title: Layout

Certain emitters may also output [HTML](https://developer.mozilla.org/en-US/docs/Web/HTML) files. To enable easy customization, these emitters allow you to fully rearrange the layout of the page. The default page layouts can be found in `quartz.layout.ts`.

Each page is composed of multiple different sections which contain `QuartzComponents`. The following code snippet lists all of the valid sections that you can add components to:

```typescript title="quartz/cfg.ts"
export interface FullPageLayout {
  head: QuartzComponent // single component
  header: QuartzComponent[] // laid out horizontally
  beforeBody: QuartzComponent[] // laid out vertically
  pageBody: QuartzComponent // single component
  afterBody: QuartzComponent[] // laid out vertically
  left: QuartzComponent[] // vertical on desktop, horizontal on mobile
  right: QuartzComponent[] // vertical on desktop, horizontal on mobile
  footer: QuartzComponent // single component
}
```

These correspond to following parts of the page:

> [!note]
> There are two additional layout fields that are _not_ shown in the above diagram.
>
> 1. `head` is a single component that renders the `<head>` [tag](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/head) in the HTML. This doesn't appear visually on the page and is only is responsible for metadata about the document like the tab title, scripts, and styles.
> 2. `header` is a set of components that are laid out horizontally and appears _before_ the `beforeBody` section. This enables you to replicate the old Quartz 3 header bar where the title, search bar, and dark mode toggle. By default, Quartz 4 doesn't place any components in the `header`.

Quartz **components**, like plugins, can take in additional properties as configuration options. If you're familiar with React terminology, you can think of them as Higher-order Components.

See [a list of all the components](component.md) for all available components along with their configuration options. You can also checkout the guide on [[creating components]] if you're interested in further customizing the behaviour of Quartz.

### Style

Most meaningful style changes like colour scheme and font can be done simply through the [[configuration#General Configuration|general configuration]] options. However, if you'd like to make more involved style changes, you can do this by writing your own styles. Quartz 4, like Quartz 3, uses [Sass](https://sass-lang.com/guide/) for styling.

You can see the base style sheet in `quartz/styles/base.scss` and write your own in `quartz/styles/custom.scss`.

> [!note]
> Some components may provide their own styling as well! For example, `quartz/components/Darkmode.tsx` imports styles from `quartz/components/styles/darkmode.scss`. If you'd like to customize styling for a specific component, double check the component definition to see how its styles are defined.
