Introduction

When building a website that anyone can visit, including people with vision or hearing difficulties.
When you want your website to work well with screen readers or keyboard navigation.
When you want to follow laws or guidelines that require websites to be accessible.
When you want to improve your website's usability for all users, not just those with disabilities.
When you want to reach a wider audience and show you care about all visitors.
Syntax
HTML
No specific code syntax applies here, but accessibility involves using semantic HTML elements and ARIA attributes properly.
Use semantic HTML tags like
,
Add ARIA labels and roles to describe elements when needed for assistive technologies.
Examples
This button has an ARIA label to describe its purpose to screen readers.
HTML
<button aria-label="Close menu">x</button>
Using the <nav> element helps users and assistive devices know this is the main navigation.
HTML
<nav>
  <ul>
    <li><a href="#home">Home</a></li>
    <li><a href="#about">About</a></li>
  </ul>
</nav>
Sample Program
