could not find a solution to my problem so i'll ask here.
When i insert jQuery file, i get an error on line 2: unexpected token ILLEGAL
Code:
jQuery(document).ready(function(){
    $('body').append('
        <div id="style_selector">
        <div id="style_selector_container">
        // another chunk of code
        </div><!-- #style_selector end -->');
});
Thank you in advance
