看了網上說吧，用respond.js,要跟bootstrap在同一個域名下，在同一個域名下是什么意思呢<link rel="stylesheet" href="<?=$css_url; ?>bootstrap.min.css" /><link rel="stylesheet" href="<?=$css_url; ?>bootstrap-theme.min.css" /><link rel="stylesheet" type="text/css" href="<?=$css_url; ?>style.css"><link rel="stylesheet" type="text/css" href="<?=$css_url; ?>userstyle.css"><script type="text/javascript" src="<?=$js_url; ?>verification.js"></script><script type="text/javascript" src="<?=$js_url;?>jquery-1.11.1.js"></script><!-- HTML5 Shim and Respond.js IE8 support of HTML5 elements and media queries --> ?? ? <!-- WARNING: Respond.js doesn't work if you view the page via file:// --> ?? ? <!--[if lt IE 9]> ?? ? ? <script src="html5shiv.js"></script> ?? ? ? <script src="respond.js"></script> ?? ? <![endif]-->我應該怎么改呢，求指導呀
