Different Browsers Compatible Code

This is not a specific question but related to specific problem. I am working on some app. I am using Twitter bootstrap in it. Through my whole development i used google chrome for testing in local host. When a section a came where i had to upload and render picture on the page, when i scrolled down the alignment started distorting. I became frustrated.

After some time i tried that code(CSS) on mozilla firefox. It worked fine. Now i am confused that why is it happening. As if my code runs fine on firefox then it seems my code is correct.

Thanks for your help.

Sometime problem in CSS or JS for different browser (check use firebug)

but, if the problem in Yii (PHP), may you need to enable YII_DEBUG in index.php, to see error message.


defined('YII_DEBUG') or define('YII_DEBUG',true);
