<p class="intro">Events are normally used in combination with functions, and the function will
not be executed before the event occurs!</p>

<h2>Event Handlers</h2>
<p>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.</p>
