<meta http-equiv=”X-UA-Compatible” content=”IE=EmulateIE7” />But in Joomla, if you use the recommended way to insert a stylesheet into your template (using $document->addStyleSheet) AND you want your <title> to come first, you cannot easily add this code without hacking core files. So to achieve this you can insert this line in Joomla index.php using the following code BEFORE your $document->addStyleSheet code.
$this->setMetaData( ‘X-UA-Compatible’, ‘IE=EmulateIE7’, true );
