As of WP 5.8.1 (or 5.8.0) the Gutenberg Editor gets to be default even for Widgets.

So I've started to create some Widgets with Gutenberg blocks. My issue is that if I add custom CSS to the blocks (through the block editor's custom css tab, wrapped in the selector {...} statement), it gets stripped out when the page is rendered.

enter image description here

Question: is this

  • a bug
  • an intended behaviour
  • or am I doing something wrong ?
  • How are you adding CSS to the blocks? Sep 29, 2021 at 4:00
  • @JacobPeattie through the block editor options -> custom css tab and with the selector {...} wrapper. See my edit in the question.

  • That is not a standard WordPress feature. Is that from a plugin? Or perhaps it's a feature of specific blocks your using? Either way, you would need to ask the author of that feature. Sep 29, 2021 at 15:23
  • @JacobPeattie Hmmm... I wasn't aware of that, but it looks like the theme I'm using incorporates the Blocks CSS Editor Plugin ... This resolves my question (but not my problem). - I'd accept that as an answer if you want to wirte it, otherwise I'll just delete the question and rethink everything. Thank you.
