In Svelte, slots are placeholders inside a component that allow you to pass custom content from a parent component into a child component. This makes components more flexible and reusable, similar to how children are passed in React using props.children.
Here, the <slot> in Card.svelte is replaced by whatever content is placed between <Card>...</Card> in the parent component.
You can create multiple slots and name them to control where specific pieces of content should go.
Named slots let you define specific areas like header and footer, making your component structure more organized.
You can provide default content inside a <slot>. This content will be used when the parent does not provide anything for that slot.
Slots allow passing custom content into a child component.
Use a plain <slot> for default, single content areas.
Use name attributes to create multiple, named slots.
Provide fallback content for better usability and defaults.
