# Head Element

Use the New-UDHelmet cmdlet in PowerShell Universal to inject head tags like script, link, and style elements for loading external JavaScript and CSS.

You can use the `New-UDHelmet` cmdlet to add `<head>` element tags like `<script>` and `<style>` to your pages. This is useful for including externally hosted JavaScript or CSS.

## JavaScript

You can load JavaScript by using the script tag with the `src` attribute. Note, limitations on cross-site resources may be in affect and you may need to adjust the web server configuration to support this.

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

## CSS

You can load CSS using the `link` tag.

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

## Styles

You can use a `style` tag to provide styles directly.

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

## App

You can also load stylesheets and scripts from the app directly.

```powershell
New-UDApp -Content {

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

# Agent Instructions

## 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/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.
