# Theme

**Beautiful User Profiles: The theme gives you more options to choose from. Simply pick the one that best design. If that is not enough, control the position of the user's avatar and its size, as well as the profile cover height.**

**Paint The Chat: Chose the colors for a chat so it can really “pop” from the rest of the site.**

**Group Avatar and Cover Sizes: Change the sizes and height of group avatars and covers.**

**Pinned Posts Style: Highlight pinned posts by changing the border size and color to make them stand out more.**

**Photos In-Stream: Change the width of individual photos or the entire gallery.**

**Responsive:** Works great on phones, tablets, and other mobile devices.

**Flexible Layout:** Fluid or fixed width, different sidebar sizes, columns gap.

**Browser Support**: Supports all modern desktop browsers.

**Lightweight**: Super-fast loading times unobstructed by redundant scripts.

## 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://fmtlol.gitbook.io/docs/theme.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.
