The main goal of this chapter is to provide an introduction to PrimeNG themes, layouts, and the concepts involved. The theming concept used in PrimeNG is similar to the jQuery ThemeRoller CSS Framework (http://jqueryui.com/themeroller). PrimeNG components are designed to allow a developer to integrate them seamlessly into the look and feel of an entire web application. At the time of writing, there are 17 free themes and 5 premium themes and layouts. Free themes include ThemeRoller themes, a Twitter Bootstrap theme, and some custom themes powered by PrimeFaces and PrimeNG. Such themes are distributed along with PrimeNG itself under Apache License.
In Chapter 1, Getting Started with Angular and PrimeNG, we showed three possible setups and theme installations. You can also play with the free themes in the PrimeNG showcase (https://www.primefaces.org...
