What is Accessibility (a11y)?
Designing and building websites so they can be used by everyone, including people with disabilities.
Why It Matters
Accessible websites reach a wider audience, meet legal requirements, and provide a better experience for all users.
Real-World Example
Adding alt text to images so screen readers can describe them to visually impaired users.
“Understanding terms like Accessibility (a11y) matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
