 * Hello, my site is currently being migrated to ChickenArt.com so if the link to
   the page I gave you doesn’t work, then please try [http://ChickenArt.com/](http://ChickenArt.com/)
   instead!
 * I installed the Page Speed Optimization for SEO plugin, and I checked only TWO
   boxes:
 * Minify HTML is enabled (I did NOT check the box to strip comments)
    and Optimize
   CSS Delivery is enabled. (I UNchecked Enhanced loadCSS, because it added a huge
   extra empty space to the top of my website pages.)
 * The website appears to load much more quickly (yay!) BUT it also flashes an un-
   styled version super fast right before the page loads. It’s doing this on all
   the pages, as far as I can tell. It’s very noticeable and distracting – please
   tell me what is causing this and how can I fix it?
 * thank you,
 * SHudock
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fodd-jumping%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi Shudock,
 * What you are seeing is called a [Flash of Unstyled Content](https://en.wikipedia.org/wiki/Flash_of_unstyled_content)(
   FOUC).
 * The critical CSS configuration is empty. You can view the result in the HTML 
   source:
 *     ```
       <style type="text/css" id="AbtfCSS" data-abtf>
       /*!
        * Page Speed Optimization 2.9.10
        * 
        * ------------------------------------
        *    WARNING: CRITICAL CSS IS EMPTY     
        * ------------------------------------
        */
       </style>
       ```
   
 * The plugin includes a critical CSS editor:
 * [http://becausechickens.com/?critical-css-editor=1](http://becausechickens.com/?critical-css-editor=1)
 * We have published a new CSS Optimization plugin that provides many new options
   and better optimization quality. WordPress has been blocking plugin submission
   for a week but the plugin can be downloaded from Github (an open source platform).
 * [https://github.com/o10n-x/wordpress-css-optimization](https://github.com/o10n-x/wordpress-css-optimization)
 * If you would be interested to install the new CSS Optimization plugin, you can
   simply download the zip file and unzip it in the plugin directory /wp-content/
   plugins/.
 * The new optimization plugins will replace the existing Page Speed Optimization
   plugin. The currently missing plugins are Javascript Optimization and Progressive
   Web App Optimization. Those plugins will be available soon and the plugins are
   designed to be modules that can be used together efficiently (the optimization
   plugins function together as a single plugin for optimal performance).
 * Currently available:
 * – HTTP/2 Optimization
    – Web Font Optimization – CSS Optimization
 * Later today:
    – Security Header Optimization
 * Next weeks:
    – HTML Optimization – Javascript Optimization – Progressive Web 
   App Optimization – Page Cache Optimization – HTTP Cache Header Optimization
 * The CSS editor of the CSS Optimization plugin is available with +30 themes that
   enables more efficient (and fun) CSS editing while it also contains many professional
   tools such as CSS Lint and Clean CSS (professional).
 * ![](https://i0.wp.com/pagespeed.pro/wp-content/uploads/2018/02/codemirror-css.

 * Critical CSS management is also more efficient in the new plugin so we advise
   to use the new plugin for CSS and Critical CSS optimization.
 * If you have any questions, please let us know!

 * Javascript optimization is now available as well.
 * [https://github.com/o10n-x/wordpress-javascript-optimization](https://github.com/o10n-x/wordpress-javascript-optimization)
 * ![](https://i0.wp.com/pagespeed.pro/wp-content/uploads/2018/02/js-op1.png?ssl

 * The CSS Optimization plugin (and other plugins) have been updated and will continue
   to receive frequent updates.
 * Regrettably, WordPress is still blocking the plugins. One of our team members
   is currently working on it and is waiting for a reply. Installation is currently
   only possible manually.
