Neither the background body > color or the rotating image works. does php interpret the file or not? you can decide it if you request the css file directly with a browser. if you see <?php and code in it, it is not interpreted. a possible solution for that: "Use .htaccess to force your .css files to *really* be PHP files: <Files ~.css> ForceType application/x-httpd-php </Files>" (quoted from Richard Lynch's earlier post) another problem may be if you do not send correct content-type header. the first line should be something like <?php header('Content-type: text/css'); ?> before the css stuff. hope that helps Zoltán Németh > > thanks > > -- > ::Bruce:: > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
