Events are normally used in combination with
functions, and the function will not be executed before the
event occurs!
New to HTML 4.0 was the ability to let HTML events trigger
actions in the browser, like starting a JavaScript when a user
clicks on an HTML element. Below is a list of the attributes
that can be inserted into HTML tags to define event actions.
