i am working on my final year project and making my web application on netbeans, i am a newbie to yii, i want to install bootstrap in yii, I was following this link bootstrap3.pascal-brewing.de/ , but i am not being able to understand most of the steps. Anyone please tell me how can I install bootstrap in yii by following this link. The things which bothers me are, where to write the code

<?php

$cs = Yii::app()->clientScript;

$themePath = Yii::app()->theme->baseUrl;

/**

  • StyleSHeets

*/

$cs->registerCssFile($themePath . ‘/assets/css/bootstrap.css’);

$cs->registerCssFile($themePath . ‘/assets/css/bootstrap-theme.css’);

/**

  • JavaScripts

*/

$cs->registerCoreScript(‘jquery’, CClientScript::POS_END);

$cs->registerCoreScript(‘jquery.ui’, CClientScript::POS_END);

$cs->registerScriptFile($themePath . ‘/assets/js/bootstrap.min.js’, CClientScript::POS_END);

$cs->registerScript(‘tooltip’, “$(’[data-toggle=\“tooltip\”]’).tooltip();$(’[data-toggle=\“popover\”]’).tooltip()”, CClientScript::POS_READY);

?>

<!-- HTML5 shim and Respond.js IE8 support of HTML5 elements and media queries -->

&#60;script src=&quot;&lt;?php

echo Yii::app()->theme->baseUrl . ‘/assets/js/html5shiv.js’;

?>"></script>

&#60;script src=&quot;&lt;?php

echo Yii::app()->theme->baseUrl . ‘/assets/js/respond.min.js’;
