Hi @chmst, I could be doing something wrong but I'm not matching the BEFORE condition (or I misunderstood it)

I took a sample multilingual joomla 5.4 nightly installation and added to 'Article (en-gb)' the Banners Sky image as Intro image and set the class 'border border-dark', saved and added to the user.css this css rule: .border.border-dark {width:50%;} and then went to the front-end (cleared cache) and the CSS was accepted/handled, the image is 50% width... what did I miss?

✅ Final test before merge with JBT

• Seen the problem before PR, article view displays custom image class settings for intro and full image, but not in Articles module
• Applied PR with gh pr checkout 46619
• Intro and full images are shown with custom image class settings in Articles module
