  • Essential for pro developers

    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.

  • Need responsiveness? You need this plugin!

    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.

  • Best block CSS plugin out there right now

    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.

  • must-have plugin

    An awesome and must-have plugin if you know your way around writing CSS.

  • Simple CSS editor for blocks!

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

  • Extremely useful tool for speeding up your workflow

    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!
