Concept cluster
Compare a general modal task, a consequential decision, and focused media viewing with the page made inactive.
Is the task about acting, confirming a consequential decision, or viewing media?
Try it
Compare all three behaviors
Shared comparison scenario: A project item opens a focused overlay while the underlying workspace remains unavailable until the user finishes or closes it.
This context stays fixed. Switch concepts to observe the mission, edge case, and specimen specific to each behavior.
Modal dialog
Use a Modal dialog for a general contained task; use Alert dialog for a short consequential decision and Lightbox when viewing media is the task.
Your task
Open the dialog, tab through every control, cancel with Escape, and verify focus returns to Edit member.
Edge case to verify
A validation error keeps the dialog open, links the message to the invalid field, and moves focus only when submission fails.
Mission
Open the dialog, tab through every control, cancel with Escape, and verify focus returns to Edit member.
Select a numbered marker on the schematic, or use the list below, to see its role. The schematic shows the concept's representative state.
Backdrop
The layer that separates a modal surface from inactive page content.
These descriptions fit every concept in the cluster, so none of them is enough to decide.
