I completely understood what you meant. I am not a native English speaker, so I use a translator. Is there anything I need to do? If so, please rephrase.
Alas, I cannot edit my post. If it helps with the problem, I will make a comment as recommended.
Use case or problem
At the moment, clicking on the internal link takes us to the entry. This becomes inconvenient if the information in the post is small in size. It is also inconvenient to implement a return to the main entry after reading the secondary entry.
Proposed solution
The use case is to open the contents of the record in a modal window when you click on the internal link. Entries that have a small appearance, but due to the special form of presentation of the information can break the layout. This applies to: snippets of code, tables and images. This way of presenting information can also be used as an explanatory note from the author.
I made a video animation for the example. I propose to implement the display like this: VIDEO
Current workaround
At the moment there is no solution. I asked the question in the next thread How to display internal links in a popup/modal window? . The plugin solution does not suit me. I want it to be the clicking on the link that opens the modal window. Hovering over the link is not a user friendly solution. Also, the plugin opens the entry in a small window. It is inconvenient to enlarge the window every time. And also there is no way to close the window when you click on the main entry. I mean, I would like to be able to close the modal window when you click not only on the “cross”, but also on the darkened area.
