Implementing keyboard navigation in emails involves several best practices:
Focus Order: Ensure that the focus order of interactive elements (like links and buttons) is logical and intuitive. This can be done by using the tabindex attribute. Skip Links: Provide skip links to allow users to bypass repetitive content and navigate directly to the main content. ARIA Roles and Attributes: Use ARIA (Accessible Rich Internet Applications) roles and attributes to provide additional context to assistive technologies. Keyboard Shortcuts: Implement keyboard shortcuts for frequently used actions to enhance user convenience. Focus Indicators: Ensure that focusable elements have clear visual indicators when they are selected.
