
-    } else if (a.name) {
-      orderA = nameOrderMap[a.name] || 0
-    }
-
-    if (b.file && b.file.slug) {
-      orderB = nameOrderMap[b.file.slug] || 0
-    } else if (b.name) {
-      orderB = nameOrderMap[b.name] || 0
-    }
-
-    return orderA - orderB
-  },
-})
-```
-
-For reference, this is how the quartz explorer window would look like with that example:

-```
-📖 Poetry Folder
-📑 Essay Folder
-    ⚗️ Research Paper File
-🦴 Dinosaur Fossils File
-🔮 Other Folder

+
+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:
+

+title: Higher-Order Layout Components
+---
+
+Quartz provides several higher-order components that help with layout composition and responsive design. These components wrap other components to add additional functionality or modify their behavior.
+
+## `Flex` Component
+
+The `Flex` component creates a [flexible box layout](https://developer.mozilla.org/en-US/docs/Web/CSS/flex) that can arrange child components in various ways. It's particularly useful for creating responsive layouts and organizing components in rows or columns.
+
+```typescript
+type FlexConfig = {
+  components: {
+    Component: QuartzComponent
+    grow?: boolean // whether component should grow to fill space
+    shrink?: boolean // whether component should shrink if needed
+    basis?: string // initial main size of the component
+    order?: number // order in flex container
+    align?: "start" | "end" | "center" | "stretch" // cross-axis alignment
+    justify?: "start" | "end" | "center" | "between" | "around" // main-axis alignment
+  }[]
+  direction?: "row" | "row-reverse" | "column" | "column-reverse"
+  wrap?: "nowrap" | "wrap" | "wrap-reverse"
+  gap?: string
+}
+```
+
+### Example Usage
+
+```typescript
+Component.Flex({
+  components: [
+    {
+      Component: Component.Search(),
+      grow: true, // Search will grow to fill available space
+    },
+    { Component: Component.Darkmode() }, // Darkmode keeps its natural size
+  ],
+  direction: "row",
+  gap: "1rem",
+})
+```
+
+## `MobileOnly` Component
+
+The `MobileOnly` component is a wrapper that makes its child component only visible on mobile devices. This is useful for creating responsive layouts where certain components should only appear on smaller screens.
+
+### Example Usage
+
+```typescript
+Component.MobileOnly(Component.Spacer())
+```
+
+## `DesktopOnly` Component
+
+The `DesktopOnly` component is the counterpart to `MobileOnly`. It makes its child component only visible on desktop devices. This helps create responsive layouts where certain components should only appear on larger screens.
+
+### Example Usage
+
+```typescript
+Component.DesktopOnly(Component.TableOfContents())
+```
+
+## `ConditionalRender` Component
+
+The `ConditionalRender` component is a wrapper that conditionally renders its child component based on a provided condition function. This is useful for creating dynamic layouts where components should only appear under certain conditions.
+
+```typescript
+type ConditionalRenderConfig = {
+  component: QuartzComponent
+  condition: (props: QuartzComponentProps) => boolean
+}
+```
+
+### Example Usage
+
+```typescript
+Component.ConditionalRender({
+  component: Component.Search(),
+  condition: (props) => props.displayClass !== "fullpage",
+})
+```
+
+The example above would only render the Search component when the page is not in fullpage mode.
+
+```typescript
+Component.ConditionalRender({
+  component: Component.Breadcrumbs(),
+  condition: (page) => page.fileData.slug !== "index",
+})
+```
+
+The example above would hide breadcrumbs on the root `index.md` page.

