CSS of Smart Select

I am going to enlarge the screen size on iPad by using body{zoom: 2;}. I can specifically modify the font-size of numbers of element. But I don’t catch on css of “smart select” specific font-size at the elements in red outline. Anybody can give me some advice?

Use browser dev tools inspector to evaluate those elements, it is --f7-list-item-after-font-size and --f7-list-chevron-icon-font-size List View (Table View) | Framework7 Documentation
