<hr />
<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 attributes that can be inserted into HTML tags to define event
actions.</p>
<p>If you want to learn more about programming with these events, you should
study our <a href="../js/default.asp">JavaScript tutorial</a> and our <a href="../dhtml/default.asp">
DHTML tutorial</a>.</p>
