# Child Theme – CSS Compression error

 * Hi Frank,
 * I enqueued my own CSS in a child theme functions.php. Everything works fine untill
   I switch on the CSS compression with Autoptimize plugin.
    The front page is blank
   and a message display with “connection error”. Usually I never encounter any 
   issue ¯\_(ツ)_/¯
 * So, my question is: Does the wp_enqueue_style child theme function requiered 
   a specific information for rolling peacefully with the CSS compression?
 * Here an excerpt of my functions.php.
 *     ```
       function oxy_load_child_scripts() {
         wp_enqueue_style( THEME_SHORT . '-child-theme' , get_stylesheet_directory_uri() . '/style.css', array( THEME_SHORT . '-theme' ), false, 'all' );   
   
         // MY STYLE
           if ( is_front_page () ) {
                 wp_enqueue_style( 'rotating-words', get_template_directory_uri() . '/../angle-child-theme/assets/css/rotating-words.css' );
           }
         }
         add_action( 'wp_enqueue_scripts', 'oxy_load_child_scripts');
       ```
   
 * Thank you for your help and merry christmas!

 * The blank page problem is probably due to the CSS-minification tool ([https://github.com/tubalmartin/YUI-CSS-compressor-PHP-port](https://github.com/tubalmartin/YUI-CSS-compressor-PHP-port))
   is crashing on your child theme CSS. If the problem is only with the frontpage,
   then rotating-words.css is probably triggering something. This could be due to
   a problem with the CSS itself or a problem with the minification-tool. If you
   can provide me with (a link to) that file, I’ll be happy to have a look at what
   might be happening.

 * (you could, off course, also simply exclude rotating-words.css from CSS optimization)

 * Wow, awesome quick support for an awesome free plugin!
    I currently work on localhost…
 * If you confirm me that wp_enqueue_style is correct, the problem should be probably
   mine. I inspect my CSS :/
 * Thanks

 * well, wp_enqueue_style should work, so indeed something in rotating-words.css
   is indeed crashing the minifier (although the minifier might be to blame as well).
   you can also test on the CSS minificatoin on [http://futtta.be/cssmin/gui/](http://futtta.be/cssmin/gui/)

    Have yourself a Merry Christmas!

 * Hi Frank,
 * first let me thank you for the major update of Autoptimize.
    My problem of blank
   page disappears. I simply split the huge rotating-words.css into two files. I
   have no idea why this is working now, but this thead could be definitively closed.

 * happy to hear it works now pixelmort!
 * regarding that rotating-words.css; what you would also do is minify it yourself
   and save it as rotating-words.min.css, in which case AO 2.0 would not try to 
   minify it any more, but will inject it in the autoptimized file after the minification
   has been done.
