Using HTML for Screen Reader Accessibility
Screen readers are assistive technologies that convert on-screen content into speech or braille output. Writing semantic and accessible HTML ensures that all users, including visually impaired individuals, can access your content effectively.
What Screen Readers Read
- Headings (
<h1>...<h6>) β Used to navigate the page hierarchy. - Alt text on images (
altattribute). - Form labels (
<label>andaria-label). - Landmark elements (
<nav>,<main>,<footer>). - ARIA roles and properties.
Best Practices for Screen Reader Support
- Use semantic HTML elements for structure and clarity.
- Always associate form inputs with a label.
- Use
aria-labeloraria-labelledbyfor custom UI components. - Use landmarks like
<header>,<nav>, and<main>for easy navigation. - Avoid using
display: nonefor content that should be read by screen readersβusearia-hidden="true"when appropriate.
Example
<form>
<label for="email">Email address:</label>
<input type="email" id="email" name="email">
<button aria-label="Submit form">Submit</button>
</form>
