Events in HTML

As well as attributes, events can be defined in HTML tags. Events, instead of giving values to the elements like the attributes, trigger actions when they occurs. These actions are defined by client-side scripts that are programs written to perform some action in a specific language (e.g., JavaScript, VBScript, etc.). There are different events that occurs in different instances according to browsers or users actions.
