Why Accessibility (a11y) Matters in Modern Web Development

1. Hook

Show two versions of the same website:

• Version A: Missing alt text, tiny font size, no keyboard navigation.
• Version B: Fully accessible, screen-reader friendly, high-contrast colors.

Narration:

“One in six people globally live with some form of disability.
Which version of your site do you think serves them best?”

2. Introduction

• Accessibility (often called A11y) ensures that everyone — including people with disabilities — can use and enjoy your website.
• It’s not just a moral duty; it’s a business advantage.

3. What Accessibility Covers

• Visual impairments: color blindness, low vision, screen readers.
• Hearing impairments: captions, transcripts.
