To apply this theme in the specific page, you have to add following line at that page
<!doctype html> <html> <head> <meta name="layout" content="main"/> <title>Welcome to Grails</title> <asset:link rel="icon" href="favicon.ico" type="image/x-ico" /> </head> <body>
// content
</body> </html>

<div class="jumbotron">
<h1> {{$page_title}}</h1>
<p> {{$page_description}}</p>
<h4>About Page : <a href="{{ url('/site/about') }}">Go To About Page</a> </h4>
</div>
