Add content at the beginning of an element and understand how existing nodes and multiple destinations affect the result.

Add content at the end of an element, compare insertion with moving or cloning nodes, and handle user input as plain text.

Explore case-sensitive substring matching, descendant text, and a safer way to handle dynamic search strings without constructing selectors.

Check how :button treats button elements, ordinary button inputs, and submit or reset inputs, with a working selection example.
