## 説明

#### Critical CSS and Javascript

This Critical CSS plugin was built exclusively to help you remove render-blocking
resources such as CSS and Javascript. We use best practices to cautiously update
your website scripts to load after your markup has completed loading.

Our plugin also has the ability to defer scripts that are inline which tend to cause
trouble when you defer their dependent scripts. We do this to ensure that your inline
scripts will not break functionality on your site, while allowing you to benefit
from the performance gains.

### Deferring CSS and Javascript Plugin Settings

 * Ability to exclude specific and critical CSS files
 * Toggle deferring inline Javascript
 * Toggle deferring jQuery
 * Ability to exclude specific and critical Javascript files

### How to ignore a critical CSS or Javascript file

Under the Tools section in the wp-admin of your site you will find a submenu “Defer
CSS & Javascript”. Click into that page to find a text area where you can add the
file that will need to be loaded immediately and not deferred. You can add filenames
or path information to exclude. To add multiple assets to this textarea, simply 
separate them with a comma.

## インストール

 * Install the Critical CSS WordPress plugin
 * After installation, click activate on plugin and all your CSS and Javascript 
   files will automatically be deferred.
