In an ideal world, we approve the concept, design all layouts with different resolutions, prepare a UI Kit, TOR for animations, and only then transfer everything entirely to the developers.
But in practice, deadlines often do not allow you to follow this path, and you have to transfer layouts in parts.
What is important to have ready with such a transfer: a fully finished one of the adaptive layouts (desktop 1440 or mobile 375, depending on priorities) and a UI Kit assembled for it.
While your layout is in constant refinement and changes, it is very important to highlight these changes to developers and report on finished blocks/pages not only with a message in the project chat.
There are several more options for how you can do this:
Checklists and Notes Widgets
We have put together a separate large checklist for you when finalizing layouts.
