Hi and welcome to WordPress Core Trac!

I'm happy to reconsider the change for both themes, but I explained my reason for editing blocks.css instead of style.css in the first comment on 58915. I was more concerned with the possibility that some sites already depended on block display for their custom <summary> elements than the case of someone manually adding a <details> element later. The Details block needed a different display value, and the ticket only fixed that.

Other notes:

  • The Classic Editor does not disable block-related styles, so your site still fetches the theme's blocks.css. You (and others) technically could add the class <details class="wp-block-details"> in the classic code view, but you wanted to add more CSS for the summary element than just the display property anyway.
  • Having multiple details elements is not recommended for an FAQ-style section, which would fit the 'accordion' pattern better. See #60335.

    11Hi! 🙋🏻‍♂️

    3 I noticed that when I added details / summary elements to my WordPress page, the little triangle thingy was not there. It's an indicator to show if the “details” element is opened or closed. After some testing, I fixed the problem by adding the following style to the “Additional CSS” area…

    24 I was wondering, if this issue was addressed, why did I still see a problem? That's when I looked at the file being modified. It's the blocks.css file.

    2626I use the “Classic Editor” plugin on my website, which disables Gutenberg. Additionally, the details and summary tags were being added to an article page. Essentially, I was building an FAQ page.

    28 So, perhaps that means the style.css file should be updated too. **It looks like “summary” should not be part of that CSS declaration.** And since ticket 58915 mentioned the Twenty Thirteen theme, perhaps that style.css file needs to be fixed too…
