Lessons
Add content inside an element at start or end.
append() and prepend() is easiest to learn by reading the example, changing it, and observing the result.
$('#list').append('<li>Added at the end</li>');
$('#list').prepend('<li>Added at the start</li>');
$('#title').before('<p>Inserted before</p>');
$('#title').after('<p>Inserted after</p>');Practice the append() and prepend() example in a small scratch file, then explain what changed and why.
