Issue number: internal
---------
## What is the current behavior?
Card content has no encapsulation.
## What is the new behavior?
Converted `ion-card-content` to Shadow DOM which improves consistency among components & CSP compatibility.
## Does this introduce a breaking change?
- [x] Yes
- [ ] No
BREAKING CHANGE:
The `ion-card-content` component has been updated to Shadow DOM. With this update, all card-related components now use Shadow DOM for style encapsulation. There should not be any breaking changes related to targeting inner elements since `ion-card-content` does not have any internal elements of its own. However, some user styles may break due to the removal of the `card-content-{mode}` class or changes in selector specificity.
The default styles for heading elements inside `ion-card-content` have been removed. If you need custom styling for headings, you can add your own CSS targeting these elements.
For example:
```css
ion-card-content h1 {
margin-top: 0;
margin-bottom: 2px;
font-size: 1.5rem;
}
ion-card-content h2 {
margin-top: 2px;
margin-bottom: 2px;
font-size: 1rem;
}
ion-card-content h3,
ion-card-content h4,
ion-card-content h5,
ion-card-content h6 {
margin-top: 2px;
margin-bottom: 2px;
font-size: 0.875rem;
}
```
