Project: form
Task (easy): JS class Question constructor params are: title (string), name (string), and has a member 'root'. 'Question.root' is a fieldset (class 'q', id equals to param name) contains a title legend (class 'q-title') and a body container (class 'q-body'). Save codes to es-module 'common/Question.js' imported by 'index.js'. Create a Question instance (title 'sample empty question') and prepend its root to the form, save codes to 'index.js'.
