1. Accessibility in HTML

Accessibility ensures your web content is usable by everyone, including people with disabilities. HTML provides built-in attributes and ARIA (Accessible Rich Internet Applications) roles to make your content accessible.

1.1 Example of Accessible Forms:

    Email:
    
    Submit

            

Key Points:

• Use the <code>aria-required</code> attribute to indicate required fields.
• Ensure labels are linked to inputs using the for and id attributes.

2. ARIA Roles

ARIA roles help define elements' purpose for assistive technologies, such as screen readers. Common ARIA roles include:

• role="navigation": Marks navigation sections.
• role="main": Denotes the primary content area.
• role="button": Enhances interactive elements.
