# Head-element

Brug cmdletten New-UDHelmet i PowerShell Universal til at indsætte head-mærker som script-, link- og style-elementer til indlæsning af ekstern JavaScript og CSS.

De kan bruge cmdletten `New-UDHelmet` til at føje `<head>`-elementmærker som `<script>` og `<style>` til Deres sider. Dette er nyttigt til at medtage eksternt hostet JavaScript eller CSS.

## JavaScript

De kan indlæse JavaScript ved hjælp af script-mærket med attributten `src`. Bemærk, at begrænsninger for ressourcer på tværs af websteder kan være i kraft, og De kan være nødt til at justere webserverkonfigurationen for at understøtte dette.

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

## CSS

De kan indlæse CSS ved hjælp af `link`-mærket.

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

## Typografier

De kan bruge et `style`-mærke til at angive typografier direkte.

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

## App

De kan også indlæse stilark og scripts direkte fra appen.

```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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
