# Text Box
Similar `Text Frames`, but the difference being that it is `VML` `Shape` based.
!> `Text Boxes` requires an understanding of [Paragraphs](usage/paragraph.md).
> `Text boxes` are paragraphs of text in a document which are positioned in a separate region or frame in the document, and can be positioned with a specific size and position relative to non-frame paragraphs in the current document.
## Intro
To make a `Text Box`, simply create a `Textbox` object inside the `Document`:
```ts
new Textbox({
alignment: "center",
children: [
new Paragraph({
children: [new TextRun("Hi i'm a textbox!")],
}),
],
style: {
width: "200pt",
height: "auto",
},
});
```
