# Head-Element

Sie können das Cmdlet `New-UDHelmet` verwenden, um `<head>`-Element-Tags wie `<script>` und `<style>` zu Ihren Seiten hinzuzufügen. Dies ist nützlich, um extern gehostetes JavaScript oder CSS einzubinden.

## JavaScript

Sie können JavaScript mithilfe des script-Tags mit dem Attribut `src` laden. Beachten Sie, dass Einschränkungen für Cross-Site-Ressourcen gelten können und Sie möglicherweise die Konfiguration des Webservers anpassen müssen, um dies zu unterstützen.

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

## CSS

Sie können CSS mithilfe des `link`-Tags laden.

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

## Styles

Sie können ein `style`-Tag verwenden, um Styles direkt bereitzustellen.

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

## App

Sie können Stylesheets und Skripte auch direkt aus der App laden.

```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/de/apps/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.
