# Élément d'en-tête

Vous pouvez utiliser le cmdlet `New-UDHelmet` pour ajouter des balises d'élément `<head>` telles que `<script>` et `<style>` à vos pages. Cela 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 vous devrez peut-être ajuster la configuration du serveur web pour les prendre en charge.

```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' 
} -Children { 
    "body { background-color: 'red'}" 
}
```

## Application

Vous pouvez également charger des feuilles de style et des scripts directement depuis l'application.

```powershell
New-UDApp -Content {

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