Study Notes

Visual Focus States

Sighted keyboard users rely on visually displayed keyboard focus to navigate web applications.
WCAG 2.4.7 requires visible focus states to help users know where they are.
Visual focus states can be customized, but must meet or exceed a 3:1 color contrast ratio according to WCAG 2.1.

Various Component States

Components, such as checkboxes, require distinct visual states to indicate their state.
States to consider: default, focused (not selected), focused (selected), not focused (selected), and disabled.
Each state should have a visually distinctive element to convey the overlap of states.

Forms

Always include visible labels to help users understand the purpose of each form field.
Avoid using placeholder text as it can be confusing.
Design helpful error messages that include error text and explanation of how to fix the error.
Guide the user in completing the form successfully by setting clear expectations and providing safeguards.
Avoid setting time limits on completing forms, and provide ways for users to edit, save, or restart the form.

Best Practices

Design interactive controls and form inputs with clear visual differences for all states.
Provide clear guidance and safeguards to remove barriers for people with cognitive disabilities and provide a more enjoyable experience for everyone.
