Field Error

Display errors below a form control to indicate invalid or missing input.

  • For browser-side form validation, change the field error’s role from role=status to the more aggressive role=alert to gain the screenreader user’s immediate attention.
  • For server-side form validation, post an error Block Message at the top of the form using role=alert to notify the screenreader user.

Guidelines

Dense forms is for special use cases only.

  • Never use dense forms when a form is the primary purpose of a page or a modal. For example, never on a registration form, a profile form, or a quiz.
  • Use when a form needs to fit into a relatively tight container, such as a panel or a sidebar.
  • Use for simple forms with only a handful of questions. For more involved forms, give the form more space and use the default styling.

Dense form can solve layout issues with individual form fields.

  • Use dense form on a single form element to tighten its visual style. In the example below, the inline "Other" field has .comet-form--dense applied, allowing it to sit on the same line as a checkbox and label.
  • Use this technique sparingly. Review combined default/dense forms with a designer.
