fx-include lazily loads markup from a local template or external HTML source into its own light DOM immediately or when a configured event occurs.
The included content is loaded immediately into the page. Usually used for modularizing pages for easier editing.
Inclusion when receiving configured event. Used for lazy-loading sections.
Default behavior: loads once and removes the event listener.
Bound output:
With reload, every click clears and recreates the included content.
Timestamp:
Loads an external HTML file once and selects one fragment from it using a CSS selector.
The placeholder element is replaced by the included content.
This section now stands where the include placeholder used to be.
