Question

css

Hello. I order SPA on the freelance exchange. The backend is already written. The question arose, how best to transfer the work to a freelancer?
In the first option, what would one developer do and adaptive layout and React.
In the second option, order the layout from one freelancer, and the React developer will make the logic.

Answer 1

it is better that the one who typesets better, if you want it well

Answer 2

React developer will cut components out of this anyway. Fuck him someone else's layout, all the same to break and redo everything.
It's easier to do everything yourself))
