# roblox gui

## When to Load

HUDs, menus, shops, dialogs, world UI, and layout bugs on phone, tablet, desktop or TV.

## Quick Reference

- Mobile first: design on the smallest landscape phone with touch controls, then grow (full.md §11).

- Reserve top bar, thumbstick, jump, chat; interactive UI in `CoreUISafeInsets`; place by measured `AbsolutePosition`/`AbsoluteSize`.

- Check every element pair that can show together; reflow, don't shrink.

- Gamepad: one `SelectedObject` owner, `SelectionGroup` bounds, restored focus, layered Back (§8).

- Console: TV-safe area, `ViewportDisplaySize`, no chat window.