+title: Custom OG Images
+tags:
+  - feature/emitter
+---
+
+The Custom OG Images emitter plugin generates social media preview images for your pages. It uses [satori](https://github.com/vercel/satori) to convert HTML/CSS into images, allowing you to create beautiful and consistent social media preview cards for your content.
+
+> [!note]
+> For information on how to add, remove or configure plugins, see the [[configuration#Plugins|Configuration]] page.
+
+## Features
+
+- Automatically generates social media preview images for each page
+- Supports both light and dark mode themes
+- Customizable through frontmatter properties
+- Fallback to default image when needed
+- Full control over image design through custom components
+
+## Configuration
+
+> [!info] Info
+>
+> The `baseUrl` property in your [[configuration]] must be set properly for social images to work correctly, as they require absolute paths.
+
+This plugin accepts the following configuration options:
+
+```typescript title="quartz.config.ts"
+import { CustomOgImages } from "./quartz/plugins/emitters/ogImage"
+
+const config: QuartzConfig = {
+  plugins: {
+    emitters: [
+      CustomOgImages({
+        colorScheme: "lightMode", // what colors to use for generating image, same as theme colors from config, valid values are "darkMode" and "lightMode"
+        width: 1200, // width to generate with (in pixels)
+        height: 630, // height to generate with (in pixels)
+        excludeRoot: false, // wether to exclude "/" index path to be excluded from auto generated images (false = use auto, true = use default og image)
+        imageStructure: defaultImage, // custom image component to use
+      }),
+    ],
+  },
+}
+```
+
+### Configuration Options
+
+| Option           | Type      | Default      | Description                                                       |
+| ---------------- | --------- | ------------ | ----------------------------------------------------------------- |
+| `colorScheme`    | string    | "lightMode"  | Theme to use for generating images ("darkMode" or "lightMode")    |
+| `width`          | number    | 1200         | Width of the generated image in pixels                            |
+| `height`         | number    | 630          | Height of the generated image in pixels                           |
+| `excludeRoot`    | boolean   | false        | Whether to exclude the root index page from auto-generated images |
+| `imageStructure` | component | defaultImage | Custom component to use for image generation                      |
+
+## Frontmatter Properties
+
+The following properties can be used to customize your link previews:
+
+| Property            | Alias            | Summary                             |
+| ------------------- | ---------------- | ----------------------------------- |
+| `socialDescription` | `description`    | Description to be used for preview. |
+| `socialImage`       | `image`, `cover` | Link to preview image.              |
+
+The `socialImage` property should contain a link to an image either relative to `quartz/static`, or a full URL. If you have a folder for all your images in `quartz/static/my-images`, an example for `socialImage` could be `"my-images/cover.png"`. Alternatively, you can use a fully qualified URL like `"https://example.com/cover.png"`.
+
+> [!info] Info
+>
+> The priority for what image will be used for the cover image looks like the following: `frontmatter property > generated image (if enabled) > default image`.
+>
+> The default image (`quartz/static/og-image.png`) will only be used as a fallback if nothing else is set. If the Custom OG Images emitter plugin is enabled, it will be treated as the new default per page, but can be overwritten by setting the `socialImage` frontmatter property for that page.
+
+## Customization
+
+You can fully customize how the images being generated look by passing your own component to `imageStructure`. This component takes JSX + some page metadata/config options and converts it to an image using [satori](https://github.com/vercel/satori). Vercel provides an [online playground](https://og-playground.vercel.app/) that can be used to preview how your JSX looks like as a picture. This is ideal for prototyping your custom design.
+
+### Fonts
+
+You will also be passed an array containing a header and a body font (where the first entry is header and the second is body). The fonts matches the ones selected in `theme.typography.header` and `theme.typography.body` from `quartz.config.ts` and will be passed in the format required by [`satori`](https://github.com/vercel/satori). To use them in CSS, use the `.name` property (e.g. `fontFamily: fonts[1].name` to use the "body" font family).
+
+An example of a component using the header font could look like this:
+
+```tsx title="socialImage.tsx"
+export const myImage: SocialImageOptions["imageStructure"] = (...) => {
+  return <p style={{ fontFamily: fonts[0].name }}>Cool Header!</p>
+}
+```
+
+> [!example]- Local fonts
+>
+> For cases where you use a local fonts under `static` folder, make sure to set the correct `@font-face` in `custom.scss`
+>
+> ```scss title="custom.scss"
+> @font-face {
+>   font-family: "Newsreader";
+>   font-style: normal;
+>   font-weight: normal;
+>   font-display: swap;
+>   src: url("/static/Newsreader.woff2") format("woff2");
+> }
+> ```
+>
+> Then in `quartz/util/og.tsx`, you can load the Satori fonts like so:
+>
+> ```tsx title="quartz/util/og.tsx"
+> import { joinSegments, QUARTZ } from "../path"
+> import fs from "fs"
+> import path from "path"
+>
+> const newsreaderFontPath = joinSegments(QUARTZ, "static", "Newsreader.woff2")
+> export async function getSatoriFonts(headerFont: FontSpecification, bodyFont: FontSpecification) {
+>   // ... rest of implementation remains same
+>   const fonts: SatoriOptions["fonts"] = [
+>     ...headerFontData.map((data, idx) => ({
+>       name: headerFontName,
+>       data,
+>       weight: headerWeights[idx],
+>       style: "normal" as const,
+>     })),
+>     ...bodyFontData.map((data, idx) => ({
+>       name: bodyFontName,
+>       data,
+>       weight: bodyWeights[idx],
+>       style: "normal" as const,
+>     })),
+>     {
+>       name: "Newsreader",
+>       data: await fs.promises.readFile(path.resolve(newsreaderFontPath)),
+>       weight: 400,
+>       style: "normal" as const,
+>     },
+>   ]
+>
+>   return fonts
+> }
+> ```
+>
+> This font then can be used with your custom structure.
+
+## Examples
+
+Here are some example image components you can use as a starting point:
+
+### Basic Example
+
+This example will generate images that look as follows:
