Div is extending out of the viewport

So I have been struggling with this problem for the past hours. So when I go to the smaller version of the mobile portrait mode my Flex-V_newscards div starts going out of the viewport instead of being responsive. There is no minimum width on it from what I found. I probably overlooked something, but I just simply can’t find it.
Thanks in advance for helping!

Here is my site Read-Only:

Check the contents of the button news widgets below it, they’re overflowing, not the cards.

Yeah for some reason, the widgets didn’t want to shrink any further. I made some things smaller and stacked something vertically and it worked. Thanks a lot for the help!
