Width of custom ID element

Please refer to below image…on desktop the containers display the text fine - lower breakpoints the text wrap, but you can see there is plenty of space to increase the width of the elements for both the contains (arrow 1) and/or the text element (arrow 2).

I’ve assigned a unique class name to the text element, but can’t seem to find where I can increase or change the width of this element - or the width of the parent container…

I’m not sure if this is a flexbox thing, or a CSS thing? Any help appreciated.
