Required Action Available

Group: process-and-task-completion • Guideline: complete-tasks

Summary in Plain English

Where the user must do something to move to the next step, the interface says so.

Why It Matters

A process that stalls without saying why reads as a broken page. The user most likely to give up is the one who cannot see the unfilled field.

Scope: When This Applies

The draft's own conditions, quoted from guidelines/groups/process-and-task-completion/complete-tasks/required-action-available.md.

Applies when

  • the user needs to complete an action in order to proceed to the next step.

Examples from the Draft

Worked examples the W3C editors wrote into the provision itself, not examples invented here.

This would apply when the user needs to agree to the terms and conditions before they can submit the form.
