Modal structure
A dialog usually needs a viewport-level backdrop, a centered panel, a heading, content, actions and correct accessibility behavior. Tailwind can style all of these layers, but it does not provide the JavaScript behavior automatically.
Accessibility requirements
A real modal should manage focus, provide an accessible name, trap focus appropriately, close according to its interaction model and restore focus to the triggering control.
Use framework primitives when possible
For complex dialogs, use a tested accessible dialog component or the native HTML dialog element rather than implementing focus management from scratch.
