On a site using J3! (latest) and SP3.X (latest) I have several pages with columns based rows.
When I use the RAW HTML, the content does not fill the full width of the column it is inside. This has also been seen on a columnn based page with an SP Accordion in it.
The only way I can force the content to fill the column is to use a CSS rule such as:
#sppb-addon-1676558852044 {width:100% !important;}
Which when I have loads of addons affected, is a real unnecessary pain in the rear.
I have checked that this does not happen on a different site with exactly the same row and column and content.
In the hidden content I've provided the URL of the affected pages (where I have to use CSS to sort the issue) and a page where I have not applied any CSS so you can compare. Also I have given the admin URL and credentials.
Hope you can help!
