# Advanced

**Advanced** is the group of sections for merchants who need something the standard sections do not cover, such as an app snippet, a tracking widget, or a small piece of custom markup. Instead of editing theme files, you drop the code into a section and place it anywhere on the page like any other section. Shoppers do not see the group itself, only whatever the code you add renders on the page.

Read this group last. Try the ready made sections in [Banners](/velare/customize-your-pages/banners.md), [Products](/velare/customize-your-pages/products.md), or [Storytelling](/velare/customize-your-pages/storytelling.md) first, and reach for Advanced only when none of them produce the result you need.

### Where to find it <a href="#where-to-find-it" id="where-to-find-it"></a>

{% hint style="success" %}
**Steps:**

1. Go to **Online Store > Themes > Customize**.
2. Open the template you want to edit, for example the homepage.
3. Click **Add section**.
4. Open the **Advanced** group and choose the section you need.
   {% endhint %}

*Result:* the section is added at the bottom of the template, and you can drag it into position in the left sidebar.

### Sections in this group <a href="#sections-in-this-group" id="sections-in-this-group"></a>

| Section                                                                 | What it does                                                                                                                             | Use it when                                                                                                      |
| ----------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- |
| [Custom Liquid](/velare/customize-your-pages/advanced/custom-liquid.md) | Renders your own Liquid, HTML, CSS, or app snippet inside a normal section slot, with the theme width and color scheme applied around it | An app asks you to paste a snippet into a page, or you need a small piece of markup no built in section provides |

### Suggested reading order <a href="#suggested-reading-order" id="suggested-reading-order"></a>

1. Confirm no standard section already does the job. A built in section keeps working through theme updates, custom code is yours to maintain.
2. Read [Custom Liquid](/velare/customize-your-pages/advanced/custom-liquid.md) and note the width and color scheme settings, because they are what make custom code sit correctly beside the rest of the page.
3. Duplicate your theme before pasting anything, so you always have a copy to fall back on.

### Related pages <a href="#related-pages" id="related-pages"></a>

* [Custom Liquid](/velare/customize-your-pages/advanced/custom-liquid.md): the only section in this group
* [Layout](/velare/set-up-your-store/layout.md): the page width that **Fixed width** follows
* [Colors](/velare/set-up-your-store/colors.md): where the color schemes come from
* [Custom CSS](/velare/customize-your-pages/custom-css.md): for styling rules that apply across the whole store rather than one section

## 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://uxsmart.gitbook.io/velare/customize-your-pages/advanced.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.
