# Elemento head

È possibile utilizzare il cmdlet `New-UDHelmet` per aggiungere tag dell'elemento `<head>` come `<script>` e `<style>` alle proprie pagine. Ciò è utile per includere JavaScript o CSS ospitati esternamente.

## JavaScript

È possibile caricare JavaScript utilizzando il tag script con l'attributo `src`. Si noti che potrebbero essere in vigore limitazioni sulle risorse cross-site e potrebbe essere necessario modificare la configurazione del server web per supportarlo.

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

## CSS

È possibile caricare CSS utilizzando il tag `link`.

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

## Stili

È possibile utilizzare un tag `style` per fornire stili direttamente.

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

## App

È inoltre possibile caricare fogli di stile e script direttamente dall'app.

```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/it/app/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.
