There are many ways to style a block... however, this plugin makes block targeting a none issue. That said, and by far, the biggest benefit of this plugin is the ability to create complex reusable blocks and patterns including all the necessary CSS rules all in one shot. How is it that this plugin does not have a gazillion active installs is maddening to me ! P.S. And I posted this in my Getwid review, Getwid does not work with Block CSS. It would be great if the developers of one of these 2 plugins fixes this issue... Thanks, Nick.

Easy simple and a time saving plugin to configure your blocks pixel-perfectly. You just need to learn CSS... grid, flexbox, object-fit, media-queries, and much more!
