Instant CSS

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

Share of active installs on each version of this plugin · 92% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

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.

   I do not often write reviews but I had to ! Your plugin is just awesome ! I can write SCSS directly, there’s a live editor… What else ? Amazing job ! I can not recommend more a plugin then this one. This topic was modified 5 years, 7 months ago by netalys.

   I don’t use the Custom CSS tool, I do all my edits in the Theme Editor (I create custom themes, so I’m working in my own code, not something that will be overwritten by a theme update.) If this worked in the Theme Editor, it would indeed be the best plugin ever.

   Was looking for this easy possibility to make structured css! Thanks Only one little question the icons from the font “codicon” are not working. Anything I can do to get that working?

   Really useful plugin, the only thing whats missing is to resize the coding area, so annoying to type in a such cramped space or at least integration of word wrap would be great, thanks!

   Honestly, this is the only sane way of writing CSS inside WordPress, making the experience as good as coding on your computer in a proper editor. I don’t understand why this doesn’t have thousands of downloads. It’s been a massive game-changer at our agency, allowing people at all levels to start learning and using SASS. A couple of things that could improve on this: Support for multiple files, so we could use SASS partials. An improved live editor, which feels a little rudimentary. For example, offer an option to align the editor underneath the preview pane, and add buttons to resize the preview pane (similar to customizer) for testing responsive design. But anyway, soooo much gratitude. If you need more support to keep developing this, we’d be completely behind paying for a pro version, as long as there’s developer option for unlimited sites, because Instant CSS is basically part of our WordPress Core here now 😊 Thanks again!
