Taked from KSS project site:

KSS is a javascript framework that aims to allow Ajax development without javascript. It uses stylesheets with CSS-compliant syntax to setup behaviours in the client and a set of well-defined commands that are marshalled back from the server to manipulate the DOM.

KSS was designed by the developers for making an AJAX UI's. The main concern was to get AJAX features but without losing accesibility.

The goals of KSS are:

• To have a framework for javascript in a declarative way but without using helpers that been attached with an specific technology.
• Don't lose accesibility.
• To do things in a non intrusive way. You don't change HTML for getting an accesibility version. It's the same version for all.
