Behaviour is a small library that is used to attach JavaScript events to an HTML page without adding additional markup. This is accomplished by using CSS selectors, which apply JavaScript to matching HTML elements. Such a matching system is useful for keeping markup clean, and it helps make your JavaScript more reusable. The library is bundled with HTML_AJAX, and its usage is explained in Chapter 9, "Libraries Used in Part II: HTML_AJAX."
