# Élément Head

Utilisez l'applet de commande New-UDHelmet dans PowerShell Universal pour injecter des balises head comme les éléments script, link et style afin de charger du JavaScript et du CSS externes.

Vous pouvez utiliser l'applet de commande `New-UDHelmet` pour ajouter des balises d'élément `<head>` comme `<script>` et `<style>` à vos pages. C'est utile pour inclure du JavaScript ou du CSS hébergé en externe.

## JavaScript

Vous pouvez charger du JavaScript en utilisant la balise script avec l'attribut `src`. Notez que des limitations sur les ressources intersites peuvent être en vigueur et que vous devrez peut-être ajuster la configuration du serveur web pour prendre en charge cela.

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

## CSS

Vous pouvez charger du CSS en utilisant la balise `link`.

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

## Styles

Vous pouvez utiliser une balise `style` pour fournir des styles directement.

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

## Appli

Vous pouvez aussi charger des feuilles de style et des scripts directement à partir de l'appli.

```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/fr/applis/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.
