# Question containers
Questions can have an overlay on top of the default styles applied to them, which gives the user a degree of freedom in defining how different questions and content components can appear on the page.
Any theme provided by Formsort will have at least one container style - default - but you can build up your collection of different styles by heading to **Containers** in the Theme editor.
**+Add question style** allows you to create a new question container.
{% hint style="info" %}
The **Label margin** is of particular note here, since it provides spacing between the Question label the buttons/input bars related to it.
{% endhint %}
Once a container style is defined, any question can use any of the container styles by clicking the question, and choosing the container style in the **Question container style** dropdown in the Style menu.
These containers are helpful to make different kinds of questions visually distinct: a common pattern is to create an **optional** question class that is used for optional questions, with left border and margin to differentiate it from non-conditional questions.

## 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://docs.formsort.com/styling/customizing-appearance/question-containers.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.
