This section explains the general guidelines that designers should follow when adding/modifying HTML and CSS in their XperienCentral project as well as how a design that should be implemented within XperienCentral. The definition of a design here is a set of HTML, CSS, JS files and other related artifacts that are needed to render the intended look-and-feel of content within the intended browser and/or device. For a dynamic website, you do not want the page content and the structure (navigation) of the site to be strictly fixed beforehand. A good design should consist of one or more flexible HTML templates.
