# Layout

Layout settings in **Theme settings > Layout** control storefront horizontal margins, default spacing rhythm, and optional vertical scroll snapping for supported sections.

## How to change theme layout

{% stepper %}
{% step %}

#### Set margin and gap

* Open **Theme settings > Layout**.
* Set **Horizontal margin** to **Narrow**, **Standard**, **Wide**, or **Full**.
* Set **Gap size** (1–20 px) for default spacing in supported layouts.
  {% endstep %}

{% step %}

#### Optional: scroll snapping

* Turn on **Enable scroll snapping** if you want sections to snap to the viewport while scrolling.
* Open individual sections and set **Scroll snap alignment** where needed; leave **None** on sections that should scroll normally.
  {% endstep %}

{% step %}

#### Preview long pages

* Scroll home, collection, and landing templates on desktop and mobile.
* If snapping feels too rigid, turn off global snapping or clear alignment on most sections.
  {% endstep %}
  {% endstepper %}

### Notes on layout

* **Horizontal margin** changes overall content width; **Full** uses the maximum width the theme allows for that template.
* **Gap size** applies where layouts read this global value—verify on real sections.
* Scroll snapping only applies where a section supports **Scroll snap alignment**; it is off by default.

## 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://help.brickspacelab.com/slab/getting-started/global-settings/layout-settings.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.
