How to insert a link of another post inside the content of a post and customize

Hello,

I inserted the link to another internal article in the content of my article and the result was as you can see from the following link : https://magazine.pagesjaunes.online/forum-des-pme-du-gecam-la-problematique-du-financement-au-coeur-des-debats/

I’d like to be able to customise the presentation or layout of these internal articles, but I don’t know where to do it. For example, I’d like to remove the left and right borders, and remove the footer from the presentation where the name of our site, the comment icon and the share icon are located.

I tried to get into “Theme Panel —> Custom Code —> Custom CSS” and I placed this code:

.wp-embed {
background: #f6f6f6;
border-top: 1px solid #dcdcde;
border-bottom: 1px solid #dcdcde;
}
.wp-embed-footer, .wp-embed-site-title {
display: none;
}

But I don’t see any changes when I save and refresh.
Please guide me on how to customise this presentation.

Hello,

Thank you for your quick response to my concern.
I understand that this WordPress embed cannot be modified to my liking.

I’d also like to know if there’s a way with Newspaper to make a link from another article appear in the body of an article in this way. Is there a possible configuration with NewsPaper?

Thank you.
