Keyboard navigation is essential for visually impaired users who rely on the Tab key or arrow keys to move through a website. To ensure a smooth experience, several key factors should be considered.

Make keyboard focus visible. By default, browsers provide focus indicators, such as dotted or solid outlines, but these can be customized to align with brand colors while maintaining high contrast for visibility.

Follow a logical focus order. The focus should match the visual layout, typically moving left to right and top to bottom, prioritizing essential content. All interactive elements—buttons, links, forms, dropdowns, and modal dialogs—must be accessible via the keyboard, just as they are for mouse users.

Use semantic HTML and ARIA roles. Elements like <header>, <nav>, <main>, <section>, and <aside> help assistive technologies provide a clear page structure. Screen readers use these landmarks to generate a navigational map, allowing users to jump directly to key sections. Adding ARIA roles and descriptive labels enhances this experience, making navigation more intuitive.^[1]
