Component Slot
By adding the <slot></slot> tag in the template, you can place the content inside the corresponding component label's slot when using the component.
Custom components do not have a defined 'display' property by default, so it needs to be defined manually. In the component's style, the ':host' selector can be used to add styles specific to the component itself.
This example demonstrates how to create a component called simple-btn. The template of the component includes a slot where content can be inserted into the component. The component is styled by adding the :host selector to its styles. In another page, the simple-btn component is referenced using the l-m component and content is inserted into it.
