Anatomy

Dashed frames are invisible state providers; shaded shapes own real DOM. Numbered pins match the list below.

A wireframe sketch of the assembled component. Each numbered marker matches a part in the list that follows.

  1. Dialog

    Wrapper-free provider for the composed modal state. Does not add a DOM element.

  2. DialogTrigger

    Button that opens the modal. Owns a DOM element.

  3. DialogContent

    Native modal surface containing the task. Owns a DOM element.

Step by step

  1. 1

    Add the main part

    Start with Dialog and a DialogTrigger.

  2. 2

    Add the supporting parts

    Compose the heading, content, and actions inside DialogContent.

  3. 3

    Make the behavior clear

    Name the content from its visible heading and provide an explicit close action.

    Exampletsx
    <Dialog><DialogTrigger>Edit profile</DialogTrigger><DialogContent aria-labelledby="profile-title"><h2 id="profile-title">Edit profile</h2></DialogContent></Dialog>

Keyboard

Esc
Closes and restores trigger focus.
⇥
Cycles inside the modal.

Forms and accessibility

Forms inside DialogContent submit normally; method=dialog closes the modal without navigation.

Accessibility checklist

  • Connect DialogContent to a visible heading with aria-labelledby.
  • Keep the task short enough to understand without the page behind it.
  • Include an explicit close action even when Escape can dismiss the modal.
