No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. The recent download trend is too spiky to read.

    An essential add-on for anyone wanting to make as much use of a proper CSS-first approach to development without relying on a myriad of styling inputs which often don’t offer the control that you need. This plugin is lightweight and just adds in the functionality required to add whatever custom styling any individual block requires and the developer was blazingly quick in fixing an issue I experienced as well as introducing a new feature I’d requested (the ability to define our own class names rather than having them auto-generated). Highly recommended.

    Until FSE theme blocks can have different styles on different screen sizes this is a must for any custom theme builder out there.Maybe hard to use for end users (content creators), but for site builders it should be natural.

    By far the best block CSS editor of any of the others I’ve tried, especially with its efficiency functions like the automatic selection and minifying. This has been an immense lifesaver.

    Does exactly what it is supposed to do and also has support for me advanced styling (media queries, CSS variables, etc.). Awesome!

    As a seasoned WP developer often working on tight timelines and sometimes on tight budgets, this is such an important tool. Thank you for making it! Inline block styles are such an efficient and performant way to quickly customise the styles of blocks. Love it!

    This is exactly what I need. Very easy to use. Love that you can scope to current item with [block] {} JANUARY 2025 UPDATE: after a year of use and having installed on at least 20 client sites, I now look at this as indispensable to my work as a website developer. No complaints whatsoever. This topic was modified 1 year, 5 months ago by James Revillini. Reason: to reiterate the awesomeness
