Beautifulck Widget CK adds a ‘Beautiful Me !’ option on your widgets. You can click on it and let the magic do the job.
You can select a theme for your widget title (banner, corner, glossy…), the font color and size and an icon for it. 
You can set the background color with gradient, border radius, border color, shadow and more on the widget. 
The options are made to let you control the way to show your widget with nice colors and the place of your title. 
The admin interface is ajax based and show you a direct preview of your styles selection and how will render your widget.

It adds a syntax-highlighted CSS Editor where you can add additional CSS to your Gutenberg Blocks to style them the way you want.

Blocks CSS: CSS Editor for Gutenberg Blocks

This is must have plugin for Gutenberg Block Editor. Makes it so much easier to add css classes where you use the blocks! 

Excellent!

I think I just would not be able to use the block editor without this. Thank you so much for this plugin!

This plugin saved my life!


This is a great tool for what it does. The only confusing thing for me is that it says on .org that you have 11 blocks.  I couldn't spot any new ones after installing this plugin, nor found any settings.


This is a great tool for those wanting to use core blocks


Can't think of Block Editor without this. Tiny powerful thing. 



Only thing I hate in this plugin is the following line:



$render_css = empty( $file_name ) || strpos( $file_name, 'post-v2' ) === false;



This means if you deactivate Otter, your content might just break :(
