Implementing keyboard navigability in your email marketing involves using proper HTML and ARIA (Accessible Rich Internet Applications) attributes. Here are some key elements to focus on:
Tab Order: Ensure that the tab order of elements in your email makes sense. Users should be able to navigate through the content in a logical sequence by pressing the 'Tab' key. Focus States: Make sure that focus states are clearly visible. This means that when an element is focused (selected by keyboard navigation), it should be highlighted or outlined in a way that is easy to see. ARIA Roles: Use ARIA roles to provide additional context to screen readers. This can help users understand the purpose of each element better. Skip Links: Include skip links to allow users to bypass repetitive content and navigate directly to the main content. This is particularly useful for users with screen readers.
