Web Part Overview
Web parts are an essential element of a Kentico CMS website. They are the primary way that developers deploy new application features and content editors, authors and publishers interact and view content on your Kentico CMS site. Web parts are the basic building blocks of page templates and are used to modify, view and control page appearance directly from a browser. Technically they are ASP.NET controls that are added to a Kentico CMS web part zone.
