Did you ever read about Optimization of website/blog through ordering styles and Scripts in head section? 
If you like your website load in browser as quickly as possible then you may have read in performance optimization tips that 
you should move all CSS files on top and script at last in HTML head section <head></head>.
How do you order those calls? If you are manually putting CSS and JavaScript files in head section (<head></head>), 
then you can do this very easily. Just modify once and optimization for this is over. 
What if you are using plugins and that are adding calls to JavaScript and CSS files dynamically. This is case of WordPress blog, 
where we use many plugins and those plugins add various Styles and Script files dynamically from wp_head() call.
If above lines, do not makes much sense to you then probably you have not 
read this documentation on <a href="http://code.google.com/speed/page-speed/docs/rtt.html#PutStylesBeforeScripts" rel="nofollow ugc">Google</a>.
The plugin will also collect different inline scripts to one place. Thus making the source code 
look better.
To check, if the plugin is doing anything or not, compare the Head section before and after 
activating the plugin.
(For reading more details discussion, follow the Plugin link on right side.)

WP Add Custom CSS allows you to add custom CSS to the whole website and to individual posts, pages and custom post types (such as Woocommerce products). 
The CSS rules applied to the whole website will override the default stylesheets of your theme and plugins, while the CSS rules applied to specific pages, posts or custom post types will override the main stylesheet too.
The plugin works with the most popular builders, such as Elementor, Gutenberg and the Classic Editor.
You can edit the main stylesheet from the the “Add custom CSS” settings page. 
The plugin also creates a new “Custom CSS” box in the editing area to add custom CSS to specific posts, pages and custom post types.
Select the preferred CSS output method from the plugin’s settings page to ensure seamless integration with caching and minification plugins or to improve above-the-fold rendering performance.
