## Types
### Head
Typescript base schema for document <head>.
```ts
export interface Head<E extends MergeHead = MergeHead> extends BaseHead {
/**
* The <title> HTML element defines the document's title that is shown in a browser's title bar or a page's tab.
* It only contains text; tags within the element are ignored.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/title
*/
title?: string
/**
* The <base> HTML element specifies the base URL to use for all relative URLs in a document.
* There can be only one <base> element in a document.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base
*/
base?: Partial<Merge<E['base'], Base>>
/**
* The <link> HTML element specifies relationships between the current document and an external resource.
* This element is most commonly used to link to stylesheets, but is also used to establish site icons
* (both "favicon" style icons and icons for the home screen and apps on mobile devices) among other things.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/link#attr-as
*/
link?: (Link & DataKeys & DefinedValueOrEmptyObject<E['link']>)[]
/**
* The <meta> element represents metadata that cannot be expressed in other HTML elements, like <link> or <script>.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta
*/
meta?: (Meta & DataKeys & DefinedValueOrEmptyObject<E['meta']>)[]
/**
* The <style> HTML element contains style information for a document, or part of a document.
* It contains CSS, which is applied to the contents of the document containing the <style> element.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/style
*/
style?: (Style & DataKeys & DefinedValueOrEmptyObject<E['style']>)[]
/**
* The <script> HTML element is used to embed executable code or data; this is typically used to embed or refer to JavaScript code.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script
*/
script?: (Script & DataKeys & DefinedValueOrEmptyObject<E['script']>)[]
/**
* The <noscript> HTML element defines a section of HTML to be inserted if a script type on the page is unsupported
* or if scripting is currently turned off in the browser.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/noscript
*/
noscript?: (Noscript & DataKeys & DefinedValueOrEmptyObject<E['noscript']>)[]
/**
* Attributes for the <html> HTML element.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/html
*/
htmlAttrs?: (HtmlAttributes & DataKeys & DefinedValueOrEmptyObject<E['htmlAttrs']>)
/**
* Attributes for the <body> HTML element.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/body
*/
bodyAttrs?: (BodyAttributes & DataKeys & DefinedValueOrEmptyObject<E['bodyAttrs']>)
}
```
### Flat Meta
See [metaFlat.ts](/src/metaFlat.ts) for the full list.
```ts
// SAMPLE
export interface MetaFlat {
/**
* This attribute declares the document's character encoding.
* If the attribute is present, its value must be an ASCII case-insensitive match for the string "utf-8",
* because UTF-8 is the only valid encoding for HTML5 documents.
* <meta> elements which declare a character encoding must be located entirely within the first 1024 bytes
* of the document.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta#attr-charset
*/
charset: string
/**
* Use this tag to provide a short description of the page.
* In some situations, this description is used in the snippet shown in search results.
*
* @see https://developers.google.com/search/docs/advanced/appearance/snippet#meta-descriptions
*/
description: string
/**
* This tag tells the browser how to render a page on a mobile device.
* Presence of this tag indicates to Google that the page is mobile friendly.
*
* @see https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta/name#standard_metadata_names_defined_in_other_specifications
*/
viewport: string | Partial<{
/**
* Defines the pixel width of the viewport that you want the web site to be rendered at.
*/
width: number | string | 'device-width'
/**
* Defines the height of the viewport. Not used by any browser.
*/
height: number | string | 'device-height'
/**
* Defines the ratio between the device width
* (device-width in portrait mode or device-height in landscape mode) and the viewport size.
*
* @minimum 0
* @maximum 10
*/
initialScale: number | string
/**
* Defines the maximum amount to zoom in.
* It must be greater or equal to the minimum-scale or the behavior is undefined.
* Browser settings can ignore this rule and iOS10+ ignores it by default.
*
* @minimum 0
* @maximum 10
*/
maximumScale: number | string
/**
* Defines the minimum zoom level. It must be smaller or equal to the maximum-scale or the behavior is undefined.
* Browser settings can ignore this rule and iOS10+ ignores it by default.
*
* @minimum 0
* @maximum 10
*/
minimumScale: number | string
/**
* If set to no, the user is unable to zoom in the webpage.
* The default is yes. Browser settings can ignore this rule, and iOS10+ ignores it by default.
*/
userScalable: 'yes' | 'no'
/**
* The auto value doesn't affect the initial layout viewport, and the whole web page is viewable.
*
* The contain value means that the viewport is scaled to fit the largest rectangle inscribed within the display.
*
* The cover value means that the viewport is scaled to fill the device display.
* It is highly recommended to make use of the safe area inset variables to ensure that important content
* doesn't end up outside the display.
*/
viewportFit: 'auto' | 'contain' | 'cover'
