## Views and forms
Views: canvas, corner, chip. Canvas forms: landscape, portrait, square.
[Card views, themes and publishing](/docs/cards/). [Browse the gallery](/apps/#cards).
## Data and privacy
This card uses its configured properties and live card data.
## Properties
For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).
Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

## Canvas example
Add this item to a playlist page’s `primitives`. [Publish the playlist and assign a screen](/docs/cards/#publish-a-card-canvas).
```json
{
"id": "sensors",
"primitive": "card",
"card": "sensors",
"major": 1,
"params": {
"theme": "neomustard"
},
"rect": {
"x": 0,
"y": 0,
"width": 1920,
"height": 1080
},
"layer": 0,
"content_fit": "fill",
"data": "sensors-main"
}
```
## Write live data
Create this document before showing the card, then replace it to update the screen without republishing. Use the same project as the playlist. Supply your API authorization through the environment; see [API authentication](/docs/authentication/).
```console
curl --request PUT "https://api.screenrig.ai/api/card-data/sensors-main" \
--header "Authorization: Bearer $SCREENRIG_TOKEN" \
--header "ScreenRig-Project: $SCREENRIG_PROJECT" \
--header "Content-Type: application/json" \
--data '{"document":{"sensors":[{"label":"Example","value":1}],"updatedAt":null}}'
```
