Good morning,
I am building a website using PageBuilder and am finding that some of the Headers, probably the H1 tags, are capitalized, how can I change this?
The site is not publically visible, please see screenshot.Pagebuilder query
The titles on the blog posts and a few other places aren’t captialixed, but the headers in the buttons and the H1’s are.
I read a few threads and tried adding this to the Custom css
