# Card
## class **Card**
{% hint style="warning" %}
Do not create **Card** instances directly. Instead, use the `create_card()` method of the [CardContainer](/ui-scripting/api-reference/cardcontainer.md) class to genereate them.
{% endhint %}
{% hint style="info" %}
Nesting multiple Cards is prohibited.
Cards must be a direct children of the [CardContainer](/ui-scripting/api-reference/cardcontainer.md).
{% endhint %}
#### Constructor
```python
# Basic example
card = container.create_card() # Default type of "columns"
# Custom properties
container = tab.create_container(
type="columns",
height: "auto",
width: "auto",
vertical_align: "center",
horizontal_align: "center",
gap: 4,
disallow_shrink=True
)
# Rows example
container = tab.create_container(type="rows")
```
| Parameter | Description | | |
| ----------------- | --------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| type |
Prevents the card from shrinking when its width or height is set to auto. Useful when cards adjust their size to fit other elements in the tab. Set to True to disable shrinking. Leave it as default if no issues occur, as forcing this may cause unexpected layout behavior.
