# Expert settings in the theme configuration

In this section, you can add your own CSS and/or JavaScript code. As this are **"individual customisations"**, we can only provide limited support here as part of the plugin support.

> Tab "Others" => Block "Expert settings"

The **"Expert settings"** in the theme configuration are – as the name implies – aimed at experts or professionals who are experienced in dealing with individual customisations.

{% hint style="danger" %}
**Attention**: Please note that custom code can cause considerable issues or potentially dangerous vulnerabilities!

## 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://knowledge.themeware.design/knowledge-base/profi-knowledge/expert-settings-in-the-theme-configuration.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.
