If you’re anything like me or my clients, you probably can’t think of anything you care less about than the Gutenberg block editor. If you’ve had a gutful of your website performance being unnecessarily penalised and/or causing presentation conflicts because of the forced block editor styles, then this this plugin is for you.
FYI: This plugin kills front-end block editor CSS for WordPress core, WooCommerce and the Storefront theme. You’re welcome.
It goes without saying (I’ll say it anyway) that if you rely on the block editor for front-end presentation, then steer clear of this plugin.
<h3>How to use</h3>
<ul>
<li>Just activate this plugin, nothing to configure.</li>
<li>Get on with the rest of your day (optional).</li>
</ul>
<h3>How it works</h3>
This plugin simply runs a function to dequeue the aforementioned Gutenberg styles from the front-end of your website. It does not interact with your database.

If you’ve ever wanted to control how a particular part of your page or posts looks without having to modify the theme files or stylesheets, 
this is a simple plugin that allows you to do that.
Once installed and activated, you’ll have a new settings panel in the WordPress admin that will provide you with a text area block 
where you can include any styling you’d like to use, and a second input field that allows you to insert a comma delimited list of page 
or post IDs to apply these styles to.
Alternatively, you can enter ‘ALL’, and have your styles applied on every page/post.
