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 that can arrange child components in various ways. It's particularly useful for creating responsive layouts and organizing components in rows or columns.

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

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",
})

[!note] Overriding behavior Components inside Flex get an additional CSS class flex-component that add the display: flex property. If you want to override this behavior, you can add a display property to the component's CSS class in your custom CSS file.

.flex-component {
  display: block; // or any other display type
}

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

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

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.

type ConditionalRenderConfig = {
  component: QuartzComponent
  condition: (props: QuartzComponentProps) => boolean
}

Example Usage

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.

Component.ConditionalRender({
  component: Component.Breadcrumbs(),
  condition: (page) => page.fileData.slug !== "index",
})

The example above would hide breadcrumbs on the root index.md page.
