Struggling with adding multiple CSS classes to your WordPress blocks? CSS Class Manager simplifies the process with autocomplete suggestions and a dedicated manager for adding, editing, and organizing your classes. Boost your block styling efficiency!
There are two main motivations behind creating this plugin: 
Limitation of Block Style – When applying a block style, only one CSS class can be added to a block. Unfortunately, the block editor lacks the ability to select multiple block styles. To address this, users must resort to the Additional CSS Class(es) inspector control to apply multiple classes. CSS Class Manager provides a powerful manager and an autocomplete inspector control, enabling users to easily add and apply CSS classes to their blocks. 
Poor UX of the Additional CSS Class(es) control – The default control for adding class names is a simple text input. This can be cumbersome, especially when applying CSS classes frequently. With the custom inspector control provided by CSS Class Manager, users can effortlessly add their class names, enhancing the user experience.

CSS Class Manager – An advanced autocomplete additional css class control for your blocks


For years I used the Editors Kit plugin for the sole purpose of the CSS Class Management. However, though the years that plugin became a disaster, with lots of garbage added to it.



Thankfully I found this little gem. The only thing that I want to add as a Wishlist, that the Editors Kit has is to export the custom CSS classes in php as well, so we can simply include that code in our plugins/themes, so we don't have to import/export the json files with each site installation.



Nevertheless, this is one of my must use plugins for every site, since I have dozens of custom CSS classes to deal with.



I can not express enough my gratitude, YOU ROCK !!!


I really REALLY appreciate this.
