CSS div width issue in wide screens - html

Question

I am developing a website using a bought template. Everything seems to be perfect. However, I have an issue with a section of the html code where it works fine in normal screen sizes but in extra wide screen size, the div size is reduced to a strip. The images below demonstrate this:
This is how the div is in normal screens
And when the screen is extra wide, for example in devices with more than 15" screen, this is how the div looks like:
My main challenge however is that I really don't know which property is controlling this from the css file. I tried inspecting the code from chrome and the most consistent property is the box-sizing property and the value is set to inherit. Let me share the html code for this section of the div for further clarity.

Kindly advise as I am not that good in frontend. The css file is too big to share the code here, but I can get snipets of the sections that are used by the html section. Thank you.
Edit: Adding CSS COde Snippet
So, I have copied the code to JSFiddle and here is the link:

Answer 1

You can try to specify:
min-width: someValue
and the element won't be smaller than this value;
