The website, KCET homepage, is related to the Polymer Project and showcases elements written in custom JavaScript code. It appears to be a platform where contributors can access the complete authors and contributors' information for the code distributed by Google as part of the Polymer Project. The site provides a polyfill called "webcomponentsjs" that enables native custom element support for browsers without ES2015 compatibility. Additionally, it mentions functions and components required to reflect classes and constructors needed for native custom elements. Overall, it seems to offer resources and information related to web development using Polymer and its associated technologies.
