Keeping/connect image and subtitle text box together (responsive behavior)

[biografie]

Dear Laytheme Forum,

I have another question regarding layout and responsiveness:
I would like to “link” two elements together — in my case:
an image (with the title “Ar.Mut - Was wäre wenn”),
and a subtitle (text field):

https://ar-mut.ch/wp-content/uploads/2026/03/Bildschirmfoto-2026-03-26-um-15.55.01.jpg
-> I have marked the relevant area in the screenshot with a box.

The goal is that when I resize the browser window, these two elements stay properly aligned and maintain their relationship — meaning:
they should remain nicely stacked (one above the other),
and not overlap or shift into each other.

Is there a way in Laytheme to group or connect these elements so they behave responsively as one unit?

If yes, how can I achieve this?

Here the page: https://ar-mut.ch/start-test/

Thanks a lot for your help!
Best regards,
Dennis

hey please select your image, then choose "edit caption"

or simply put the image and the text element into a stack/group element:
in +more → +stack/group:
