# Style
All elements support:
```json
{
"padding": 12,
"background": "#1a1a2e",
"cornerRadius": 8,
"opacity": 0.9,
"frame": { "width": 100, "height": 50, "maxWidth": "infinity" },
"border": { "color": "#333333", "width": 1 },
"shadow": { "color": "#000000", "radius": 4, "x": 0, "y": 2 },
"clipShape": "circle",
"flex": 1
}
```
#### `clipShape` — Content Masking
Clips the element's content to a shape. Useful for circular avatars, pill-shaped badges, etc.
| `"circle"` | Perfect circle (50% border-radius) |
| `"capsule"` | Pill shape (fully rounded ends) |
| `"rectangle"` | Rectangle with `cornerRadius` applied |
> **Platform mapping:** SwiftUI `.clipShape()`, CSS `border-radius` + `overflow: hidden`, Android Glance shape clipping.
#### `flex` — Proportional Layout
The `flex` property allows elements to occupy available space proportionally within stacks, analogous to CSS `flex`, Android `layout_weight`, or SwiftUI `layoutPriority`.
```json
{
"type": "hstack",
"children": [
{ "type": "text", "content": "Left", "flex": 1 },
{ "type": "text", "content": "Center (wider)", "flex": 2 },
{ "type": "text", "content": "Right", "flex": 1 }
]
}
```
