Blocks CSS: CSS Editor for Gutenberg Blocks

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

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 34% 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. A declining trend compresses what a buyer would pay.

   Works like a charm on any of my recent WP projects. [EDIT]I need to change my review.On some setups, I get two CSS editors shown in the “Custom CSS” attribute panel, and only contents of the second instance are getting saved.Problem:Two CodeMirror editors are displayed in the Custom CSS panel of the Blocks CSS plugin instead of one. Both editors are located in the same container. Assumed Root Cause:WordPress enables React StrictMode by default in the Block Editor. React StrictMode runs useEffect hooks twice to detect potential side effects. Analysis:The Blocks CSS plugin initializes CodeMirror in a useEffect hook.Since this useEffect doesn’t have a cleanup function that checks whether CodeMirror is already initialized, wp.CodeMirror() is called again on every mount cycle. With StrictMode enabled, this means: twice on the same DOM element. Probable Solution:The useEffect hook should implement a cleanup function that prevents CodeMirror from being initialized multiple times on the same element.Side Notes:This only happens in some of my setups. I couldn’t figure out any possibly conflicting theme, plugin or code snippet. So I assume it might be something like a timing issue. Conclusion:I won’t change the 5-star rating, because despite of this problem the plugin does its job. And I know how to handle this issue by a simple CSS rule to hide all Block CSS CodeMirrors except the last one:#o-css-editor .CodeMirror:not(:last-child) { display: none;} This topic was modified 5 months, 1 week ago by maltmann. Reason: Revision after issues in some setups

   “Essential, Useful Tool, Completes the Block Editor, Should be part of the core,” The one thing they don’t mention is how quick and genuinely concerned the support is.

   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 🙁

   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.
