# Slides

```gistui
root = Slides(Slide(Header("GistUI", "Generative UI, engineered for production", size:xl, align:center), layout:center, bg:inverse), Slide(Header("Why", "Three reasons"), Grid(Tile("Fast", "Each line is parsed once", icon:rocket), Tile("Safe", "Programs cannot run code", icon:shield), Tile("Small", "74 KB first load", icon:sparkles), cols:3)), v:viewer, title:"Launch deck")
```

## Signature

This is the line a model reads in the system prompt.

```gistui
Slides(...Slide, title:str, subtitle:str, v:deck|viewer, ratio:str)
```

- **Group:** Layout
- **Children:** Yes: Slide
- **Positional arguments:** none
