# Typography
Control how type should look across Decky presentations.
### Define the type system
Typography defines the typographic system Decky uses when creating slides.
This can include:
* Font choices
* Headline treatment
* Body copy treatment
* Relative hierarchy and scale
Decky applies typography as a system. You do not need to format every text box manually.
You can also ask the Theme agent: “Make headlines larger and more editorial.”

## 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://decky.gitbook.io/decky-docs/brand-and-themes/typography.md?ask=&goal=
```
`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.
