I’ve created a collection of blog posts, connected the text using a rich text field and added a class. Unfortunately, there’s just no option to create paragraphs.
The on-screen editor, removes the spaces after hitting save. The same thing happens with the backend CMS blog page.
All elements styling should be before you connect it to dynamic content.
I am usually just add one more rich text with the same class as my dynamic one, but do not connect 2nd rich text to dynamic collection. Then I am styling “static” rich text and it shows up on dynamic too.
