Semantic HTML and alt text are foundational to screen reader compatibility. Semantic HTML uses HTML5 elements that provide meaning to the content, making it easier for screen readers to interpret. Alt text provides descriptive information for images, allowing screen readers to convey visual content to users who cannot see them.

Keyboard shortcuts and navigation are essential for users who rely on screen readers. These features enable users to move through content efficiently without a mouse. Proper focus management ensures that as users navigate, the screen reader announces the relevant content.

Accessible Rich Internet Applications (ARIA) and role attributes enhance screen reader compatibility by providing additional context to dynamic content. ARIA labels and live regions, for example, inform users about changes in content, ensuring they are aware of updates in real-time.

Skip navigation and tab index features improve the user experience for screen reader users by allowing them to bypass repetitive content and navigate directly to the main sections of a page. This streamlines the interaction process, making it more efficient.

Overall content accessibility is the goal of screen reader compatibility. By integrating these various elements and practices, developers ensure that their content is usable by everyone, including those with visual impairments. Achieving this level of accessibility promotes inclusivity and equal access to information.
