# How to: Center Text With PDF-Upload Merge Fields

By default, PDF-upload merge fields align text to the left.

This matters when you need text to sit in the middle of a form field, not the left side.

Use **Additional Style** to control alignment for a PDF-upload merge field.

To center text, set both a `width` and `text-align:center`.

{% hint style="info" %}
`text-align:center` alone usually does not work.

Add a `width` so S-Docs knows the area to center within.
{% endhint %}

### Common examples

#### Center across the page

Use this for text that should center across a standard letter-width area:

```
width:8in;text-align:center;
```

#### Center inside a smaller area

Use this when the field sits inside a smaller box or section:

```
width:100px;text-align:center;
```

Replace `100px` with the width of your target area.

## 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.sdocs.com/sdocs/template-architecture/document-formats/pdf-upload-format/centering-text-in-pdf-upload-merge-fields.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.
