The meta box form when viewed in my wordpress dashboard is perfect. The css looks really professional. But when inputting using a shortcode on a single page in elementor, it does not look the same (and does not look good). As an experiment, I removed all of my own custom CSS to see if there was something in there doing something, but there was not. I use the elementor hello theme, which should be bare boned and inputting things as intended.
I am wondering if you have the original CSS for the wordpress dashboard form so that I can duplicate it over to my single page template on elementor?
There is a little CSS code to style the frontend dashboard, it is just a table to display list of posts and some buttons to delete/edit a post. I don't know what is not good in your case, can you please share some screenshots of the issue on your site?
