Svelte Basics - Slots
Components in Svelte can also have content placed inside of them as a “child”. To tell Svelte where you want that content to be located, we use a
<slot />. By default, any content added inside when a component is used will be located where the slot was placed. We can also have multiple children of a component by using named slots. We give each component a name, and then tell the component which slot to place the content in when the component is rendered.
