{QUOTE(replyto="getbootstrap.com")}Bootstrap is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web.{QUOTE}

Since Tiki 13 our Smarty templates changed to produce Bootstrap compatible HTML. Since Tiki 14 our theme system was completely rewritten so instead styles/ and separate templates/ folders all the themes reside in themes/ folder now.

Every developer should make sure that Tiki produces valid HTML5 and check if the structure is Bootstrap compatible.
