# Elemento head

Puede utilizar el cmdlet `New-UDHelmet` para añadir etiquetas de elementos `<head>` como `<script>` y `<style>` a sus páginas. Esto resulta útil para incluir JavaScript o CSS alojados externamente.

## JavaScript

Puede cargar JavaScript utilizando la etiqueta script con el atributo `src`. Tenga en cuenta que pueden aplicarse limitaciones sobre los recursos entre sitios y que quizá tenga que ajustar la configuración del servidor web para admitirlo.

```powershell
New-UDApp -Content {
    New-UDHelmet -Tag 'script' -Attributes @{ src = "https://www.mycdn.com/site.js" } 
}
```

## CSS

Puede cargar CSS utilizando la etiqueta `link`.

```powershell
New-UDHelmet -Tag 'link' -Attributes @{ 
    rel = 'stylesheet' 
    href = "mystylesheet.css"
} 
```

## Estilos

Puede utilizar una etiqueta `style` para proporcionar estilos directamente.

```powershell
New-UDHelmet -Tag 'style' -Attributes @{ 
    type = 'text/css' 
} -Children { 
    "body { background-color: 'red'}" 
}
```

## Aplicación

También puede cargar hojas de estilo y scripts directamente desde la aplicación.

```powershell
New-UDApp -Content {

} -Stylesheets "mysheet.js" -Scripts "mysite.js"
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/powershell-universal/es/aplicaciones/components/utilities/head-element.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
