[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;} ![](https://secure.gravatar.com/avatar/6cbd96106c76dfd85e755f1aba9c463817d1b9d5dd74bb64b84dad2b458a790c? s=60&d=retro&r=g) ### 󠀁[Отличный плагин](https://wordpress.org/support/topic/%d0%be%d1%82%d0%bb%d0%b8%d1%87%d0%bd%d1%8b%d0%b9-%d0%bf%d0%bb%d0%b0%d0%b3%d0%b8%d0%bd-991/)󠁿 [Сергей](https://profiles.wordpress.org/serzh82/) 20 Novembre 2025 1 risposta Отличный плагин ![](https://secure.gravatar.com/avatar/ff57a8df8c1ffea97f5c0992bed6943b19a831dbc8b3a0f9153dc4421fa1c4cc? s=60&d=retro&r=g) ### 󠀁[Моя оценка: пять звезд](https://wordpress.org/support/topic/%d0%bc%d0%be%d1%8f-%d0%be%d1%86%d0%b5%d0%bd%d0%ba%d0%b0-%d0%bf%d1%8f%d1%82%d1%8c-%d0%b7%d0%b2%d0%b5%d0%b7%d0%b4/)󠁿 [shooter604](https://profiles.wordpress.org/shooter604/) 14 Novembre 2025 1 risposta Очень классные возможности!

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 🙁 [ Leggi tutte le recensioni di 25 ](https://wordpress.org/support/plugin/blocks-css/reviews/) ## Contributi e sviluppo “Blocks CSS: CSS Editor for Gutenberg Blocks” è un software open source.
