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.
